- Hi Jacob,
What you need to do with your map to make it useful is to georeference
it. This link from the Harvard Graduate School of Design presents a
method of doing this to old maps using ArcGIS and Google Earth.
http://www.gsd.harvard.edu/gis/manual/georeferencing/index.htm
The presentation is a little hard to follow since it is in something
like flash, but if you are interested in a version of it that I broke
up and placed in a MS Word Document contact me off list and I will
give you a copy.
Take Care,
