## What it is
osm2pgsql is a command-line ETL tool that imports OpenStreetMap data in OSM, PBF, and O5M formats into a PostgreSQL/PostGIS database. It supports flexible Lua-configured table layouts, incremental updates from change files and replication diffs, and scales from small extracts to full planet imports.

## Use cases
- import openstreetmap data into postgresql
- load osm pbf files into postgis
- set up a database for rendering map tiles
- keep an osm database up to date with replication diffs
- run a nominatim geocoder backend
- do geospatial analysis on osm data with postgis
- create a poi map from openstreetmap data
- export osm data to gis formats

## When to choose
- you need OSM data in PostgreSQL/PostGIS for rendering, geocoding, or analysis
- you want configurable table layouts via Lua scripting
- you need incremental updates from OSM change files
- you need to scale from a city extract to a full planet import

## When to avoid
- you need a general-purpose ETL tool for non-OSM data
- you want a GUI-based import tool
- your target database is not PostgreSQL/PostGIS
- you only need to view OSM data without a database

## Facets
