Im trying to create a matrix of elevations of some area.
To be more specific, i want to create a 21x21 matrix with 1 km gap between the matrix cells. I have the lat and long of the center of the map\matrix.
for example, if i type "load korea" on the MATLAB command then i get, among the rest, a variable with the name "map" - a 180x240 matrix that contains elevation values for each point.
How can i get a map like this for every area i want?
thanks a lot,
