map-data-for-a-place

Gets open map data for any place in the world as a map, a count and a file that opens in QGIS. Covers administrative boundaries (countries, regions, departments, districts), building footprints, roads, railways, transit stops, addresses, points of interest such as schools, pharmacies or shops, land use, rivers and lakes, power lines and protected areas. Use when someone asks for GIS data, a layer, a shapefile or GeoJSON, OpenStreetMap or Overture data for an area, or simply where or how many of something there are in a place, for example all schools in Kisumu, the departments of Côte d'Ivoire or the buildings of Porto-Vecchio.

places-files-and-coordinates

Puts addresses, coordinates or a GIS file on a map and converts them. Covers geocoding one address or a list of up to 100 (pasted or CSV) and the address at a point, opening and checking GeoJSON, KML, KMZ, GPX, zipped Shapefile, CSV or WKT files, converting between these formats, converting coordinates between decimal degrees, DMS, UTM, MGRS, Lambert 93 and EPSG codes, and choosing the right CRS for QGIS. Use when someone wants a list of addresses or clients on a map, the coordinates of an address, a KML turned into a Shapefile, a GPX opened, coordinates converted, or data that lands in the wrong place.

site-study

Builds a first look at a site or plot anywhere in the world before a project such as a house, an extension, a solar farm, a shop or a purchase. Combines the terrain (altitude and slope), what lies around it (buildings, roads, rivers and lakes, land use, protected areas, power lines, transit) and, in France, the cadastral parcel and the local urban plan (PLU) zone. Use when someone asks what is on or around an address or a plot, whether a site is flat, near water or in a protected area, or asks about a parcel, its section and number, cadastre, zoning or PLU in France.

terrain-and-elevation

Gives terrain information anywhere in the world from the Copernicus 30 m elevation model. Covers the altitude of places, an elevation profile between points or along a route with total ascent and descent, a DEM clipped to an area as a GeoTIFF with a hillshade and a slope map, contour lines (topographic lines, courbes de niveau) as a file for QGIS or any GIS, and how steep or flat an area is. Use when someone asks for a DEM, SRTM, a relief or terrain model, elevation, altitude, height above sea level, contours, slope, a hiking or cycling profile, or the topography of a place, for example "I need the DEM of Milan" or "contour lines around Chamonix every 10 m".
