This example demonstrates how to select cadastral parcels from the IGN Cadastre API based on a drawn polygon’s extent. It shows the process of converting a GeoJSON polygon into an encoded URL parameter, then sending a GET request via Bash with `jq` or Python with `urllib.parse` and `urllib.request`. The API returns parcel geometries, which are saved as a GeoJSON file. The code also warns against using overly complex or overly large geometries due to URL length limits and server load.

This map visualizes a geospatial polygon from a GeoJSON file, outlining a specific land parcel or boundary area with high coordinate precision. The shape is rendered as a MultiPolygon, with vertices tracing a detailed, irregular perimeter typical of cadastral or survey data. The minimal, line-only representation emphasizes the geometry’s raw form, highlighting the boundary’s complexity and the spatial distribution of the region without additional contextual layers. The visualization focuses on the raw geographic footprint, making the coordinate data the primary visual element.

This example demonstrates streaming merge of two French cadastral parcel GeoJSON files into a single unified feature collection, output as a continuous JSON stream to standard output. It shows how to combine multiple geospatial datasets without loading them entirely into memory. The code uses the `geojson-stream` library for parsing and stringifying GeoJSON features, Node.js `fs.createReadStream` for file input, and the `zlib` module to decompress gzipped source files. Data originates from the Etalab cadastre dataset, with separate scripts handling zipped and unzipped input files.

GDAL VSICURL tests to remote BDTOPO Geopackage France

This example tests GDAL’s VSICURL virtual file system by streaming a remote GeoPackage of French administrative data, specifically focusing on mairie (town hall) geometries. It demonstrates two ogr2ogr commands that query the BDTOPO dataset using SQL joins to extract mairie footprints as multipolygons and their centroids as points, converting them to GeoJSON with EPSG:4326. The visualization shows how both polygon boundaries and point locations are derived from the same remote source, highlighting the ability to perform spatial SQL operations directly on cloud-hosted vector data without local downloads.

This example curates a set of GeoJSON-based specifications and extensions, organizing them by how they add keys, use multiple files, or serialize for streaming. It lists linked resources such as geojson-t, geocodejson-spec, geojson-ld, and the OGC Features API, alongside STAC and Mapbox simplestyle. It also covers the IMDF format for indoor data and the GeoJSON Text Sequences proposal, presenting a structured reference rather than a rendered map or interactive chart, with no code libraries or visualization APIs involved.

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.

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.

Get area stats for parcelles and batiments for each parcelle

This example maps French cadastral data for the commune 91114, calculating the built surface area of buildings (batiments) on each land parcel (parcelle). It uses DuckDB’s spatial SQL functions—`ST_intersects`, `ST_intersection`, and `ST_Area`—to query a remote GeoParquet file from data.gouv.fr, then aggregates results with a `LEFT JOIN` to include parcels without buildings. The final query outputs a CSV of per-parcelle statistics, including total building footprint and parcel geometry attributes.

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.
