	You'll need to define where the map itself is coming from, how
coordinates equate to map points, etc.

	The solution will vary significantly from using, say, Google Maps (sign
up for access to the API)

... to ArcGIS which has its own API for Python.

	Are you simply wanting to identify /points/, or draw /regions/ -- I
don't think Google Maps does regions, only points.

	The Plotly package can apparently draw maps -- but you need to
subscribe to some map provider for the actual maps it works with; otherwise
it may just do polygonal data from coordinates.

	Are you scanning USGS topographic maps into image files -- then you
need image manipulation and some way of encoding lat/long into pixels.

This obtains the map vector data from a provider, then generates/saves
image files to use PhotoShop/GIMP for adding overlays -- you might be able
to do that part using the Python Imaging Library (but again, knowing how to
map coordinates into the image is going to be a factor).
