Scope:elevation:readElevation, altitude, and other "z" measurements from different sources (ex. GPS, digital elevation models) can be measured with different vertical datum (reference point), resulting in incompatible measurements. UAS regulation uses "Above Ground Level" for drone heights, which requires establishing ground level. This data service converts elevation and altitude measurements between common vertical datum: ellipsoidal (WGS84/common GPS), orthometric (US only - NAVD88/measurement above geoid), and Above Ground Level (AGL). Above Ground Level (AGL) is calculated based on the difference between input z value and surface elevation in compatible datum.
NOTE: This service is only available in the contiguous United Sates.
NOTE: This service is limited to 3600 requests per hour.
Returns a GeoJSON feature collection with requested transformations (see below) between WGS84, NAVD88, Above Ground Level, or surface only.
