This example automates the bulk download of France’s urban planning WFS data from the Géoportail de l’Urbanisme, specifically extracting the GPKG files. It shows how to list available remote directories via `lftp` over SFTP, identify the latest dated export, and mirror the chosen folder with parallel transfers. The workflow uses shell commands with `timeout`, `ssh`, and `lftp` to handle authentication and file retrieval. It relies on public credentials and a documented PDF manual, making the process reproducible for users needing recent, structured land-use datasets.

Download data from WFS using GDAL Python bindings

This example shows how to download vector data from a WFS (Web Feature Service) endpoint using GDAL’s Python bindings. It demonstrates bulk download of a full layer, plus filtered extracts by bounding box via the `-spat` option, and outputs to GeoPackage, CSV, and GeoJSON formats. The code explicitly configures WFS paging with `OGR_WFS_PAGING_ALLOWED` and `OGR_WFS_PAGE_SIZE`, and uses `gdal.OpenEx` and `gdal.VectorTranslate` to fetch data from the Géoportail WFS service. A separate call requests GeoJSON output directly through the service’s `outputFormat=json` parameter.

Un peu laxiste sur les droits

This example demonstrates how an FTP directory from the French IGN geospatial agency can be served over HTTPS by mounting it as a local filesystem. The visualization shows a browsable file listing generated by an Nginx `autoindex` directive, which exposes the contents of a `curlftpfs`-mounted remote FTP server. The code relies on `curlftpfs` to mount the FTP source (`ftp://Iris_GE_ext:…@ftp3.ign.fr`) with `allow_other` and permissive permissions, and on Nginx’s `alias` and `autoindex` to render the directory tree. The interface lists downloadable geospatial datasets (e.g., IRIS-GE shapefiles) without requiring users to install an FTP client.

Export DVF geolocalisées en Geoparquet

This example converts French land-registry transaction data (DVF) from compressed CSV files into a single spatially-indexed GeoParquet file. It downloads yearly datasets from data.gouv.fr, loads them into a DuckDB database, and creates a point geometry for each transaction before exporting with a Hilbert-curve spatial ordering. The script leverages DuckDB’s spatial extension, the `ST_Point` and `ST_Hilbert` functions, and parquet compression via zstd.

Gist 2bd25e856943977444bac9a5fd8c6408

This example shows a QGIS workflow for automatically populating the application with WMS, WMTS, and WFS service connections from the French IGN geoservices portal. The script scrapes the portal’s documentation page to find a CSV file containing service metadata, parses it using the `csv` module, and deduplicates entries via Python dictionaries. It then defines functions to add or remove connections in QGIS’s settings using `QgsSettings`, configuring parameters like URLs, versions, and axis orientation. The code demonstrates a practical approach to batch-importing OGC web services into a desktop GIS environment.

Lien Adresse et parcelles

This example shows the relationship between French addresses and land parcels, producing flat CSV files per department and for the whole country from the IGN BAN PLUS dataset. The workflow uses a bash pipeline combining Python with `xml.etree.ElementTree` to fix VRT files, GDAL’s `ogr2ogr` and `ogrinfo` for data conversion and indexing, `jq` to parse layer names, and `xsv` to concatenate departmental rows into a nationwide file. Results are gzip-compressed and organized into `france` and `departements` directories.

Leaflet WMS

This example shows a map centered on a region in France, displaying both urban areas from a French government WMS layer alongside a French statistical data layer, with a scale bar. Built with the Leaflet JavaScript library, it combines OpenStreetMap tiles with two Web Map Service (WMS) layers. The first WMS source, accessed via a proxy from `data.europa.eu`, uses `L.WMS.source` and `source.getLayer("Tache_urbaine_1980_R43")`, while the second uses `L.tileLayer.wms` to load INSEE income data from an IGN endpoint.

Exemples de consommation de DVF via parquet et Duckdb

This example demonstrates how to extract and filter French property transaction data (DVF) from a cloud-hosted Parquet file using DuckDB's SQL engine, then export the filtered results as GeoJSON for specific geographic areas. It shows three distinct query scopes: a single commune (Nantes), a multi-commune agglomeration, and a department-level export. The workflow relies on DuckDB's `INSTALL spatial` and `LOAD spatial` extensions, which enable reading the Parquet file directly from the `data.gouv.fr` URL. The `COPY` command with `FORMAT gdal` and `DRIVER 'GeoJSON'` handles the conversion, while explicit type casting (e.g., `::DOUBLE`) ensures correct numeric fields like `valeur_fonciere` and coordinates (longitude/latitude), and preserves the geometry column for spatial output.

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.
