I have 16 DTED maps of (1 degree x 1 degree). I have to generate combined height matrix of maximum 4 (1 degree x 1 degree) DTED maps in my C++ application.
Can someone suggest to me which open source GIS API I should use in Windows 7?
Thanks in advance.
thanks for your valuable reply, i will try GDAL. I have to analyse radio line of sight for two points for communication, that may lie on two different DTED1 map , but the distance between two points will be maximum 150 to 200 km.
and one thing more, i will get two points from another application, and i have to send all height information matrix (rows * column) of that area, that area may be on same or two different DTED 1 maps.
I am confused about DTED 1 map, Whether it is raster file or vector file, How GDAL process it, as a raster or as a vector.
