GeoProjectGeometry() is used to aggregate a geometry into an area and apply a projection.
Syntax:
GeoProjectGeometry(type, field_name)
Return data type: string
Arguments:
| Argument | Description |
|---|---|
| type | Projection type used in transforming the geometry of the map. This can take one of two values: 'unit', (default), which results in a 1:1 projection, or 'mercator', which uses the web Mercator projection. |
| field_name | A field or expression referring to a field containing the geometry to be represented. This could be either a point (or set of points) giving longitude and latitude, or an area. |
