>I am looking for some digital topological data...
definitions:
TOPOLOGY: The branch of mathematics dealing with the non-metric properties
of sets (in contrast to geometry).
TOPOGRAPHY: The branch of geography dealing with the physical
characteristics of a place or region (typically, the terrain).
The contour maps you can buy from the USGS are not topological maps,
but TOPOGRAPHIC maps.
