ElevationProvider

public class SRTMGL1Provider
extends AbstractSRTMElevationProvider

SRTMGL1 contains elevation data for most of the world with 1 arc second (~30m) accuracy. We use the mirror of OpenTopography, as the official SRTMGL1 download requires authentication. http://opentopo.sdsc.edu/raster?opentopoID=OTSRTM.082015.4326.1

TODO: In addition, NSF requires oral acknowledgment during all news media interviews. TODO: This is weird, we have to check if really want to use OpenTopography then, see: http://www.opentopography.org/citations

When using this data we have to acknowledge: This material is based on data services provided by the OpenTopography Facility with support from the National Science Foundation under NSF Award Numbers 1226353 & 1225810 National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA), 2013, SRTMGL1: NASA Shuttle Radar Topography Mission Global 1 arc second V003.
