How to query the highest altitude within an area of interest in a DTED?

Question

I have a rectangular area of interest, and each vertex of this rectangle is defined by a pair of coordinates (latitude, longitude).

Parsing a DTED, how could I find the highest altitude within this rectangular region? I'm using the dted library for python, but I'm open to solutions using GDAL as well.

Thanks in advance.

Answer 1

If the AOI layer aligns with your DTED grid, try:

1. clip the DTED grid in your AOI.
2. convert the clipped grid to points
3. query the max value in altitude column.
