Osm2pgsql

Osm2pgsql is a tool that converts OpenStreetMap data, which contains detailed geographic information about roads, buildings, and other features, into a format suitable for use in geographic databases like PostgreSQL with PostGIS. It processes raw map data and organizes it into structured tables, enabling efficient querying and visualization for map applications. Essentially, it acts as a translator, transforming large, complex map data into a usable and accessible format for developers and GIS professionals.
