Topographic Analysis using the National Elevation Dataset

On this site you will find objective topographical research obtained from the analysis of digital data provided by the National Elevation Dataset. Analysis of Summit Steepness for various US states makes up the bulk of the content. Recently added sections include Canadian Summits, USGS Quadrangle analysis.

While of academic interest, this information will also be of use for hikers and climbers looking for overlooked, potentially challenging peaks to climb, or areas with rugged terrain to visit.
