I have multiple geo referenced scanned maps from the 1950's, Like 60 of them.
I need to clip some white space off the edges so I can apply a fishnet.
So the main question is I have a 50k nts grid where the maps sit perfectly within each grid tile, When i try to clip the map to the grid it does nothing because it is reading the outside border of the nts grid. how would i get the clip to read each individual grid tile for a clip?
thanks
Joe,
can you try and format your code to make it readable...
The point about making a mosaic is that you don't have to do all this clipping.
No extra time and no extra disk space.
THIS WORKS!
