 ## Supported Output Formats
 
-Databend supports three geospatial output formats—[WKT (Well-Known Text)](https://www.ogc.org/standards/sfa), [WKB (Well-Known Binary)](https://www.ogc.org/standards/sfa), and [GeoJSON](https://geojson.org/)—enabling compatibility with a wide range of geospatial applications and tools.
+Databend supports multiple geospatial output formats—[WKT (Well-Known Text)](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry), EWKT (Extended Well-Known Text), [WKB (Well-Known Binary)](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry#Well-known_binary), EWKB (Extended Well-Known Binary), and [GeoJSON](https://geojson.org/). EWKT and EWKB extend WKT and WKB by including an SRID (Spatial Reference System Identifier) to specify the coordinate reference system, e.g., `SRID=4326;POINT(-44.3 60.1)`.
