Hi guys I tried to extract the elavation value of a particular location on the SRTM data i loaded on my database using the following command SELECT ST_Value(rast,ST_Point(-106.2,38.6)) AS Elevation From srtm;
but it only brought out a long elevation column with no value shown. What could be the issue? Also If i try to issue a command like this : SELECT ST_Value(rast) AS Elevation From srtm Where rid = 1304; Error message. "function st_value(raster) does not exist" Cheers! -- Iyke Maduako Masters in Geospatial Technologies Institute for Geoinformatics,IfGI University of Muenster Germany Phone: +4915129048460 Alternative Email:[email protected]
