This example recreates the command-line tool mapshaper-info using the gdal-async library to inspect a GeoJSON TopoJSON file containing German administrative regions. It downloads the dataset from GitHub, then prints layer metadata including geometry type, record count, bounding box, and coordinate reference system, followed by a formatted table of attribute names and their first values. The script uses the got library for streaming downloads and the pipeline function from stream/promises to handle the file writing asynchronously.

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 visualization displays a QGIS project containing world map layers—countries, states, provinces, and disputed borders—from the bundled `world_map.gpkg` GeoPackage, alongside JSON-derived point layers for contributors, hackfests, and user groups. Using the QGIS Python API, the script loads each vector layer via `QgsVectorLayer` with OGR drivers, adds them to the project through `QgsProject.instance().addMapLayers`, and enables a retro canvas style by setting `iface.mapCanvas().setProperty("retro", True)` before refreshing. The example demonstrates procedural map composition from built-in geodata files.

Load GTFS as GPKG with GDAL 3.7

This example demonstrates converting an IDFM GTFS transit feed into a GeoPackage database using GDAL’s new GTFS driver. The Bash script first checks that GDAL 3.7 is installed, then uses `ogrinfo` with `-json` to list all available layers. For each layer, it runs `ogr2ogr` with the GeoPackage format, appending layers incrementally with the `-update` flag. The source data is loaded directly from a URL via `/vsicurl/`, and the script allows customizing input and output names through environment variables.

This example displays a map of Thuringian districts using topological vector data. It renders the region by loading a TopoJSON file and converting it to GeoJSON with the `topojson` library. The single multipolygon is drawn as an SVG path using `d3.geo.path()` with a default Mercator projection, showing the administrative boundaries in a straightforward black outline against a blank background.

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.

Play with gdal.vectorTranslate in Node.js

This example demonstrates a complete geospatial data processing pipeline using the Node.js `gdal-async` library. It downloads a Natural Earth countries dataset, extracts the ZIP archive, and converts the shapefile to GeoPackage format with `gdal.vectorTranslate`, then transforms the GeoPackage into GeoJSON. The script uses the `got` library for HTTP streaming with progress reporting and `adm-zip` for extraction. This showcases how GDAL's vector translation capabilities can be invoked programmatically in a Node.js environment for format conversion between common geospatial file types.

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.

This example renders a world map from a TopoJSON file containing land polygons. The visualization uses D3.js to project and draw the geographic data onto a canvas, with the `d3.geoPath` function handling the polygon outlines. The code loads the `Land.json` file, which stores the geometry in TopoJSON format, and prepares it for display using D3’s geographic projection utilities. The map shows the basic landmasses of the world as simple filled shapes, with no additional thematic data or interaction applied to the polygons.
