"I Ain’t Afraid of No Map" - Ghost Mappers

The ghost of the notorious highwayman Dick Turpin is said to visit his uncle’s grave in St Mary the Virgin Church in London. He is just one of three spirits believed to haunt the churchyard, which is also visited by a grey lady searching for her dead husband, and a skeletal figure pushing a cart with an empty coffin - forever hunting for his wife, whose body was stolen by grave robbers.This is

Mapping the Wikipedia Rabbit Hole

All of us have, at some time or another, fallen down a Wikipedia rabbit hole. You begin with the noble intention of looking up a single topic, only to find yourself tumbling through an unplanned journey of blue hyperlinks.Start with Geradus Mercator, follow a link to Antwerp, hop over to the Tomorrowland festival, and before you know it you’re reading about Metallica. What began

Back to Black

Back to Black Today’s #30DayMapChallenge is Black. For this challenge I decided to create a map that makes use of and demonstrates one of MapLibre’s most powerful features: the ability to programmatically restyle map layers in real time. My Back to Black map itself isn’t designed to be practical or analytical in itself - it’s simply an exploration of how to change a map's style in

Deadly Rivers in the Sky

The Washington Post reports that rising global temperatures are leading to ever more extreme rainfall around the world. Since the 1990s global heating has dramatically increased the amount and movement of water vapor in the Earth’s atmosphere , in some regions by more than 15 percent. These “invisible rivers” of vapor act like atmospheric fire hoses: and when they encounter disturbances such as

Mapping the Property Tax Divide

Most U.S. municipalities rely on property taxes to fund public services. This means that the amount of taxable wealth within each city boundary can create stark inequalities - even between neighboring communities. Wealthy municipalities are able to raise far more revenue than places with lower-value property, allowing affluent enclaves to spend generously while less affluent communities -

Oslandia: New in QGIS 3.40 : CMYK Support

Credits : Bru-nO (Pixabay Content License)

Thanks to funding from the Bordeaux Metropolis, I had the chance to work on CMYK (Cyan Magenta Yellow blacK) support in QGIS. The metropolis’ goal is to remove the last barrier preventing their complete migration from ArcGIS to QGIS.

The developments are now complete and will be available in QGIS version 3.40, scheduled for release in October 2024, before becoming the next LTR in February 2025. It should be noted, however, that CMYK support will only be complete in QGIS versions built with Qt 6 (still unofficial version) for reasons explained in the article. On Windows, this version can currently only be installed using OSGeo4W (qgis-qt6-dev version).

Oslandia: [Customer Testimonial] Nicolas Godet, ISL Engineering

A hydraulic engineer by training, Nicolas Godet has been working at ISL Ingénierie for just over seven years and holds the position of hydraulic project manager (flood risk, hydraulic structure safety), deputy director of the Saint-Jean-de-Luz facility, and QGIS (and GIS in general) advisor.

He discusses the implementation of QDT and the associated methodology for deploying QGIS across ISL’s IT infrastructure.

What are the objectives of the collaboration?

Before I took charge of deploying QGIS at ISL, it was a bit of a mess: no one had the same version, the same plugins, or the same practices.
Following the switch to QGIS3, there was a desire to standardize the QGIS fleet at ISL to have the same version, the same plugin base, and preconfigured profiles.

An initial, semi-homemade solution was implemented in 2022, but it proved difficult to maintain.

Fernando Quadro: Como alterar o contextPath no GeoServer

Em ambientes onde o GeoServer é executado dentro de um contêiner Apache Tomcat, pode surgir a necessidade de alterar o caminho de contexto (contextPath) da aplicação, ou seja, o endereço pelo qual o serviço será acessado.

Essa modificação é comum em cenários de ambientes compartilhados, integrações com outros sistemas, migrações de infraestrutura ou simplesmente para padronizar URLs (por exemplo, mudar de /geoserver para /geoserver-admin ou /gis).

No entanto, antes de fazer essa alteração, é importante revisar as configurações do Tomcat, especialmente no arquivo server.xml, e entender a diferença entre deploy automático e manual, garantindo que o GeoServer seja publicado corretamente no novo contexto.

Ian Turton's Blog: Repair, Reuse and Recycle

How I created a spare monitor

I’m big on reuse, repair and recycling which is one of the reasons I volunteer at Glasgow Repair Cafe – I blame being exposed to “Stig of the Dump” at an impressionable age. As a result I struggle to throw out broken things let alone things that still work. However, space limitations mean that I do occasionally have to tidy out some stuff. I discovered that I have way too many old laptops that will come in useful sometime recently. So I installed a light weight linux on two of them and donated one of them to the repair café (where we have several laptops that really should be retired as they lack some keys), the other one is an old ThinkPad which I will use in my workshop/garage so that I don’t get sawdust in my work laptop.

Durante años fuimos profundizando en la metodología y aprendiendo de la experiencia de aplicarla en la vida real.
