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.).
