This is a map I did for a lecturer in Manchester Business School:
Fortunately I did not have to draw all this. I used ESRI Data & Maps instead, a data product that comes with ArcGIS, and assembled the content and general layout in ArcGIS.
However, in spite of all of ArcGIS’s capabilities, it is no good for advanced graphics design, so I put it into CorelDraw, which simply is a matter of copy-paste. Then I rearranged a few elements and added a some outlines – finished!
Well, it sounds easy, but there is a lot of trial and error involved, so all in all it took me about a day.
