WKT Viewer – Frequently Asked Questions

What is a WKT Viewer?

A WKT Viewer renders Well-Known Text geometry strings as visual shapes on an interactive map, making it easy to inspect and verify spatial data without writing any code.

Can I view multiple geometries at once?

Yes — paste a GEOMETRYCOLLECTION to display multiple geometry objects simultaneously on the map.

Does it support EWKT with SRID prefix?

Yes, EWKT strings with SRID prefixes (e.g. SRID=4326;POLYGON(...)) are parsed and rendered correctly.

Is there a size limit on the WKT input?

No hard limit is enforced in the browser. Very large geometries with millions of vertices may slow down rendering on lower-end devices.

What is the difference between the WKT Viewer and the WKT Editor?

The WKT Viewer is read-only — it displays your WKT on a map. The WKT Editor adds full editing, drawing and export capabilities.
