Hi Dan, thank you very much for your hint and sorry for my late response. First of all, "Raster to Point" works fine. Unfortunately though, the points do not have lat/lon coordinates that can be exported. So I tried the "Convert Coordinate Notation", which is way too timeconsuming for large amount of points (4 million points took 8 hours). The weird thing is, when selecting a point, I can see the exact coordinates on the bottom of the pop-up window (see screenshot below). However, I can't access/export this information as it seems. And since it seems to be available, it shouldn't take that long to store the lat/lon information in an array I can access (at least that's my assumption). I need the export to further process image data in Matlab. Ideal would be a matrix of: pointid,grid_code(actuall data),latitiude,longitude Do you have a suggestion how to faster get the lat/lon information of every point ready for export? Cheers Marius
