I'm working on a project that needs a 'database' of terrain altitude data. For a given landmass, we need to identify the highest point in each square of a grid, where each square has sides of one nautical mile. We also need to be able to identify a number of obscuration points (eg TV transmission masts or tall buildings). Can anyone point me in the right direction ? Many thanks in anticipation.
