Geobuf (Protobuf-encoded GeoJSON)

Open Beta

.pbf · application/x-protobuf

Geobuf is a compact binary packing of GeoJSON on Protocol Buffers, created at Mapbox (Vladimir Agafonkin, 2015). It encodes the same objects as GeoJSON but typically 6–8x smaller thanks to varint, coordinate delta encoding, and a key dictionary; decoding returns an equivalent GeoJSON losslessly. It is a transport layer for mobile maps, edge CDN caches, and IndexedDB storage, not an analytical format. Our exporter builds a FeatureCollection from the OSM layers and encodes it into real protobuf .pbf with 6-digit precision (~0.1 m). Important: the format is honest — if encoding fails the export errors out, we do NOT substitute gzipped GeoJSON under a .pbf name.

ಪ್ರಮುಖ ವೈಶಿಷ್ಟ್ಯಗಳು

✓Binary packing of GeoJSON on Protocol Buffers, typically 6–8x smaller

✓Lossless: decoding returns an equivalent GeoJSON

✓Default coordinate precision of 6 digits (~0.1 m)

✓geobuf decoders for JavaScript and Python (Leaflet, Mapbox GL, D3)

✓Honest guarantee: real protobuf or an error, never a substitution

Geobuf ಫಾರ್ಮ್ಯಾಟ್ ಬಗ್ಗೆ

Geobuf solves one problem: the same GeoJSON, but many times smaller. Instead of text — Protocol Buffers; instead of repeating property names — a dictionary of keys; instead of full coordinates — the differences between neighboring points, written as variable-length numbers. The meaning of the data does not change, only the packing does.

This is a transport format. It is taken when data has to be delivered: into a mobile app over a weak network, onto a CDN node, into a browser's offline storage. Computing statistics or editing features in it is awkward — for that it is first decoded back into GeoJSON.

The file contains a single FeatureCollection with all the selected layers, encoded as genuine protobuf. Coordinates are rounded to six decimal places, which is about ten centimeters on the ground — more than enough for city-level detail. OpenStreetMap attributes are preserved.

There is no substitution: if the encoding fails, the export ends with an error. Handing you a gzipped GeoJSON under a .pbf extension would be easier, but such a file would not decode with the geobuf library — and so would be useless.

Geobuf ನಕ್ಷೆಗಳನ್ನು ಯಾರು ಬಳಸುತ್ತಾರೆ

🏗

Delivering vector data to a mobile app over a slow network

A compact parcel instead of a heavy GeoJSON — the difference is especially noticeable on mobile internet.

💻

Caching OSM selections on an edge CDN at a smaller size

Fewer bytes on every request to the cache: cheaper traffic and a faster response.

📊

Storing offline data in browser IndexedDB in compact form

The data sits packed in the browser's memory and is unpacked as needed.

🎨

Backing up GeoJSON snapshots 6–8x smaller without data loss

The same set of features in a file many times smaller, and decoding returns the original GeoJSON without any loss.

ರಫ್ತಿನ ನಂತರ ಹೇಗೆ ತೆರೆಯುವುದು

JavaScript — npm install geobuf pbf, then geobuf.decode(new Pbf(buffer)) returns ready GeoJSON that you can hand straight to Leaflet or Mapbox GL.
Python — pip install geobuf, then geobuf.decode(open("map.pbf", "rb").read()); after that it is ordinary GeoJSON work or loading into GeoPandas.
A mobile app — the file goes into the resources or is pulled from the server: decoding takes a fraction of a second, and the traffic is several times smaller.
Offline in the browser — the decoded result is convenient to keep in IndexedDB and redraw the map with no network.
Just to take a look — decode it into GeoJSON and drag it onto geojson.io: no viewer will show the .pbf itself.
