GIS site analysis tool for designers
TOPOLUMA gives architects and landscape designers the GIS layers they need around a site without setting up QGIS: open data, your own files and the coordinate systems in one place.
What you get
- Open data
- OpenStreetMap buildings, roads, railways, water and vegetation; ESA WorldCover tree cover; terrain from Mapterhorn (Copernicus GLO-30 and national models).
- Your files
- Import DXF, GeoJSON, KML, KMZ and shapefiles. Choose WGS 84, a UTM zone, an EPSG code or a proj4 string; the system is guessed from the file first.
- Measurements
- Distance, path length, area and perimeter on the map; parcel sides, angles and the direction each side faces.
- Back to GIS
- Export GeoJSON in WGS 84, or DXF and IFC in UTM, so the work goes back into QGIS or ArcGIS.
How to do it
- Draw the area or import a file and set the area around it.
- Choose the layers and generate.
- Check the coordinate system of each imported file in Layers.
- Export the formats you need.
Limits to know
TOPOLUMA is not a full GIS: there is no attribute table editing, raster analysis or custom projections for output beyond local metres and UTM. More on the data and accuracy page.
