A GIS project visualizes the fascinating triangulation network created for the historic Hayden survey of Colorado. One of the great surveyors in the American West is undoubtedly Ferdinand Vandeveer Hayden. A physician during the Civil war, he rose to be chief medical...

Essentially the elevation is taken from an underlying terrain or digital surface map as points, which...
