This example shows how to query the French administrative geography API (geo.api.gouv.fr) for commune data, specifically searching for “Montpellier” and printing each matching commune’s name, code, department, SIREN, EPCI, and population to the console. It uses the Java 11 `java.net.http.HttpClient` to send an asynchronous request, `HttpRequest` and `HttpResponse` to handle the HTTP/2 call, and the external JSON-java library (`org.json.JSONArray` and `JSONObject`) to parse the JSON response. The code demonstrates a minimal, non-visual data-fetching workflow rather than a graphical chart.

Java certificate issues recipe + basic java demo

This example demonstrates a basic Java 11 HTTP client that retrieves dataset metadata from the data.gouv.fr API, parsing the JSON response to extract and print the URLs of all resources. The code uses `java.net.http.HttpClient`, `HttpRequest`, and `HttpResponse` for the asynchronous request, alongside the `org.json` library for JSON parsing. The accompanying recipe addresses a "PKIX path building failed" error by downloading the site’s certificate via `InstallCert.java` and importing it into the JDK 19 keystore using `keytool`, which is necessary for the HTTPS connection to succeed.

Gist c8b3e33ae90180e985646e1ef4876dfe

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.

Generation GeoJSON des mairies avec code INSEE

This example generates a GeoJSON file of French town halls (mairies) with their INSEE commune codes, distinguishing principal towns from associated communes. It uses `ogr2ogr` with an SQLite dialect to join commune boundaries with their chief-town points from the IGN ADMIN-EXPRESS dataset, applying `PointOnSurface` as a fallback when no official point exists. The resulting output is written with RFC 7946 compliance for modern web mapping. The script downloads a 7z archive and extracts the necessary shapefiles before performing the spatial join.

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.

Gist 96068363e74b4c1c148c55aad9ab0cf4

This example demonstrates client-side reprojection of GeoJSON geometries from a source CRS to WGS84 using the Proj4js library. It fetches a French “quartiers prioritaires” dataset encoded in EPSG:2154 and transforms its Point, LineString, Polygon, and Multi* geometries via custom functions that recursively map coordinates through a proj4 transformer. It also tests a second transformation from EPSG:4326 to EPSG:3857 on sample geometries, logging converted coordinates to the console. The code relies on proj4.defs, proj4(...).forward, and the fetch API.

Query remote Geoparquet in browser

This example demonstrates querying a remote GeoParquet file directly from a web browser using DuckDB-Wasm. The interactive map displays French priority neighborhoods (QPVs) and identifies which one contains a specific geographic point (2.389798, 48.909514). It uses DuckDB-Wasm’s SQL engine with the spatial extension to run an `ST_contains` query, filtering results by geometric intersection. The workflow converts the matched polygons to GeoJSON via the GDAL driver and exports them as a downloadable file. The dataset was prepared from a government GeoJSON source using DuckDB and gpio utilities.

Gist 349fc7fda8932252cbcb4ee8a0b605c8

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.

Compiler un EPT (établissements publics territoriaux)/des EPT

This example generates GeoJSON files for the Établissements Publics Territoriaux (EPT) of the Greater Paris metropolis. It shows two outputs: a single EPT boundary dissolved from its constituent communes, and a comprehensive file covering all EPTs. The single-EPT workflow uses a bash script with `wget` to fetch commune geometries from the geo.api.gouv.fr API, then applies `jq` to merge them and `mapshaper` with the `-dissolve` operation. The generalized version uses Python with `urllib`, `pandas`, and `geopandas` to read an INSEE Excel spreadsheet, join commune codes to geometries from Etalab’s contours-administratifs dataset, and dissolve by EPT attributes.
