Hi,
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).
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?
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.
I look forwarding to receving any tip of how to do this.
Thanks in Advance,
Ricardo Rodrigues
