FlatGeobuf (FGB)

Open Beta

.fgb · application/flatgeobuf

FlatGeobuf ni umbizo la binari lenye utendaji wa hali ya juu kwa data za kijiografia lililojengwa juu ya FlatBuffers. Limeboreshwa kwa mtiririko wa kazi wa wingu-asili na maombi ya masafa ya HTTP. Faharasa ya anga iliyojengwa ndani kwa ufikiaji wa papo hapo wa kipande chochote cha ramani.

Kuhusu Muundo wa FlatGeobuf

FlatGeobuf is a binary vector data format based on FlatBuffers, which appeared in 2018 as "a shapefile for the cloud". Features are laid out in the file sequentially, with a spatial index written alongside, so the fragment you need is read directly, without parsing the whole file.

The main feature is working over HTTP range requests: you can put the file in object storage or on static hosting and read from the browser only the features that fall into the current screen. You don't have to stand up a geoserver for the sake of one layer.

All the selected layers are merged into a single .fgb, and every feature keeps a _layer attribute with the name of its source layer — it takes the export apart again into roads, buildings, water and greenery. OpenStreetMap attributes are preserved, coordinates are WGS84 (EPSG:4326), and the spatial index is written automatically.

Compared to GeoJSON the file is noticeably smaller and reads faster; compared to a shapefile there are no limits on field name length, encoding or size. There is one price to pay: you cannot look at such a file in a text editor.

Nani Hutumia Ramani za FlatGeobuf

🏗

GIS ya wingu

The layer sits in object storage and is read directly, with no database and no geoserver.

💻

Utiririshaji wa data za kijiografia

The client fetches only the features in the visible area — thanks to the index and range requests.

📊

Ramani za wavuti

A vector source for MapLibre, deck.gl and Leaflet that loads faster than an equivalent GeoJSON.

🎨

Seti kubwa za data

Hundreds of thousands of features in one file, without the shapefile's limits on size and field names.

🗺

Usanifu wa serverless

A static file instead of an API: nothing to stand up and nothing to maintain.

Jinsi ya Kufungua Baada ya Kuhamisha

QGIS 3.16 and newer (free) — drag the .fgb into the program window; the format is read by the standard GDAL, no plugins needed.
Python — geopandas.read_file("map.fgb"); a filter on the _layer column splits the export back into the source layers.
A web map — the flatgeobuf library for JavaScript reads the file by URL and loads only the visible area; it works with Leaflet, MapLibre and deck.gl.
ogr2ogr — ogr2ogr -f GPKG out.gpkg map.fgb converts it into GeoPackage, GeoJSON or PostGIS.
Putting it in the cloud — when publishing to S3 or static hosting, enable CORS and Range request support, and the client will fetch only the fragments it needs.
