Hi all, could anyone help me with the below query? I'm trying to find the geometries from a table (ch04.newpoint) which intersect the raster (ch04.dumprastval).
However I can't seem to get it to work! Thanks. SELECT CAST((gval).val As integer) AS val, ST_Union((gval).geom) As geom FROM ( SELECT ST_Intersection( ST_Clip(rast,ST_Envelope(buf.geom)), 1, buf.geom ) As gval FROM ch04.dumprastval INNER JOIN ( SELECT ST_Buffer( ST_GeomFromText(geom,4326) FROM ch04.newpoint ON ST_Intersects(rast,geom) ) As foo GROUP BY (gval).val ORDER BY (gval).val; This email and any attachments are confidential and intended solely for the use of the addressee and may contain information which is covered by legal, professional or other privilege.
