Hi,<br><br>I'm using Gdal to load dted files and get max elevations of a region, but I have constraints concerning speed. Inspite of loading geotifs generated from dted has reduced a lot the processing time, its still not enough to the constraints I have. I'm loading geotiffs which represents dted L1 files, reading its points using rasterIO and verifying the max elevation of a rectangle area given ( lat, lon, width).<br>I've noticed the more expensive is the data reading, so I'm thinking about storing the dted (or geotiff) files in a Postgis. Would it increase the search speed?<br>Does anyone know the best way to store dted files in a Postgis? I thought about storing geotiffs (generated from deted using gdal), but I dont now exactly how it would work. I know there are spatial queries in Postgis and I think it would be very useful in my case.<br><br>I look forwarding to receving any tip of how to do this.<br><br>Thanks in Advance,<br><br>Ricardo Rodrigues<br>Brazil<br> </body>
