Panoramic Aerial Maps of the American West
including the states of Arizona, Colorado, Nevada
New Mexico, Oregon, Utah, Washington, and Wyoming

This collection of panoramic maps was produced for public instruction and
unfunded academic research. The maps were created by combining
numerical elevation data collected by the Shuttle Radar Topography Mission
and linear data acquired from the old United States Geological Survey’s
national atlas. Both data sets have numerous flaws, but I believe that the
resulting maps are worthy of your inspection and use for non-navigational
purposes. Looking down on the land from a high place gives fresh perspectives
and new appreciation for a country’s otherwise unseen geography.
The digital master models from which all the panoramic maps are derived
were created by combining numerous 1-degree, 3 arc-second SRTM digital
elevation models, each containing 14,400 individual elevation points located
at approximately 90 meter horizontal intervals. The master model for the Colorado
Plateau was constructed by combining 144 1-degree SRTM models. It contains
over 200,000,000 elevation points. If laid out on a single piece of paper with
elevation points separated by 1/72 of an inch, the resulting terrain map would
measure more than 16 feet on a side. All views are made from very high
simulated elevations, usually between 25 and 100 kilometers above sea level.
Most encompass areas containing thousands of square miles.
