Dear Sir I need to create a lattitude grid from the DEM. I have gone through the threads and followed the steps. When I type the statement $$YMAP in SOMA window after setting the extent, working directory and cell size by the spatial analyst > options, i get an error message that "Syntax error at locations 0 of expressions $$YMAP". I even changed the expression as E:\Ph.D\Data_dump\DEM = $$YMAP. How to access these built in functions? Kindly help me sir. With Thanks
