"I am attempting to intersect a vector dataset of building polygons with a 3-Band Thermal tiff to produce a dataset that shows the thermal readings for each polygon."
If I took the 3 band jpeg of this raster and used ST_AsTiff to convert it to a single band tiff would this calculation be valid? How could I place this into the query? SELECT gid, ST_Intersection(geom, rast, 1) FROM clip_build, nclheat WHERE ST_Intersects(rast, geom) any help greatly appreciated, Kind Regards, James ----- GIS Undergraduate -- View this message in context: http://postgis.17.n6.nabble.com/Geom-Rast-Intersection-St9bad-alloc-tp4912994p4913835.html Sent from the PostGIS - User mailing list archive at Nabble.com. _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
