ElevationProvider

public class GMTEDProvider
extends AbstractTiffElevationProvider

Elevation data from Global Multi-resolution Terrain Elevation Data 2010 (GMTED2010). The data provides 7.5 arc seconds resolution (~250 m) global elevation data. The data is available between latitudes of 84°N and 70°S. The data is available as .tiff and the we are using the mean elevation per cell (other options are median, min, max, etc.).

More information can be found here: https://topotools.cr.usgs.gov/gmted_viewer/

When using the data we have to acknowledge the source: "Data available from the U.S. Geological Survey.", more information can be found here: https://lta.cr.usgs.gov/citation
