Hi,
I'm beginner in development using GDAL. So I'd like some advises and
tips, let me explain what I need to do.
I need to load a DTED file level 2 and given the parameters
latitude,longitude and width I must create a region (rectangle) and
find the highest elevation in the grid points inside this rectangle. I
need it to be fast, I don't know exaclty how slow GDAL is, so I need
to understand which strategies to useds to increase de speed of this
routine.
I didn't find source code examples of DTED loading with GDAL, So there
are lot's of doubts I have, such as how GDAL stores the DTED since it
was loaded (in an image file?), how to represent this grid area (a polygonon area with elevation points), how to get the elevation of a point
given (lat, lon).
I'd be glad to receive examples, references and tips about it.
Thanks
Ricardo
