8 Reasons to Use Rockd

Prior to Rockd, answering the question “What kind of rock am I standing on?” was a complicated process that might have involved searching for USGS or local survey maps, downloading PDFs, and attempting to reconcile your location on them. Using <a href="https://macrostrat.org/map" rel="noopener ugc nofollow" target="_blank">Macrostrat’s geologic map database</a>, Rockd is able to synthesize the underlying data of over 140 (and counting!) geologic maps from all over the world to provide you with a high level summary of your location that includes the age, rock type, and stratigraphic name (if available) of your current location. Additionally, Rockd draws on data from other databases to provide you information about sedimentary basins and physiographic divisions, as well as extremely high resolution elevation data derived from <a href="http://www2.jpl.nasa.gov/srtm/" rel="noopener ugc nofollow" target="_blank">SRTM</a>, <a href="http://topotools.cr.usgs.gov/gmted_viewer/" rel="noopener ugc nofollow" target="_blank">GMTED</a>, <a href="https://nationalmap.gov/elevation.html" rel="noopener ugc nofollow" target="_blank">NED</a>, and <a href="https://www.ngdc.noaa.gov/mgg/global/" rel="noopener ugc nofollow" target="_blank">ETOPO1</a> digital elevation models served up by <a href="https://mapzen.com/" rel="noopener ugc nofollow" target="_blank">Mapzen</a>. This provides you with a much higher resolution vertical accuracy than that provided by the GPS in your phone alone. <a href="https://medium.com/@RockdApp/8-reasons-to-use-rockd-2fa7668fbb25">Read More</a>
