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
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
Where rid = 1304;
Error message. "function st_value(raster) does not exist"
