I made a very cool series of maps today, from 2008 to 1991. Well…making them in the loosest sense of the word. The GIS was already done and I just found the building that I needed (a mosque) for a couple of different years and then selected the layers that I wanted. The only tricky part came when I tried to print and save. They would not. So I ended up Print Screening and then Cut and Pasting from there.
