Download Building Footprints for Any Area

Draw a box around a village, ward or site and download every building mapped there, in any format. No account, no file to bring — just an area on a map.

This tool sends the area you draw. Only the corner coordinates of your box go to the data servers — never a file of yours, here or anywhere on this site.

Where to get the buildings from

Detected from satellite imagery, so almost every village in India is covered.

Use a boundary file

Drop a village or ward boundary

Only its outer extent is used. The file itself stays on your machine.

Why this matters here

Older Indian survey and revenue records sit on the Everest spheroid, not WGS 84. Treating one as the other puts everything a few hundred metres out — enough to move a plot boundary onto a neighbour.

Indian systems included

Kalianpur 1880, 1937 and 1975, the India zone grids, UTM zones 42N to 47N on both WGS 84 and Indian datums, and the WGS 84 state systems.

Bulk paste

Paste a column straight out of a spreadsheet. Anything after the first two values is carried through as a label, and the result downloads as CSV.

Nothing leaves your device

The arithmetic runs in your browser with proj4. No coordinate is transmitted, logged or stored anywhere.

Frequently asked questions

What exactly leaves my machine?

The four corner coordinates of the area you draw, sent to OpenStreetMap's public Overpass servers so they can return what is inside. That is the whole of it. No file of yours is sent here or anywhere else on this site, there is no account, and there is no server of ours in the path — the request goes from your browser straight to OpenStreetMap.

Where does the data come from?

OpenStreetMap, mapped by volunteers over twenty years. It is the same data behind a great many maps you already use. Nothing here is generated by a model or guessed at.

My village has no buildings in it.

Then nobody has mapped them yet. Coverage is uneven in a way that surprises people: a town may be complete while the village beside it is empty. That is a gap in the map, not a fault in the tool, and anyone can fill it — OpenStreetMap is editable by you.

Can I use this data in my work?

Yes, including commercially, under the Open Database Licence. The condition is attribution: anything you publish from it must credit OpenStreetMap contributors. That is a licence term, not a courtesy, and the same obligation flows to whoever you pass it on to.

Is it accurate enough for a survey?

No, and it is not meant to be. These are volunteer-traced outlines from imagery, useful as a base to check and correct against the ground. For anything legal or measured, they are a starting point and nothing more.

Why is the area limited?

The servers are run and funded by volunteers. Capping the area keeps this site from becoming a burden on them, which is the only reason the service is free for anyone. Run several smaller areas rather than one large one.

What formats can I download?

All of them — Shapefile, KML, KMZ, GeoJSON, GeoPackage, CSV, Excel, DXF, TopoJSON and SVG. The conversion happens in your browser using the same code as the rest of the site.
