WKT Editor – Frequently Asked Questions

What is Well-Known Text (WKT)?

Well-Known Text (WKT) is an OGC standard text format for representing vector geometry objects such as points, lines, polygons and collections. It is widely used in GIS databases, spatial APIs and geometry libraries.

Does this WKT editor work offline?

Yes — all geometry parsing and map rendering happen entirely in your browser. No data is sent to a server.

What WKT geometry types are supported?

POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON and GEOMETRYCOLLECTION, including their Z (3D) and M (measured) variants.

Can I paste EWKT with an SRID prefix?

Yes, EWKT strings such as SRID=4326;POINT(30 10) are recognised automatically. The SRID prefix is stripped before rendering.

How do I export my geometry?

Click the Export button in the toolbar. Supported formats are GeoJSON, Shapefile (.zip), KML and CSV.
