Greenness_Service


The TNM Elevation Query Web Service returns the elevation in feet or meters for a specific latitutde/longitude point from the USGS Seamless Elevation datasets hosted at the EROS Data Center. The elevation values returned default to the best-available (highest resolution) data source available at the specified point. Alternately, this service may return the value from a specified data source, or from all data sources. If unable to find data at the requested point, this service returns an extremely large, negative value.
