    • sur OSGeo Announcements: [OSGeo-Announce] pgRouting graduates OSGeo Incubation

      Publié: 17 December 2024, 1:25pm CET

      [https:]]

      OSGeo welcomes pgRouting to its growing ecosystem of projects.

      OSGeo is pleased to announce that pgRouting has graduated from incubation and is now a full-fledged OSGeo project.

      pgRouting is an open-source extension in the PostGIS / PostgreSQL geospatial database, providing geospatial routing functionality.

      Graduating incubation includes fulfilling requirements for open community operation, a responsible project governance model, code provenance, and general good project operation. Graduation is the OSGeo seal of approval for a project and gives potential users and the community at large an added confidence in the viability and safety of the project.

      The pgRouitng Steering Committee collectively recognizes this as a big progressive step for the project.

      pgRouting has been an active contributor and participant to various open source initiatives inside and outside OSGeo such as FOSS4G, OSGeo Code Sprints, OGC Code Sprints, Joint OSGeo-OGC-ASF (Apache Software Foundation) Code Sprints, and Google Summer of Code.

      The pgRouitng PSC says, “We are excited about the future of the project within the OSGeo’s project ecosystem. We have been working to have a community of developers for the project sustainability. It is our honor to be an OSGeo project”.

      The pgRouting PSC would like to thank our mentor, Angelos Tzotsos, and the OSGeo Incubation Committee for their assistance during this Incubator process.

      Congratulations to the pgRouting community!

      About pgRouting

      pgRouting extends the PostGIS / PostgreSQL geospatial database to provide geospatial routing functionality. It is written in C++, C and SQL.

      It is an open source PostgreSQL extension which implements several graph algorithms.

      pgRouting library contains the following features:

      • All Pairs Shortest Path algorithms: Floyd-Warshall and Johnson’s Algorithm
      • Shortest Path and bi-directional algorithms: Dijkstra, A*
      • Graph components, analysis and contraction algorithms.
      • Traveling Sales Person
      • Graph components, analysis and contraction algorithms.
      • Shortest Path with turn restrictions

      pgRouting is able to process geospatial and non geospatial graphs.

      It’s processing extension execute a number of existing graph algorithms based on reliable software and libraries. It is written in such a way that gives the ability to hook a new graph algorithm in a clean way including the connection code to the database.

      The pgRouting functions are standardized in terms of parameter types and names, decreasing the learning curve of a user.

      pgRouting is very flexible with graph data input, in an inner SQL query and output with standardized column names, so you can process almost any kind of graph data stored in the database.

      Airlines around the world are reporting an increase in GPS spoofing and jamming incidents. GPS spoofing involves deliberately transmitting false GPS signals to trick a GPS receiver into believing it is in the wrong location. This manipulation can lead to navigation errors and pose significant security risks.GPS jamming, on the other hand, involves intentionally blocking or interfering with GPS

      Saw this election results map at the FDR Museum a couple of days before the 2024 US Election. This is what I would call an overwhelming vote for one candidate!

      The blurb says

      “FDR won a historic mandate in 1932.
      After three years of economic depression, Americans decisively rejected President Hoover and the ruling Republican Party. Roosevelt defeated Hoover in a landslide, and Democrats seized control of Congress for the first time in 16 years.
      They dominated the new Senate by an overwhelming margin of 60 to 35 and enjoyed a 310 to 117 majority in the House.
      Voters handed Franklin Roosevelt and the Democrats a blank check. Their only demand was action. What the public-and most Democratic leaders-did not know was what form that action would take.”

      You could reword this to fit today’s circumstances.

      Publié: 12 December 2024, 11:00am CET

      I spotted this map in Franklin Delano Roosevelt Museum, which had a special exhibition on FDR and Black African Americans.

      Redlining Map of Poughkeepsie, New York and its Suburbs, March 1938
      This redlining map of Poughkeepsie was among the hundreds of “Residential Security Maps” of urban areas created by the Home Owners’ Loan Corporation.

      The maps indicated mortgage lending risk by neighborhood type, including residential, commercial, and industrial areas. Residential districts were marked with different colors to indicate the level of risk in mortgage lending. Streets and neighborhoods that included minority (especially African American) and immigrant populations were often marked in RED as “Fourth Grade” or “Hazardous”— the riskiest category for federally insured homeowner loans. For example, in the BLUE area marked B3 on this map there is a small sliver of RED along Glenwood Avenue. Notes that accompany the map explain why: “Glenwood Avenue, which is shown in red, was an old Negro settlement before this area was built up.” Similarly, in the BLUE area marked B2 Pershing Avenue appears in RED. The mapmaker’s notes indicate: “Pershing Avenue (marked in red) has a number of negro families. Houses on this street are very poor and of little value.”

      Not a lot seems to have changed!

      WebGIS é uma tecnologia usada para exibir e analisar dados espaciais na Internet. Ele combina as vantagens da Internet e do GIS oferecendo um novo meio de acessar informações espaciais sem a necessidade de você possuir ou instalar um software GIS.

      A necessidade de divulgação de dados geoespaciais têm estimulado cada vez mais o uso de ferramentas WebGIS para apresentações interativas de mapas e de informações relacionadas por meio da internet.

      As soluções adotadas na apresentação destes mapas devem apresentar um equilíbrio entre facilidade de uso, riqueza de recursos para visualização e navegação entre os dados, e funcionalidades geoespaciais para pós processamento, características que devem ser adequadas para cada perfil de usuário que acessará o WebGIS.

      Se você e sua empresa possuem dados geoespaciais e querem disponibilizá-las na Web, o caminho natural para isso é o desenvolvimento de um WebGIS. Mas, se você não tiver uma equipe de TI, ou um especialista em desenvolvimento GIS, não se preocupe, a Geocursos pode te ajudar.

      Nossa experiência em GIS nos habilita a entregar soluções baseadas nessa tecnologia utilizando ferramentas open source de visualização geográfica aliada a soluções criativas para o seu negócio.

    • sur Sean Gillies: Late fall biking

      Publié: 8 December 2024, 4:55am CET

      I've decided to try to ride a bike for exercise more in 2025. Run harder, but run less, with more active recovery and low-intensity outings on a bike. At least until June, when I need to start building the running and hiking endurance that I will need in September.

      I got a new bike to make this more fun. It's a Rocky Mountain Solo C50 and I bought it from my favorite local bike shop, Drake Cycles, last Saturday. The first thing I did was pedal it from home up Spring Creek Trail to Pineridge Open Space and ride some laps around the pond. It sure beats riding my commuter bike on dirt and gravel. I haven't bought a new bike or any new bike components in 10 years. Electronic shifters feel like magic to me.

      A dark blue-green bike with wide drop handlebars leaning on an interpretive sign in a dry valley under and overcast sky.

      So far this week I've done two rides from the barn where we keep our horses while Bea has been doing her equestrian stuff. One at sunset and one at sunrise. I've been three miles east of the barn and seven miles north of the barn, following roads on the PLSS section grid.

      https://live.staticflickr.com/65535/54189616674_92bf31726f_b.jpg

      A dirt road at dusk, headlights of an approaching truck, and orange sunset glow behind the Rocky Mountains.

      In the neighborhood of the barn, the ground is completely free of snow and quite dry. Passing trucks raise medium density clouds of dust. There are scattered homes out here, and vehicles going to and fro periodically. There are large construction sites, too, which can mean a wave of large rigs pulling trailers.

      A rolling dirt road and brown grassland with snow-dusted mountains in the background.

      I've got a lot to learn about this kind of riding. The right tire pressure for road and trail conditions, for example, and how to get in and out of the drops smoothly. How to descend and corner safely, and how to survive washboard surfaces. Dressing, too. I'm riding at a low intensity and don't generate as much heat as I do when I run.

      One of my favorite things about riding further east is the panoramic views of the Front Range peaks. I can see Pikes Peak, Mount Evans, Longs Peak, and the Mummy Range, a span of 200 kilometers, from the top of every rise.

      At last, I'm less than 1% injured and am getting back into regular and productive running. We've had a long stretch of mild and dry weather here, which makes it easy to just lace up and go. I ran four times last week, including a nice hilly run in Lory State Park, and will run three times this week. Thursday I did some harder running and a bunch of strides for the first time since June.

      Some faint numbness lingers on my left quad, but my hip, butt, and leg are otherwise just fine. My doctor prescribed a course of prednisolone in early November to calm down my pinched nerve and that seemed to banish the last of my Achilles tendonitis as well. My right heel and calf haven't been pain-free in a long time. It's really nice to feel good.

      Publié: 5 December 2024, 1:00pm CET

      À medida que o mundo transita para um futuro energético mais limpo e sustentável, o papel dos Sistemas de Informação Geográfica (GIS) se tornou indispensável.

      O GIS nos permite enfrentar os desafios complexos do desenvolvimento de energia renovável com precisão e eficiência.

      Seja identificando os principais locais para fazendas solares, avaliando o potencial de energia eólica ou planejando infraestrutura hidrelétrica, o GIS fornece os insights espaciais necessários para tomar decisões informadas.

      Além do planejamento de projetos, o GIS oferece suporte a avaliações ambientais, mitiga riscos e ajuda a integrar energia renovável em redes elétricas, garantindo que esses desenvolvimentos sejam sustentáveis e resilientes.

      Ele também capacita provedores de energia e formuladores de políticas a envolver comunidades, reduzir emissões e enfrentar as mudanças climáticas de frente.

      Aqui estão 10 maneiras principais pelas quais o GIS está moldando o setor de energia renovável, promovendo inovação e impulsionando mudanças impactantes:

      ?Integração da Rede
      ?Avaliação de Recursos
      ?Avaliação de Impacto Ambiental
      ?Engajamento da Comunidade
      ?Análise de Risco
      ?Monitoramento e Manutenção
      ?Análise de Uso do Solo
      ?Planejamento de Infraestrutura Energética
      ?Mitigação de Mudanças Climáticas
      ?Mapeamento de Demanda Energética

      In the United States, a persistent and striking political divide is evident between urban and rural areas. High-density urban regions overwhelmingly tend to support Democratic candidates, while low-density rural areas lean Republican. This geographical polarization shapes the outcomes of elections and reflects broader cultural, economic, and ideological divisions. A compelling exploration

    • sur Free and Open Source GIS Ramblings: GeoParquet in QGIS – smaller & faster files for the win!

      Publié: 23 November 2024, 10:23pm CET

      tldr; Tired of working with large CSV files? Give GeoParquet a try!

      “Parquet is a powerful column-oriented data format, built from the ground up to as a modern alternative to CSV files.” [https:]]

      (Geo)Parquet is both smaller and faster than CSV. Additionally, (Geo)Parquet columns are typed. Text, numeric values, dates, geometries retain their data types. GeoParquet also stores CRS information and support in GIS solutions is growing.

      I’ll be giving a quick overview using AIS data in GeoPandas 1.0.1 (with pyarrow) and QGIS 3.38 (with GDAL 3.9.2).

      File size

      The example AIS dataset for this demo contains ~10 million rows with 22 columns. I’ve converted the original zipped CSV into GeoPackage and GeoParquet using GeoPandas to illustrate the huge difference in file size: ~470 MB for GeoParquet and zipped CSV, 1.6 GB for CSV, and a whopping 2.6 GB for GeoPackage:

      Reading performance

      Pandas and GeoPandas both support selective reading of files, i.e. we can specify the specific columns to be loaded. This does speed up reading, even from CSV files:

      Whole fileSelected columns
      CSV27.9 s13.1 s
      Geopackage2min 12s ?20.2 s
      GeoParquet7.2 s4.1 s

      Indeed, reading the whole GeoPackage is getting quite painful.

      Here’s the code I used for timing the read times:

      As you can see, these times include the creation of the GeoPandas.GeoDataFrame.

      If we don’t need a GeoDataFrame, we can read the files even faster:

      Non-spatial DataFrames

      GeoParquet files can be read by non-GIS tools, such as Pandas. This makes it easier to collaborate with people who may not be familiar with geospatial data stacks.

      And reading plain DataFrames is much faster than creating GeoDataFrames:

      But back to GIS …

      GeoParquet in QGIS

      In QGIS, GeoParquet files can be loaded like any other vector layer, thanks to GDAL:

      Loading the GeoParquet and GeoPackage files is pretty quick, especially if we zoom into a small region of interest (even though, unfortunately, it doesn’t seem possible to restrict the columns to further speed up loading). Loading the CSV, however, is pretty painful due to the lack of spatial indexing, which becomes apparent very quickly in the direct comparison:

      (You can see how slowly the red CSV points are rendering. I didn’t have the patience to include the whole process in the GIF.)

      As far as I can tell, my QGIS 3.38 ‘Grenoble’ does not support writing to or editing of GeoParquet files. So I’m limited to reading GeoParquet for now.

      However, seeing how much smaller GeoParquets are compared to GeoPackages (and also faster to write), I hope that we will soon get the option to export to GeoParquet.

      For now, I’ll start by converting my large CSV files to GeoParquet using GeoPandas.
