Concept

Provide digital elevation heightmaps to an accuracy of three seconds in a format and with methods so that entry and intermediate level programmers may quickly and easily create new and interesting 3D cartography.

Source and Credits

The data in this repository was sourced from Jonathan de Ferranti's web site: Viewfinder Panoramas.

• Jonathan de Ferranti's 3 second data set
• Supplies about one data point about every 90 meters

And, of course, none of this would be possible without GitHub.
