Use the zoom option on the info tab to get a more precise view of the surrounding area. It will give you your precise location as well as where the borders to certain geographical features are. Using the map I will often see dots moving, but their lines will be quite far away form them... can't tell if the dot is in the wrong location or if their movement line is... basically, I just take what I see on the map at face value, ten use the zoom feature to actually know where I am. Also helps when you've got a large dot-sized army and want to know if just clipping the forest will actually slow you or not.
