Hello, How do you plot a simple ascii grid of values spatially? I have a .dat file that contains 180 rows and 360 columns corresponding to a range of 90 to -90 (180:rows:latitude) and 0 to 360 (360:columns:longitude). I believe that the position of the cell at Column 1, Row 1 corresponds to a cell of position 90n, 89n, 180w, 179w but cannot be sure until it is mapped. So, I need each cell value to correspond to a 1x1 deg lat/lon cell size when plotting. Is there a way to do this easily? Thanks, ~Matt
