13:00 Fernando Quadro: Etapas básicas para criar seu WebGIS
sur Planet OSGeoA melhor prática para criar um sistema WebGIS é armazenar todos os seus dados espaciais em um servidor PostgreSQL habilitado para PostGIS. Garanta que a indexação espacial seja aplicada para recuperação de dados mais rápida.
Você pode facilmente construir uma interface intuitiva e amigável usando HTML básico, CSS, Bootstrap e JavaScript.
Use Leaflet ou OpenLayers como sua biblioteca de mapeamento padrão!
Para filtrar dados ou executar consultas, siga estas etapas:
Colete a entrada do usuário e envie-a para seu script de backend por meio de uma solicitação AJAX.
Valide a entrada no backend e busque os dados necessários do banco de dados PostgreSQL usando consultas SQL.
Prepare os dados no backend e envie-os de volta para o cliente (interface do usuário).
O cliente receberá os dados por meio da mesma chamada AJAX e os formatará em camadas Leaflet. AJAX é assíncrono.
Estilize suas camadas de forma eficaz usando funções JavaScript.
Exiba as camadas no mapa.
Ajuste automaticamente a visualização do mapa para se ajustar à extensão do recurso pesquisado.
Adicione-os a um controle de camada para alternar a visibilidade entre ligado e desligado.
Crie dicas de ferramentas ou pop-ups para exibir informações detalhadas.
Se o usuário pesquisar por um único recurso, desenhe um círculo, linha ou polígono ao redor dele e amplie o recurso.Estas são as etapas básicas para exibir dados em um sistema WebGIS.

Fernando Quadro: WFS-T com OpenLayers, PostGIS e GeoServer
sur Planet OSGeoOutro dia eu estava navegando pela internet quando “esbarrei” com um post muito interessante sobre como utilizar o WFS Transactions (WFS-T), para salvar feições no PostGIS a partir de uma aplicação web com OpenLayers.
Eu já tinha postado algo bem similar a isso a um bom tempo atrás, mas já estava bastante desatualizado, então eu decidir traduzir e (re)postar esse material aqui no blog.
1. O Projeto
Essa aplicação está postada no GitHub e usa no frontend React/OpenLayers para atualizar dados de recursos GIS armazenados em um banco de dados PostGIS usando transações WFS (facilitadas pelo GeoServer).
2. Objetivo
O objetivo era exibir um recurso WFS em um mapa com OpenLayers e gravar alguns dados no PostGIS cada vez que o recurso fosse clicado. Isso foi feito incluindo a propriedade interation nos dados do recurso que rastreou o número de cliques.
Foi utilizado o docker kartoza/docker-geoserver para montar o backend com GeoServer e PostGIS. Graças ao trabalho duro do Kartoza, isso foi tão fácil quanto executar docker-compose up no diretório apropriado (mais instruções aqui).
Alguma configuração foi necessária para criar uma tabela e um registro de exemplo no PostGIS. Uma vez que isso foi concluído, mais algumas etapas foram necessárias para criar um workspace, store e uma camada no GeoServer para publicar a tabela do PostGIS.
A etapa final é publicar a camada no GeoServer e aí começa a diversão!
3. O Frontend
O aplicativo frontend foi baseado em React com OpenLayers. Alguns call-outs específicos e lições aprendidas são compartilhados abaixo, mas confira o projeto no GitHub para o código-fonte completo.
3.1 Criando a camada WFS do GeoServer no OpenLayers
Definir a camada e os estilos do WFS foi simples usando a estratégia bbox padrão, usada para instruir o OpenLayers sobre como/quando carregar os recursos do WFS. Veja:
import VectorSource from 'ol/source/Vector'; import GeoJSON from 'ol/format/GeoJSON.js'; import {bbox as bboxStrategy} from 'ol/loadingstrategy.js'; import VectorLayer from 'ol/layer/Vector'; const GEOSERVER_BASE_URL = 'http://localhost:8600/geoserver/dev'; // create geoserver generic vector features layer const featureSource = new VectorSource({ format: new GeoJSON(), url: function (extent) { return ( GEOSERVER_BASE_URL + '/ows?service=WFS&' + 'version=1.0.0&request=GetFeature&typeName=dev%3Ageneric&maxFeatures=50&' + 'outputFormat=application%2Fjson&srsname=EPSG:3857&' + 'bbox=' + extent.join(',') + ',EPSG:3857' ); }, strategy: bboxStrategy, }); const featureLayer = new VectorLayer({ source: featureSource, style: { 'stroke-width': 0.75, 'stroke-color': 'white', 'fill-color': 'rgba(100,100,100,0.25)', }, });3.2 Usando React Refs para acessar objetos OpenLayers
Ao integrar o OpenLayers com o React, é importante inicializar os objetos do OpenLayers uma vez (por exemplo, em um hook onload) e usar Refs para manter referências a esses objetos entre as renderizações.
Isso também permite que a versão atual desses objetos seja acessível em funções de retorno de chamada. Caso contrário, uma versão obsoleta do objeto pode ser fornecida ao retorno de chamada (capturada no momento do fechamento do retorno da chamada).
// react import React, { useEffect, useRef } from 'react'; import Map from 'ol/Map' function MapWrapper(props) { // refs are used instead of state to allow integration with 3rd party map onclick callback; // these are assigned at the end of the onload hook // [https:] const mapRef = useRef(); const mapElement = useRef(); const featuresLayerRef = useRef(); // other logic removed for brevity // react onload hook useEffect( () => { // create map const map = new Map({ // config removed for brevity }) // save map and featureLary references into React refs featuresLayerRef.current = featureLayer; mapRef.current = map },[]) return ( <div> <div ref={mapElement} className="map-container"></div> </div> ) } export default MapWrapperNo exemplo acima, os objetos OpenLayers map, featuresLayer e até mesmo o div mapElement são armazenados como Refs para uso em funções de retorno de chamada fora do React.
3.3 Executando transações WFS a partir de funções de retorno de chamada do OpenLayers
O ponto crucial de todo esse aplicativo é enviar as solicitações de transação WFS para o GeoServer com os dados de recurso do OpenLayers para gravar no PostGIS. Isso é tratado na função de retorno de chamada no onclick do mapa.
import WFS from 'ol/format/WFS'; import GML from 'ol/format/GML32'; const GEOSERVER_BASE_URL = 'http://localhost:8600/geoserver/dev'; // map click handler - uses state and refs available in closure const handleMapClick = async (event) => { // get clicked feature from wfs layer // TODO: currently only handles a single feature const clickedCoord = mapRef.current.getCoordinateFromPixel(event.pixel); const clickedFeatures = featuresLayerRef.current.getSource().getFeaturesAtCoordinate(clickedCoord); if (!clickedFeatures.length) return; // exit callback if no features clicked const feature = clickedFeatures[0]; // parse feature properties const featureData = JSON.parse(feature.getProperties()['data']); // iterate prop to test write-back if (featureData.iteration) { ++featureData.iteration; } else featureData.iteration = 1; // set property data back to feature feature.setProperties({ data: JSON.stringify(featureData) }); console.log('clicked updated feature data', feature.getProperties()) // prepare feature for WFS update transaction // [https:] const wfsFormatter = new WFS(); const gmlFormatter = new GML({ featureNS: GEOSERVER_BASE_URL, featureType: 'generic', srsName: 'EPSG:3857' // srs projection of map view }); var xs = new XMLSerializer(); const node = wfsFormatter.writeTransaction(null, [feature], null, gmlFormatter); var payload = xs.serializeToString(node); // execute POST await fetch(GEOSERVER_BASE_URL + '/wfs', { headers: new Headers({ 'Authorization': 'Basic ' + Buffer.from('admin:myawesomegeoserver').toString('base64'), 'Content-Type': 'text/xml' }), method: 'POST', body: payload }); // clear wfs layer features to force reload from backend to ensure latest properties // are available featuresLayerRef.current.getSource().refresh(); // display updated feature data on map setFeatureData(JSON.stringify(featureData)); }O código acima é executado quando o recurso WFS é clicado. Isso aciona a seguinte lógica:
Linhas 11-14: o objeto de feição OpenLayers clicado é identificado
Linhas 17-25: a propriedade iteration do recurso é aumentada em 1 e salva de volta no recurso
Linhas 30-38: o recurso é convertido no formato apropriado para a transação WFS
Linhas 41-48: a solicitação de transação WFS é definida para a instância do Docker GeoServer criada anteriormente no projeto
Linhas 52-55: solicita que o OpenLayers recarregue os dados WFS do GeoServer para garantir que as propriedades de atualização estejam presentes4. Para onde ir a partir daqui
Agora que temos um exemplo de como gravar dados GIS do OpenLayers no PostGIS, podemos expandir este aplicativo para suportar criação e edição de recursos mais complexos. Por exemplo, desenhar recursos com o OpenLayers.

My pal Giuseppe Sollazzo has an incredibly wide range of interests which include geography and embroidery. He recently completed his latest project – “Mission accomplished ? Choropleth of London councils by population, with a terrible palette choice! Data from wikipedia, shapefile from Ordnance Survey”
I asked him what prompted the idea for this embroidered map – “The idea fundamentally came from my recent interest in trying more analogue experiences while not completely giving up my data & digital passions. Which means I’m doing less internet, more ham radio, and less javascript maps and more physical ones. Having recently learned crochet, I thought that embroidery would be great for data visualization. It takes a while so it’s an act of love to data ? But the result is oddly pleasant.”
I think we can all agree that it is more than oddly pleasant! If there was a Nobel Prize for geogeekery, I think Giuseppe would be a winner.

3liz: Sortie de Lizmap Web Client 3.8
sur Planet OSGeoLizmap Web Client 3.8Nous sommes heureux d'annoncer la sortie de Lizmap Web Client 3.8, la nouvelle version majeure de l'application.
Financeurs
Pré-requis et installation
Il est désormais requis d'avoir un QGIS serveur minimum 3.28. Cependant, nous recommandons fortement d'utiliser une version LTR plus récente, comme la version 3.34. Consultez la feuille de route QGIS.
Pour utiliser pleinement cette version 3.8, n'oubliez pas de mettre à jour votre extension Lizmap dans QGIS bureautique. Nous avons écrit un article dédié sur cette version.
Fonctionnalités Demande de tuile unique pour toutes les couchesJusqu'à la version 3.7, Lizmap Web Client effectuait une requête HTTP au serveur QGIS par couche visible.
Désormais, grâce à Faunalia qui a contribué au code source, Lizmap Web Client peut effectuer une seule requête HTTP
GetMapà QGIS Serveur pour toutes les couches visibles (sauf pour les couches ayant un cache actif).Les deux méthodes ont des avantages et des inconvénients. Cette nouvelle option de l'extension peut être très utile pour les projets lourds.
Petite astuce également disponible sur la dernière version 3.7, il est désormais possible de désactiver le permalien automatique avec la case à cocher.
AccrochageLorsque l'accrochage est activé sur une couche, l'utilisateur peut désormais sélectionner dans l'interface Web sur quelle couche s'accrocher.
Cette nouvelle fonctionnalité a été développée par Faunalia.
InfobulleLa fonctionnalité d'Infobulle de Lizmap Web Client a été grandement améliorée dans cette dernière version. Avant, côté gauche de la capture d'écran, vous ne pouviez sélectionner qu'un champ à afficher lorsque vous survoliez une entité dans le navigateur Web. Maintenant, comme nous pouvons voir sur le côté droit, nous pouvons écrire un modèle HTML. Comme cela peut prendre en charge des expressions QGIS, nous vous encourageons à migrer votre "ancienne" configuration pour ajouter du HTML.
Cette nouveauté a été financée par le PNR Ballons des Vosges.
Navigation sur la carteEn raison de la transition, sous le capot, d'OpenLayers 2 vers OpenLayers 10, la transition entre les différents le niveau de zoom est désormais plus fluide que dans la version 3.7.
Dans 3.7, le choix dans Lizmap concernant la légende était de suivre exactement ce que faisait QGIS Bureautique lors d'un clic dans la légende sur les groupes, sous-groupes et couches.
Après quelques retours d'utilisateurs, nous avons introduit le double clic dans la légende pour basculer tous les éléments enfants.
Filtrage par attribut
Lorsqu'une couche dispose d'un filtrage attributaire sur les utilisateurs ou les groupes, il est désormais possible d'avoir une liste de valeurs séparées par des virgules dans le champ :
id name filter_field 1 one group_a,group_b 2 two group_b 3 three group_b,all 4 four all Cette nouvelle fonctionnalité a été financée par le département du Calvados.
Numérisation et relations au sein du projetPour les relations 1:n et n:m, lorsqu'elles sont dans une popup, les éléments enfants sont correctement placés à l'intérieur de la popup parent selon la configuration QGIS Glisser&Déposer.
Le même comportement existe lors de la modification d'une entité.
De nouveaux boutons pour ajouter des entités liées ont été ajoutés, par exemple dans la table attributaire ci-dessous :
Cette nouvelle fonctionnalité a été développée par Faunalia.
Lors de la numérisation, il y a un bouton Effacer tout.
PopupNous avons introduit un nouveau composant HTML
lizmap-features-tablepour avoir une liste compacte d'entités et les étiquettes d'une couche vecteur. Le Nom d'affichage (Display name) de QGIS est utilisé comme étiquette de l'entité : une expression peut être utilisée pour modifier son contenu, configuré dans l'onglet Info-bulle des propriétés de la couche vecteur de QGIS. Par exemple :CONCAT("quartiers_libquart", ' - ', "libsquart", ' (', to_int(area(@geometry)/10000), ' ha)')produira un texte comme
MONTPELLIER CENTRE - Les Aubes (85 ha)
Vous pouvez trouver plus d'informations sur la page dédiée sur GitHub sur la syntaxe de ce composant HTML.
Cette nouveauté a été financée par la ville d'Avignon.
AdministrationDans le panneau d'administration, sur la page Information serveur, similaire à la liste des extensions QGIS Serveur installées, on peut désormais retrouver la liste des modules Lizmap installés, avec sa version correspondante.
Concernant les extensions, nous avons ajouté un lien HTML vers la page d'accueil de l'extension, afin de vous guider vers quelques informations complémentaires. Cette dernière fonctionnalité viendra également sur les modules plus tard.
Chargement du JavaScript
Si un JavaScript génère une erreur lors du chargement de la carte, il existe désormais un bouton pour ouvrir temporairement la carte sans JavaScript complémentaire grâce au paramètre
no_user_defined_js=1dans l'URL. Cela vous permet de charger la carte et vérifiez si l'erreur provient d'un script complémentaire.En passant, nous avons également travaillé sur XSS. Ce travail a commencé il y a quelques versions (en 3.6), mais maintenant en 3.8, il n'est plus possible d'intégrer directement du code JavaScript dans l'info-bulle HTML de QGIS. Vous devez utiliser un fichier
Sous le capot*.jsdédié.La carte OpenLayers 10 est maintenant par-dessus la carte "historique" OpenLayers 2. Certains outils ont été migrés d'OpenLayers 2 vers OpenLayers 10, comme les popups et la localisation par surbrillance d'une couche. Par conséquent, cette version supprime à nouveau certaines dépendances d'OpenLayers 2.
Vous devrez peut-être adapter des scripts JavaScript complémentaires définis par l'utilisateur pour dessiner vos couches OpenLayers par-dessus la carte OpenLayers 10, par exemple.
Documentation sur le codeDepuis la version 3.7, de nombreuses refactorisations de code ont été effectuées du côté JavaScript et PHP. Nous pouvons désormais fournir une documentation HTML sur ces deux langages. Elles sont disponibles sur docs.3liz.org par exemple pour PHP ou pour JavaScript.
Nous vous recommandons fortement d'utiliser la nouvelle API JavaScript lors de l'écriture d'un script JavaScript complémentaire personnalisé.
TéléchargementVous pouvez télécharger le dernier zip sur notre page des sorties.
Pensez à installer la dernière version
3.8.X(et non pas3.8.0par exemple)Vous pouvez également consulter la liste des modifications complètes ("changelog") de la version 3.8.0, en anglais.
ModulesÀ la date du 15 octobre 2024, voici la liste des modules qui ont été mis à jour pour 3.8 :

3liz: Release of Lizmap Web Client 3.8
sur Planet OSGeoLizmap Web Client 3.83Liz is pleased to announce the release of Lizmap Web Client 3.8, the new major version of the application.
Funders
Pre-requirements and installation
It is now required to have a minimum QGIS server 3.28. However, we highly recommend using the latest LTR version, i.e. version 3.34. Check the QGIS roadmap.
To take full advantage of this version 3.8, don't forget to update your Lizmap plugin in QGIS desktop. We've written an article dedicated to this version.
Features Single tile request for all layersUntil version 3.7, Lizmap Web Client was doing one HTTP request to QGIS server per visible layer.
Now, thanks to Faunalia which contributed to the source code, Lizmap Web Client can make a single HTTP request
GetMapto QGIS Server for all visible layers (except for layers having a cache enabled).Both methods have strengths and weaknesses. This new option in the plugin, can be very useful for heavy projects.
Quick tip which is available on latest 3.7 as well, it's now possible to disable the automatic permalink with the checkbox.
SnappingWhen snapping is enabled on a layer, the user can now select from the web interface on which layer to snap on.
This new feature have been developed by Faunalia.
TooltipThe "Tooltip" feature in Lizmap Web Client got a great improvement in this latest version. Before, on the left side of the screenshot, you could only select one field to display while hovering a feature in the web browser. Now, as we can see on the right side, we can write an HTML template. We can support QGIS expression, se we encourage you to migrate your "old" configuration to add some nice HTML.
This new feature have been funded by PNR Ballons des Vosges.
Map viewerDue to the transition, under the hood, from OpenLayers 2 to OpenLayers 10, the map transition between different zoom level is now smoother than in the 3.7 release.
In 3.7, the choice in Lizmap about the legend was to follow exactly what QGIS Desktop is doing when clicking in the legend about groups, subgroups and layers.
After some user feedbacks, we could introduce the double click in the legend to toggle all child items.
Attribute filterWhen a layer has an attribute filtering about user or groupes, it's now possible to have a comma separated list of values in the field :
id name filter_field 1 one group_a,group_b 2 two group_b 3 three group_b,all 4 four all This new feature have been funded by Calvados province.
Digitizing and relations within the projectFor both 1:n and n:m relations, when displayed in a popup, the child items are correctly placed inside the parent popup according to the QGIS Drag&Drop configuration relations have been improved.
The same behavior exists when editing a feature.
New buttons to add linked features have been added, for instance in the attribute table below :
This new feature have been developed by Faunalia.
When digitizing, there is a button Erase all.
PopupWe have introduced a new HTML component
lizmap-features-tableto have a nice compact list of vector layer features and labels.The QGIS Display name is used as the feature label: an expression can be used to tweak its content, configured in the Tooltip tab of the QGIS vector layer properties. For example:
CONCAT("quartiers_libquart", ' - ', "libsquart", ' (', to_int(area(@geometry)/10000), ' ha)')will produce a text like
MONTPELLIER CENTRE - Les Aubes (85 ha)You can find more information on the dedicated page on GitHub about the syntax of this HTML component.
This new feature have been funded by Avignon city.
AdministrationIn the administration panel, on the Server information page, similar to the list of QGIS Server plugins installed, we can now find the list of Lizmap modules installed with its own version.
About the plugins, we have added an HTML link to the plugin home page, we can lead you to some information about the plugin itself. This latest feature will come as well on modules later.
JavaScript loadingIf a JavaScript raises an error while loading the map, there is now a button to temporarily open the map without additional user JavaScript script thanks to the flag in the
no_user_defined_js=1. This allows you to ty the map and check if the error come from an additional script.Side note, we have also worked on XSS. This work started a few version ago (in 3.6), but now in 3.8, it's not possible to embed JavaScript code into QGIS HTML maptip directly. You must use a dedicated
Under the hood*.jsfile.The OpenLayers 10 map is now on top on the legacy OpenLayers 2 map. Some tools were migrated from OpenLayers 2 to OpenLayers 10, like popup and locate by layer highlight. Therefore, this version removes again some OpenLayers 2 dependencies.
You might need to adapt some additional user defined JavaScript to draw your OpenLayers layers on top of the OpenLayers 10 map for instance.
Documentation about the codeSince version 3.7, a lot of code refactoring was done on the JavaScript and PHP side. Therefore, we can now provide an HTML documentation about these two languages. Both are available on docs.3liz.org for instance for PHP or for JavaScript.
We strongly recommend you to use the new JavaScript API when writing custom additional JavaScript script.
JavascriptDue to the work which have been done during the legend or other features in Lizmap, some previous Javascript script might not work anymore and need to be adapted.
DownloadYou can download the latest zip on our releases page.
Do not forget to install the latest
3.8.X(and not3.8.0for instance).You can also check the full changelog of version 3.8.0.
ModulesAs of October 15th 2024, this is the list of modules which have been released for 3.8 :
Other modules are work-in-progress.
We hope you will enjoy this new version ?

Sean Gillies: Running again
sur Planet OSGeoAfter I gave up on The Bear 100 and Black Squirrel in August, I stopped running for 6 weeks to let my Achilles tendonitis subside. I quit using the stair stepper and elliptical machines at the gym, too. My only activities were bike commuting, yoga, weight lifting, and a weekly "HIIT the water" class. I've joked about aquasizing, but have really been getting into this class. The instructor is gung ho, the regulars are friendly, and it's a good, low impact, workout. I'm going to keep doing it this fall and winter, for sure.
On the 20th of September I went for a flat 2 mile run at Pineridge Open Space. It felt great to run outdoors on dirt, and I didn't feel any worse afterwards. I did another easy, flat trail run 4 days later. This week I did two 3.5 mile runs on trails and another session on an elliptical trainer. 2 hours in all. I'm going to try to increase to 3 hours a week by the end of the year.
I'm grateful to be able to run again. With some luck, 2025 could be a good year.

Sean Gillies: Rasterio 1.4.0
sur Planet OSGeoA month ago I wrote a long-ish post about Fiona 1.10.0. I'll try to keep this one shorter. Rasterio 1.4.0 has three main changes: Python openers, detailed error chaining, and a new statistics API.
Python openers can connect filesystems implemented in Python, like fsspec or tiledb.vfs, to GDAL's own virtual filesystem machinery. In most cases, you should reply on GDAL's built-in virtual filesystem handlers. On the other hand, if you have unique or proprietary data access protocols, then Rasterio's new openers may be useful.
Often enough, I want more visibility into the errors that occur during GDAL I/O functions. I'd like to see all the errors, not just the last one. So, I've implemented Python-like chaining of GDAL errors. It's not perfectly analogous, because we don't have frames for GDAL code like we do for Python, but look at the kind of details you can get now:
>>> src.read() rasterio._err.CPLE_AppDefinedError: TIFFFillTile:Read error at row 512, col 0, tile 3; got 38232 bytes, expected 47086 The above exception was the direct cause of the following exception: rasterio._err.CPLE_AppDefinedError: TIFFReadEncodedTile() failed. The above exception was the direct cause of the following exception: Traceback (most recent call last): File "rasterio/_io.pyx", line 968, in rasterio._io.DatasetReaderBase._read io_multi_band(self._hds, 0, xoff, yoff, width, height, out, indexes_arr, resampling=resampling) File "rasterio/_io.pyx", line 207, in rasterio._io.io_multi_band with stack_errors() as checker: File "rasterio/_io.pyx", line 213, in rasterio._io.io_multi_band return checker.exc_wrap_int(retval) File "rasterio/_err.pyx", line 307, in rasterio._err.StackChecker.exc_wrap_int raise last rasterio._err.CPLE_AppDefinedError: /app/tests/data/corrupt.tif, band 1: IReadBlock failed at X offset 1, Y offset 1: TIFFReadEncodedTile() failed. The above exception was the direct cause of the following exception: Traceback (most recent call last): File "<console>", line 1, in <module> File "rasterio/_io.pyx", line 650, in rasterio._io.DatasetReaderBase.read out = self._read(indexes, out, window, dtype, resampling=resampling) File "rasterio/_io.pyx", line 971, in rasterio._io.DatasetReaderBase._read raise RasterioIOError("Read or write failed. See context for details.") from cplerr rasterio.errors.RasterioIOError: Read or write failed. See context for details.
Lastly, the flawed, multimodal
statistics()method of datasets has been deprecated and is replaced by new, simplerstats(),clear_stats(), andupdate_stats()methods.Rasterio 1.4.0 remains limited to "classical" rasters, those with a handful of bands or channels all of the same type. For hyperspectral data cubes and the like, you should use h5py, xarray, or other emerging software. I'm quite interested in working on new software in that area, but I'd like to do so without any classical raster legacy.

Oslandia: New release for QField : 3.4 “Ebo”
sur Planet OSGeoOslandia is the main partner of OPENGIS.ch around QField. We are proud today to forward the announcement of the new QField release 3.4 “Ebo”.
Main highlights
A new geofencing framework has landed, enabling users to configure QField behaviors in relation to geofenced areas and user positioning. Geofenced areas are defined at the project-level and shaped by polygons from a chosen vector layer. The three available geofencing behaviours in this new release are:
- Alert user when inside an area polygon;
- Alert user when outside all defined area polygons and
- Inform the user when entering and leaving an area polygons.
In addition to being alerted or informed, users can also prevent digitizing of features when being alerted by the first or second behaviour. The configuration of this functionality is done in QGIS using QFieldSync.
Pro tip: geofencing settings are embedded within projects, which means it is easy to deploy these constraints to a team of field workers through QFieldCloud. Thanks Terrex Seismic for sponsoring this functionality.
QField now offers users access to a brand new processing toolbox containing over a dozen algorithms for manipulating digitized geometries directly in the field. As with many parts of QField, this feature relies on QGIS’ core library, namely its processing framework and the numerous, well-maintained algorithms it comes with.
The algorithms exposed in QField unlock many useful functionalities for refining geometries, including orthogonalization, smoothing, buffering, rotation, affine transformation, etc. As users configure algorithms’ parameters, a grey preview of the output will be visible as an overlay on top of the map canvas.
To reach the processing toolbox in QField, select one or more features by long-pressing on them in the features list, open the 3-dot menu and click on the process selected feature(s) action. Are you excited about this one? Send your thanks to the National Land Survey of Finland, who’s support made this a reality.
QField’s camera has gained support for customized ratio and resolution of photos, as well as the ability to stamp details – date and time as well as location details – onto captured photos. In fact, QField’s own camera has received so much attention in the last few releases that it was decided to make it the default one. On supported platforms, users can switch to their OS camera by disabling the native camera option found at the bottom of the QField settings’ general tab.
Wait, there’s moreThere are plenty more improvements packed into this release from project variables editing using a revamped variables editor through to integration of QField documentation help in the search bar and the ability to search cloud project lists. Read the full 3.4 changelog to know more, and enjoy the release!

QGIS Blog: Plugin Update – September, 2024
sur Planet OSGeoIn September a total of 20 new plugins were published in the QGIS plugin repository.
HighlightIn the last month some AI-related plugins became available for users, namely IntelliGeo and TreeEyed, which in addition to the increasing number of tools, greatly contribute for the adaptation of QGIS to current and future needs, showcasing it as one of the best options for beginners and experts alike to conduct a number of geospatial analyses.
As stated by their authors, with IntelliGeo there’s a chat interface where users can detail their requests, and the output is either a PyQGIS code or a graphical processing model, which can in turn be executed directly in QGIS.
As for the TreeEyed plugin, its main objective is the monitoring of trees by generating vector and raster datasets from high resolution RGB imagery.
Overview
Here follows the quick overview in reverse chronological order. If any of the names or short descriptions catches your attention, you can find the direct link to the plugin page in the table below:
Project Setup Sets up a QGIS project to my personal specs. Continuous Network Analysis (Processing) Processing plugin that adds several scripts to assist in decision making and validation of line-type vector networks by generating inconsistencies, further expanding the “Network Analysis” tool. Oslandia Official plugin for Oslandia customers. Reach Enables the use of real transit time as a spatial predicate for selects and joins. Data Clock Polar plot of seasonal data. QGIS Light QGIS made simple – a light user interface for core GIS functions. Attribute Searcher A minimalistic plugin to search for values in attributes quick and easy. Topo Maps ????????Generate Topographic Maps. IntelliGeo IntelliGeo is QGIS plugin that facilitates interaction with Large Language Models in QGIS environment. CartAGen Cartographic generalization. RiverBankErosionAndAccretion This plugin calculates the erosion and accretion along a river’s course. VectorStats Plugin for descriptive and statistical analysis of vectors, with chart generation. Jilin1Info(2023) 2023???50cm???????????? Historique Parcelle Historique des parcelles (cadastre français). String Writer Writes QGIS layers to Surpac string file format. TreeEyed TreeEyed is a QGIS plugin for tree monitoring using AI. SHP Buddy Quickly create shapefiles for breeding experiments. TEKSI Wastewater TEKSI Wastewater plugin to manage wastewater networks. KGR Finder By simply drawing polygons or clicking on existing polygons, this extension makes it possible to download data from OpenStreetMap (OSM) or the iDAI.gazetteer and display it on the map, including all existing attributes. The plugin is designed so that other services can also be easily integrated in the future. layer_style_master This QGIS plugin copies symbology, labels, and rendering settings from one layer to multiple other layers. -

Free and Open Source GIS Ramblings: LLM-based spatial analysis assistants for QGIS
sur Planet OSGeoAfter the initial ChatGPT hype in 2023 (when we saw the first LLM-backed QGIS plugins, e.g. QChatGPT and QGPT Agent), there has been a notable slump in new development. As far as I can tell, none of the early plugins are actively maintained anymore. They were nice tech demos but with limited utility.
However, in the last month, I saw two new approaches for combining LLMs with QGIS that I want to share in this post:
IntelliGeo plugin: generating PyQGIS scripts or graphical modelsAt the QGIS User Conference in Bratislava, I had the pleasure to attend the “Large Language Models and GIS” workshop presented by Gustavo Garcia and Zehao Lu from the the University of Twente. There, they presented the IntelliGeo Plugin which enables the automatic generation of PyQGIS scripts and graphical models.
The workshop was packed. After we installed all dependencies and the plugin, it was exciting to test the graphical model generation capabilities. During the workshop, we used OpenAI’s API but the readme also mentions support for Cohere.
I was surprised to learn that even simple graphical models are actually pretty large files. This makes it very challenging to generate and/or modify models because they take up a big part of the LLM’s context window. Therefore, I expect that the PyQGIS script generation will be easier to achieve. But, of course, model generation would be even more impressive and useful since models are easier to edit for most users than code.
Image source: https://github.com/MahdiFarnaghi/intelli_geo
ChatGeoAI: chat with PyQGIS
ChatGeoAI is an approach presented in Mansourian, A.; Oucheikh, R. (2024). ChatGeoAI: Enabling Geospatial Analysis for Public through Natural Language, with Large Language Models. ISPRS Int. J. Geo-Inf., 13, 348.
It uses a fine-tuned Llama 2 model in combination with spaCy for entity recognition and WorldKG ontology to write PyQGIS code that can perform a variety of different geospatial analysis tasks on OpenStreetMap data.
The paper is very interesting, describing the LLM fine-tuning, integration with QGIS, and evaluation of the generated code using different metrics. However, as far as I can tell, the tool is not publicly available and, therefore, cannot be tested.

Have you heard of an alidade? I hadn’t until Walter Schwartz sent me these pics.
He said “Behold the ingenious alidade, a surveying instrument here used as a fire finder. This one is displayed at the Cole Land Transportation Museum in Bangor, Maine. Forest rangers used these atop fire towers to report the distance and, in conjunction with another tower, the coordinates of fires. The map on this table covers an approximately 25 mile diameter (40 KM) inclusive of Augusta to Rockport Maine. The user viewed through a rectangular slot on one upright and rotated the metal structure to view the fire. Some tables were on slides so that the view would not be obstructed by parts of the tower structure. GPS and cameras solve the same problem today. “
Well who knew that? I found this great explanation of the alidade.

Paul Ramsey: Cancer 12
sur Planet OSGeoBack to entry 1
I was glancing at the New York Times and saw that Catherine, the Princess of Wales, had released an update on her treatment. And I thought, “wow, I hope she’s doing well”. And then I thought, “wow, I bet she gets a lot of positive affirmation and support from all kinds of people”.
I mean, she’s a princess.
Even us non-princesses, we need support too, and I have to say that I have been blown away by how kind the people around me in my life have been. And also how kind the other folks who I have never really talked with before have been.
I try to thank my wife as often as I can. It is hard not to feel like a burden when I am, objectively, a burden, no matter how much she avers I am not. I am still not fully well (for reasons), and I really want to be the person she married, a helpful full partner. It is frustrating to still be taking more than I’m giving.
From writing about my experience here, I have heard from other cancer survivors, and other folks who have travelled the particular path of colorectal cancer treatment. Some of them I knew from meetings and events, some from their own footprint on the internet, some of them were new to me. But they were all kind and supportive and it really helped, in the dark and down times.
From my work on the University of Victoria Board of Governors, I have come to know a lot of people in the community there, and they were so kind to me when I shared my diagnosis. My fellow board members stepped in and took on the tasks I have not been able to do the past few months, and the members of the executive and their teams were so generous in sending their well-wishes.
And finally, my employers at Crunchy Data were the best. Like above and beyond. When I told them the news they just said “take as much time as you need and get better”. And they held to that. My family doctor asked “do you need me to write you a letter for your employer” and I said “no, they’re good”, and he said, “wow! don’t see that very often”. You don’t. I’m so glad Crunchy Data is still small enough that it can be run ethically by ethical people. Not having to worry about employment on top of all the other worries that a cancer diagnosis brings, that was a huge gift, and not one I will soon forget.
I think people (and Canadians to a fault, but probably people in general) worry about imposing, that communicating their good thoughts and prayers could be just another thing for the cancer patient to deal with, and my personal experience was: no, it wasn’t. Saying “thanks, I appreciate it” takes almost no energy, and the boost of hearing from someone is real. I think as long as the patient doesn’t sweat it, as long as they recognize that “ackknowledged! thanks!” is a sufficient response, it’s all great.
Fortunately, I am not a princess, so the volume was not insuperable. Anyways, thank you to everyone who reached out over the past 6 months, and also to all those who just read and nodded, and maybe shared with a friend, maybe got someone to take a trip to the gastroenterologist for a colonoscopy.
Talk to you all again soon, inshala.
