Color Landform Atlas of the United States, Version 2Entry ID: landform_atlas_JHUAPL
Abstract: The Color Landform Atlas of the United States, Version 2 may be
accessed on the World Wide Web at:
The following information was abstracted from:
Please visit this page for additional information.
Currently the following maps are available for each state (except
Alaska and Hawaii, they are coming sometime):
A topographic map optimized to show the
landforms. The same color shading is used
across the country.
A map showing counties in a state. The
background topography has been somewhat
suppressed to allow the county boundaries to
Satellite images of the state. These have been
obtained here directly from the NOAA weather
satellites and use the AVHRR image data.
An 1895 map of each state. These are from an old
Rand McNally Atlas of the World. Not yet all
available, still scanning
A PostScript map of counties in the state.
These are intended for download and printing on a
The first two maps all have the same maximum image length (900 pixels)
so the actually scale varies from state to state. Long narrow states
also have more detailed subsections available. More maps will be added
The elevation key is intended for the topographic maps. The county
maps use the same colors but with less contrast. It may be convenient
to start another browser window and view the elevation key image at
the same time as the map of interest.
The same data and coloring is used for the state maps as for the
previous JHU/APL Digital Relief Map of the U.S. which covers the
U.S. at a uniform scale in 60 GIF images.
Even though the same color scheme is used as for earlier maps a new
coloring algorithm is in use. The coloring for some maps is improved,
for others it is not as good. The old coloring algorithm used a median
cut technique which did not handle small areas of elevation extremes
well. An example problem area is Mt. Washington in New Hampshire, it
was miscolored on the previous maps. The new algorithm does a better
overall job but has occasional problems along the coast.

Use Constraints Using these maps for your project
If you would like to use one or more of these maps for a project
contact Ray Sterner at email@example.com. There are no charges
involved and permission will likely be granted. I do answer my mail
(not junk mail) if it gets through (sometimes it doesn't). Make sure
you include enough information so I can determine if the use is
suitable (address of web sites, or some description of nature of the
application). Applications that would reflect back on the lab in a
negative way are not allowed.
