- ShapeFile
- .zip file containing at least:
- .shp: shape format; the geometries
- .shx: shape index
- .dbf: attributes/properties

- .json file
- .geojson file
For points, the supported format files are:
- .zip file
- Make sure files are at the root of the file (which means that there is no folder inside the zip file)
