Elevation Data

These data are for use in the Climate Impact Reports tool. Currently the service endpoints query ASTER GDEM elevation data for Alaska and Western Canada. Each query fetches three values: minimum, maximum, and mean elevations derived from corresponding interpolations used to resample the source data from 30 m spatial resolution to 1 km. This technique is used to assure elevation fidelity between the original and downsampled data.

Service Endpoints

  • Point Query: Fetch values for a single geographic point.
  • Polygon Query: Fetch zonal statistic values for a single polygon (HUC, protected area, fire management unit, etc.).
