Create matrix of latitude/longitude Modis.

Hi,

I start using Modis data (LST and albedo data, 1km), and I have problems getting their (correct) lat/lon for each pixel of the grid.

First of all, if you've already use these kind of data, how do you get your grid of lat/lon matching your data.

Otherwise, what would be the best method to create a matrix of lat/lon, knowing the coordinates of the corners (lets say [59 -81;69 -121;70 -88;59 -59]). The datas are matrix of 1200*1200.

What I did was linear interpolation, but that's of corse not correct, because it doesn't take into account the curvature of the earth.

If anyone has some idea while I'm still working on that, I'll take it. Thanks a lot.
