Working with GIS data isn’t easy. That’s why TileMill automates as much as possible for you – sharing data between projects, downloading and unzipping shapefiles, autodetecting projections, indexing SQLite databases – so that you can focus on making beautiful maps.

File formats and databases

TileMill can read from a wide range of popular file formats and databases: ESRI Shapefile, KML, GeoJSON, GeoTIFF, PostGIS, and SQLite.

Raster support

Show satellite terrain data or make use of your DIY weather balloon aerial photography with TileMill’s raster image support.

Feature inspection

With a built-in data inspector, you can see details about every lake, country, or road from your datasource.
