TerraLab gets map data into QGIS from a conversation. Ask for buildings, roads, addresses, land use, waterways, transit stops or protected areas around any place, see them on an interactive map with a street or aerial view, and download them as Shapefile, GeoJSON, KML or CSV that open directly in QGIS. Data comes from Overture Maps and OpenStreetMap. Convert files and coordinates: open a GeoJSON, KML, KMZ, GPX, zipped Shapefile, CSV or WKT file, check it on a map and convert it. Convert coordinates between decimal degrees, DMS, UTM, MGRS, Lambert 93 and EPSG codes, with the recommended local CRS for your project. Put a single place or a list of up to 100 addresses on a map and export the points. Terrain: elevations, profiles and contour lines anywhere in the world from Copernicus DEM. In France, find the cadastral parcel and the local urban plan (PLU) zone at an address, from the official cadastre and Géoportail de l'Urbanisme open data; owner names and sale prices are never returned. No account or sign-in is needed. Every answer names its sources and licences (OpenStreetMap, Overture Maps, Copernicus DEM, ESA WorldCover Sentinel-2 imagery, IGN and DGFiP open data), and every download includes its licence. Limits: extracts up to 20,000 features and 200 km² for buildings (larger for other layers), contour lines up to about 10 x 10 km, files up to 50 MB and lists up to 100 addresses. Elevation comes from a 30 m surface model that includes buildings and trees. Results are approximate and not for navigation, surveying or legal boundaries.
