Parse well known text as geometry

Supported in: Batch, Streaming

Converts well-known text (WKT) string to geometry logical type. Invalid WKT input will be returned as null. Optionally supply a source coordinate system identifier to convert from the source coordinate system to WGS 84 if the WKT is not in WGS 84 already.

Expression categories: Geospatial

Declared arguments

• Expression: Valid well-known text as a string.
  Expression<String>
• optional Source coordinate system: Optional coordinate system identifier if the well-known text is not WGS 84. Formatted as "authority". For example, UTM zone 18N could be identified by EPSG:32618.
  Literal<String>

Output type: Geometry
