All Implemented Interfaces:

ElevationProvider

public class SRTMProvider
extends AbstractSRTMElevationProvider

Elevation data from NASA (SRTM).

Important information about SRTM: the coordinates of the lower-left corner of tile N40W118 are 40 degrees north latitude and 118 degrees west longitude. To be more exact, these coordinates refer to the geometric center of the lower left sample, which in the case of SRTM3 data will be about 90 meters in extent.
