Geometry Type: Range
A RANGE is a buffer around another geometry. You might use a range to specify:
- A polygon within 5 miles of a business location.
- A polygon of the area within 100 meters of (and including) a county.
Syntax
RANGE(<distance>[<units>] <geometry>)
where distance is an integer and geometry is either WKT or a feature ID.
To specify a polygon within 3 kilometers of a point:
RANGE(3km POINT(-122 37))
