Raw Data API is a set of high-performant APIs for transforming and exporting OpenStreetMap (OSM) data in different GIS file formats.

Fast: Built on top of FastAPI
OAUTH 2.0 Authentication with OpenStreetMap(OSM)
Multiple GIS formats support via GDAL's ogr2ogr - see table below for currently supported formats. Out of which , GeoJSON Follows Own Raw Data API conversion script
Formats Status Esri Shapefile ✔️ KML ✔️ Mbtiles ✔️ FlatGeoBuf ✔️ CSV ✔️ GeoPackage ✔️ PGDUMP ✔️ GeoJSON ✔️ Pmtiles ✔️ Geoparquet ✔️

Status Feature ✅ Yaml support for rawdatapi request ✅ Support for country exports ✅ Vector tiles support ✅ Tasking Manager exports support ✅ Export completeness information integration ✅ Independent exports link to be shared accross various stakeholders using hdx ⚙️ Metadata of exports such as no of features / total length etc ⚙️ p-code support for exports ⚙️ yaml request connection with export tool ⚙️ Migration to generic cron jobs from hdx jobs Improvements in data exports using h3 index research Raw Data Backend Upgrade

Raw Data API consists of two elements:

A backend database, tools, and scripts: used to import OSM data into a specific database structure and keep it updated.
An API that is used to serve data from the backend database.

Raw Data API can be installed through docker or locally on your computer.

To install with docker see docker installation.
To install locally, see local installation.

Setup the necessary configurations for Raw Data API from configurations. Setup config.txt in project root or include your env variables in .env

Confirm that Authetication works
1. Hit the /auth/login/ endpoint
2. Hit the url returned on the response
3. You will get an access_token
4. You can use the access_token in all endpoints that requires authentication.
5. To check token pass token in /auth/me/. It should return your OpenStreetMap (OSM) profile
Try extracting some data:

You can use the /raw-data/current-snapshot/ endpoint with the following input to check both authentication, database connection and download the export:

curl -d '{"geometry":{"type":"Polygon","coordinates":[[[83.96919250488281,28.194446860487773],[83.99751663208006,28.194446860487773],   [83.99751663208006,28.214869548073377],[83.96919250488281,28.214869548073377],[83.96919250488281,28.194446860487773]]]}}' -H 'Content-Type: application/json'   http://127.0.0.1:8000/v2/raw-data/current-snapshot/

We use sozip optimization while we zip the files , SOZip makes it possible to access large compressed files directly from a .zip file without prior decompression. It is not a new file format, but a profile of the existing ZIP format, done in a fully backward compatible way. ZIP readers that are non-SOZip aware can read a SOZip-enabled file normally and ignore the extended features that support efficient seek capability. Learn more about it in attached link

Raw Data API uses pytest for tests, navigate to the root directory and install package in editable mode:

At this point you should have PostgreSQL + PostGIS extension enabled on your computer, now run Pytest:

Running individual tests

py.test -k test function name
