For the 1000 year question, Hedberg Maps worked on this as a project
over 10 years ago, on a very local level, in our Cities at the
Millennium series (http://www.hedbergmaps.com/store/catalog/203). We
used a variety of sources, often state-by-state based. Different things
had altered significantly in different places: significant shoreline
changes i nBoston, NEw York, San Francisco and Miami. altering stream
beds in Kansas City (but not St Louis). Vegetation changes most places.
There was some significant human impact on the 1000-year-old landscape,
especially near present-day St Louis and Phoenix. It was an interesting
project, but it really required cobbling together a lot of disparate
sources.
