Hi there,
I got excel dataset which has longitude(1xn)), latitude(1xn) and elevation(1xn) as described in the attached file.
How can I convert elevation dataset into NxN matrix?
Note: Data points are randomly distributed. not in exact order as described in the example.

Set N to a smaller value, probably not more than about 1500 or so.
