This file for the selected area contains:
- Water
Geometry by layer
- Water — table rows with WKT geometry (Polygon)

How to use WKT for Netherlands
- PostGIS — paste the lines as they are: INSERT ...
- Python — from shapely import wkt, then wkt.loads(line) line by line, skipping the lines that begin with two hyphens.
- QGIS — the QuickWKT plugin pastes geometry from the clipboard onto a temporary layer; for a full-fledged layer it is easier to download GeoJSON right away.

FAQ: WKT for Netherlands
What is WKT?
WKT (Well-Known Text) is a text representation of geometric objects per the OGC standard.
Can I import WKT into PostGIS?
Yes, via ST_GeomFromText() or ogr2ogr.
Are names and tags preserved?
No, geometry only: one shape per line. Take attributes in GeoJSON, GeoPackage or CSV, where the fields lie next to the WKT.
How do I tell which layer is which?
Layers are separated by comment lines like "-- layer: buildings": everything up to the next such comment belongs to the current layer. At the start of the file there are also comments with the bounding box of the area and the coordinate system.
Which coordinate system and what precision?
WGS84 (EPSG:4326), six decimal places — about ten centimeters on the ground. When loading into PostGIS, specify SRID 4326.
