On this page I am assembling a collection of mapping and terrain modeling tools.
This is an ongoing effort and I'm just getting started so come back later if it
isn't developed enough for you now.

The Thematic Level selects a geography level for drawing thematic statistical maps.

1991 Metro. Stat. Areas
1992 Congressional Dists.
cities, towns, and CDP's
Minor Civil Divisions-New England only
Census Tracts: 15-20 city blocks
Census Block Groups: 4-5 city blocks
Thematic variable selects a statistical variable to use in thematic maps.
(must be used with tlevel and tmeth above)
Family Size: persons per family
Household Size: persons per household
Population Density: persons per sq mi
Median Family Income
% of Population Age 0-4
% of Population Age 5-9
% of Population Age 10-19
% of Population Age 20-49
% of Population Age 50-64
% of Population Age 65 and over
% of Population White
% of Population African-American
% of Population American Indian
% of Population Asian
% of Population Hispanic
% of Population from other ethnic groups
% of Households Owner-Occupied
% of Households Renter-Occupied
Thematic method selects the classification method to use in thematic maps
(must be used with tlevel and tvar above)
" q" = Quintiles
" i" = Equal Interval
These classes are calculated over the entire country, not just the map area. Quintiles (5 classes of equal size) tend to provide better contrast between values around the average, while Equal Interval (5 classes with an even range of values) tends to emphasize the extremes.

I made an imagemap index of the USGS 7.5' DEM archive so that the DEMs can be
found by map location instead of only by name. The imagemaps are also linked to
listings of DEMs by coordinate order just in case you wish to yse a text only
interface (silly in this case).
Other DEM Data Sets from
USGS via FTP
There are other scale DEMs as well as the 7.5' ones and pointers to where they
may be found together with brief specifications can be found on my
DEM Data Sets & Information page.
The USGS EROS Data Center's GTOPO30 is a global digital elevation model (DEM)
with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer).
Here is an image map

The MapBlast server has the best interface for use with the Newton. Very good maps too.
With a somewhat cluttered front end, MapQuest is OK. The maps are almost as good as MapBlast's too.
Another clean one is Yahoo Maps, which has a very simple front end. Maps are OK.
Database Query & Map Generation: Online Resources and Examples page is a really good collection of pointers to mapping and web resources.
