Mapping means a lot of different things to a lot of different people. You ask The Word Shop, and they just want a navigable map with a single point indiciation their location. You ask Development Seed the same question, and you get a completely different answer. You ask my wife, who is a GIS analyst exceedingly proficient in ArcGIS, and you'll get an entirely different concept of the word "map".

That's what makes this hard.
