Is it possible to do spatial operations with PHP MapScript? Currently, if I
want to do intersection between two shapes, I have to write the following
postgis queries in my map file:
DATA 'the_geom from (
select h.gid, intersection(k.the_geom, h.the_geom) as the_geom
FROM test.jawabali_konservasi k INNER JOIN
test.jawabali_hutanlindung h
ON
(k.the_geom && h.the_geom AND intersects(k.the_geom, h.the_geom))
) as foo using unique gid using srid=-1'
Is it possible to do such thing on the fly with MapScript?
And if spatial operations are possible with MapScript, is it possible to
intersect a particular color range of a raster (which is defined in mapfile as
CLASS) with polygons?
Many thanks,
