EA DEMs Data Precision

Thursday, September 3, 2015

UPDATE: An illuminating and quite hilarious read over here. The release of the LiDAR sourced EA DEMs is garnering some nice attention around the world although Martin spotted that the elevation values are recorded to a precision of attometers. Yes that’s 15 to 17 digits after the decimal point!! As Martin points out, this is a huge waste of bandwidth and, I imagine, a default export setting. As I noted yesterday, the interface is functional, if a little clunky, and could do with some improvement.
