adistance |
a FLOAT for the distance from the geometry value to the buffer. |
Returns an ST_Geometry value.
All ST_Geometry types
Note: This method can be called on 3D geometries (those that include z coordinates). However, the z coordinate is dropped, and only x and y coordinates are returned.
The adistance argument is measured in the linear units of measure in the spatial reference system of the ST_Geometry value.
