Hi All,
I need to generate a bounding box geometry around a point and St_Expands
seem to be heading in the right direction. However, I need to create it to
different dimensions in each axis. Currently, as I understand it
ST_Expands(point_geom, 10) will return me a bounding box extended 10 geometry
units in the x, y and z axis. I would like to be able to do
ST_Expands(point_geom, 10, 8, 6) where it extends 10 units in X, 8 in Y and 6
in Z. Can anyone recommend how this might be done with the current PostGIS 1.5
functions toolset, I cannot thing of one at present, otherwise can anyone point
me in the right direction to a tutorial on how I might extend this function
from scratch in the current source code and re-compile it locally.
Thanks in advance,
Paul
