Elk is a set of tools to generate map and topographical surfaces using open source data from OpenStreetMap.org and USGS. OpenStretMap.org is an open/crowd sourced website of mapping data. It allows you to export XML formatted data of a selected area and then Elk will organize and construct collections of point and tag data so that you can begin creating curves and other Rhino/Grasshopper geometry. USGS is a science organization that provides access to a large range of scientific data pertaining to the earth. Elk uses data that originates from the Shuttle Radar Topography Mission (SRTM) of 2000. This was a shuttle mission where most of the earth was scanned for elevation and packaged in 1°x1° tiles.
