Feature Info API for OpenStreetMap

Attempt to create an API to get information about OSM features around a location. The current goal is to create a function that mimics the same output as the existing feature info function on the official OSM website. Find the source code of the existing function here.

Setup

Tested on Linux and WSL:

# download sample data (or use your own)
wget -O data/sample.pbf https://download.geofabrik.de/europe/andorra-latest.osm.pbf

# [optional] shut down existing compose stack
docker compose down --volumes --remove-orphans

# start services
docker compose up -d --build

# load data into db
docker compose run --rm osm2pgsql \
  --slim \
  --output=flex \
  --style=/data/flex_style.lua \
  --prefix=raw \
  /data/sample.pbf

# add function to DB
docker compose exec postgres psql -f /data/query_function.sql

Demo client can be accessed via http://localhost:4173/.

Replication can be executed like this:

# replication init
docker compose run --rm osm2pgsql replication init \
 --verbose \
 --prefix=raw \
 --osm-file=/data/sample.pbf

# replication update
docker compose run --rm osm2pgsql replication update \
  --prefix=raw \
  --verbose
