Hopefully this is a question with a quick answer.... <div><br></div><div>I have a few rasters loaded into PostGIS 2.0 alpha5. I loaded them with tiles at 256x256 px (no real reason why I chose those dimensions.) When I run a simple ST_Value() statement, returned is one record for each tile. And, of course, every one of those will be blank except for the tile that contains the location. Is there a way to return only the value, and not a full array of nearly empty cells? (of course, only one value is returned when the raster is not-tiled but I'm not sure if that's the way to go.) Thanks. <div>
