A friend works with LIDAR data. He needs to write a program with which he extracts (from an vector ASCII x,y,z file) the row containing the maximum z (height) and write a new vector ASCII containing the result.
(He writes in C++) Since he deals with lots of ASCII files he needs to batch this job. How about doing this in GRASS? With R maybe? Thank you, Nikos -- Nikos Alexandris .
