Why DropMaps

A full GIS, with nothing to set up

📥

Drop in any format

Shapefiles, KML/KMZ, GeoJSON, CSV, TopoJSON, GeoTIFF/COG and PMTiles — drag them straight onto the map.

⚡

Runs in your browser

DuckDB-WASM and MapLibre do the heavy lifting client-side. No upload, no server round-trip, no install.

🎨

Style & edit

Symbolise layers, edit attributes, draw and reshape geometry, and organise everything into layer groups.

🛰️

Big rasters, no sweat

Cloud-Optimized GeoTIFFs and PMTiles stream via HTTP range reads — view large imagery without downloading it all.
