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.

  • Does the rectangle align with the grid (eg not rotated)? You can convert the corners and read that part of the file, but for a rotated rectangle you somehow also need to rasterize the area of interest somehow. – Rutger Kassies Dec 21 '22 at 07:27

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.
