Maps that start the moment you drop in a file.

DropMaps is a browser-based GIS workspace for desktop and mobile. Drag in your layers, add open data around them, then style, edit and share.

See it in action

Map it. Style it. Share it.

Drop in any layer

GeoJSON, KML, Shapefiles, geotagged photos, aerial imagery, geodatabases and more. Drag them onto the map and they open straight away, ready to explore.

Open data in a click

Buildings, roads and places from Overture, fresh Sentinel-2 imagery with NDVI, and public map servers. Mix them with your own files.

Maps in 3D

Colour buildings by their floor counts and raise them into a 3D city, turn points into 3D hexbins, and drop in city models over terrain.

Show me how

Style by value

Colour by category or with graduated ramps, add labels, and tidy every class at once. The map updates as you go.

Show me how

Edit & measure precisely

Reshape features with snapping to neighbouring corners and edges, draw new ones, and measure true geodesic distances and areas.

Show me how

Live filters & charts

Drag a slider or tick a category and the map and dashboard charts update together. Charts can show "x of y" figures.

Ready for the field

Make a map offline ready before you lose signal, then keep recording: forms with pick lists, GPS stamps and edit tracking, synced when you are back.

Share a live map

Publish a link anyone can open: a branded, read-only viewer with popups, legend and charts. No account needed to view.

Why DropMaps

A full GIS, with nothing to set up

Drop in any format

Shapefiles, File Geodatabase (.gdb.zip), KML/KMZ, GeoJSON, CSV, TopoJSON, GeoTIFF/COG, GeoPDF 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.

Save & share

Publish a map, not a file

A free account syncs across devices, backs up to the cloud and publishes a live map anyone can open — no account needed to view. Go Pro when you need more room.

Local-first, always free

The full editor — import, edit and export every format — runs in your browser. Nothing leaves your machine unless you choose to sync.

Share a public link

On every plan, free included: share a map with anyone via a link — a branded, read-only viewer with optional splash, expiry and view stats. Pro adds password-protected links.

Cloud sync & storage

Back up and sync your maps across devices on any plan — 100 MB free, 5 GB on Pro, and more in $1/mo USD per-10 GB packs whenever you need it.
