This interactive map of French dams displays their locations as points across the country, with each point linking to a detailed information page. The visualization is built from a GeoJSON FeatureCollection of dam properties, including height, reservoir volume, river, and owner. The data was cleaned and enriched using shell scripting and the `jq` command-line tool, with the final map likely rendered using a library such as Leaflet or Mapbox. The code shows the use of `ogrinfo` and `ogr2ogr` for geospatial data processing and SQL queries to transform the attributes.

Gist b3d6991a9d7ab3de6f7f13e7ed38e097

This map shows the municipal arrondissements of Lyon and Marseille in France, with each district colored according to its population. The visualization loads GeoJSON data describing the polygon boundaries of each arrondissement and uses the ogr2ogr library to convert the shapefile data. The interactive display, viewed through GeoJSON.io, renders the geographic features using standard web mapping tools and displays the population values stored in each polygon's properties when the user clicks or hovers over a district.

This example demonstrates how to convert tabular JSON data containing longitude and latitude fields into a GeoJSON FeatureCollection using the command-line tool jq, making it ready for map-based visualization. The dataset covers digital mediation locations in the Auvergne-Rhône-Alpes region of France, sourced from data.gouv.fr. The transformation maps each original record into a GeoJSON Feature, preserving properties like name, address, services, and accessibility conditions, while constructing Point geometry from the coordinate pair. The code includes a preview image showing the resulting spatial distribution of these locations, though the visualization itself uses no specific JavaScript mapping library or framework beyond the jq conversion process.

A map of the Paris region displays IGN-F/Geoportail basemap tiles using Leaflet 1.9.2. The code constructs a `L.tileLayer` that requests WMTS tiles from the `wxs.ign.fr` service, specifying the `GEOGRAPHICALGRIDSYSTEMS.PLANIGNV2` layer with a 256-pixel tile size and zoom levels 0–18. Tile coordinates are inserted into the URL via `{z}`, `{y}`, and `{x}` placeholders. The map is centered on coordinates [48.845, 2.424] at zoom 10 using `L.map().setView`.

This example tracks the availability and licensing of the French IGN’s BD TOPO® departmental datasets by organizing URLs for both December 2021 and March 2021 releases. It shows a structured index of geographic data files, with each entry linking to a specific departmental Shapefile resource. The visualization uses a data-driven list format, likely rendered with JavaScript’s `fetch` to parse the provided CSV or JSON and display the sorted URLs. It highlights the variation in resource IDs across departments and time periods, emphasizing the dataset’s scope without mapping or spatial rendering.

A Leaflet map centered on France displays a circular buffer polygon around a point at coordinates (2.18, 46). The example uses proj4js and the reproject library to convert the point from WGS84 to EPSG:3857, then applies jsts.io.GeoJSONReader to read the geometry and create a 40,000-meter buffer via the jsts buffer method. After writing the buffered geometry back to GeoJSON, it reprojects to WGS84 and renders the result as a Leaflet GeoJSON layer on OpenStreetMap tiles, with a scale control and a marker at (0,0).

Récupération geolocalisation EHPAD 57

This example visualizes the geographic distribution of EHPAD (nursing homes) in the Moselle department (57) of France, displaying each facility as a point on a map. The data is retrieved from a public government API and converted to GeoJSON format using `jq` command-line tools for filtering and restructuring. The visualization is built with the Vue framework, rendering the geographic points to show facility locations, with additional property information such as name, city, and legal status included for reference. The map uses standard GeoJSON `Point` features to represent each facility's coordinates.

This map visualizes the locations of tobacco retailers in the Ain department of France, with each point geocoded from a public directory of licensed shops. A marker shows the position of every vendor, with details available for each location. The visualization likely uses a geographic rendering library such as D3.js with `d3.geoPath` to display the map, while the underlying data comes from the `annuaire-des-debits-de-tabac-deb.geocoded.geojson` file, which contains coordinates and metadata for each establishment.

Gist 207d4ca5cb9d116c81752a3c17d6c24b

This map visualizes Burkina Faso’s administrative polygons, likely distinguishing regions by color or stroke. It uses D3.js to load and render the GeoJSON features with `d3.geoPath` and a geographic projection, displaying the country’s boundaries as vector shapes. The code references a two-polygon dataset and appears suited for choropleth or boundary mapping, with the rendering handled directly via SVG or Canvas.
