Using ArcGIS 10 I want to create a fishnet with its bottom left coordinate = (-450000,-1401771.01064457)
I then want 71 rows above from this point and 79 columns right.
Based on 36000m by 36000m cells.
I am not sure if the one coordinate i have is the origin or the y a-axis coordinate.
How do I find the other coordinate so I can create the fishnet?
