About PostGIS SQL
Map of Afar Region in PostGIS SQL — an export of real OpenStreetMap data for the selected area.
PostGIS SQL is a text SQL script that creates a table with a geometry column and fills it with data, ready to load into any PostgreSQL database with the PostGIS extension. It is a convenient way to hand an OSM selection to a team already on the PostgreSQL stack: apply the script and you immediately have a geometry table for queries through ST_* functions. Our exporter generates a self-contained .sql: CREATE TABLE with a geom column and attributes, then one INSERT per feature where geometry is given via ST_GeomFromText(WKT, SRID) (SRID 4326 by default). Multiple layers become separate tables, and values are escaped (SQL-injection safe). Honestly: this is a simple human-readable dump via ST_GeomFromText, not a binary pg_dump archive and not the full osm2pgsql schema with planet_osm tables and spatial indexes.

How to use PostGIS SQL for Afar Region
- psql — create the database, run CREATE EXTENSION postgis, then psql -d your_database -f dump.sql; the layer tables appear right away together with the indexes.
- DBeaver or pgAdmin — open the file as a script and run it as a whole, if working in a terminal is inconvenient.
- Before applying it — look through the beginning of the file: it shows which tables will be dropped and created anew.

FAQ: PostGIS SQL for Afar Region
Is this a pg_dump dump?
No. We generate a human-readable SQL script with CREATE TABLE and INSERT via ST_GeomFromText, applied through psql -f. It is not a binary custom-format pg_dump archive.
Will this be the osm2pgsql schema with planet_osm tables?
No. We create simple per-layer tables with a geom column and attributes. The full osm2pgsql schema (planet_osm_polygon/line/point/roads with GiST spatial indexes) is not reproduced here.
How do I apply the script?
Create a database with CREATE EXTENSION postgis, then psql -d your_db -f dump.sql. The geometry tables appear immediately, ready for ST_* queries.
Which coordinate system is the geometry in?
SRID 4326 (WGS84) by default. It is written into ST_GeomFromText and into the geometry column definition.
Are indexes created?
Yes, for every table the script adds a GiST spatial index on the geom column — queries by area work fast right after it is applied. Indexes on attribute fields you create yourself if you need them.
