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 . 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
