Users also can “snap a line” to gather elevation profiles between two points on a map. The new data builds on an existing 2009 LiDAR database that wasn’t as precise, Sip said in an interview.

Most elevation maps are created by the USGS using low flying aircraft that take photos of the land below which is then translated into topographic maps.
