Ellipsoidal and Geoidal Elevations

Use the map below to draw a line or polyline and generate an elevation profile displaying both ellipsoidal (WGS84) and geoidal heights. Elevation data is retrieved from Bing Maps Elevation API . The interactive map is powered by OpenLayers, and elevation profiles are visualized using ApexCharts. Geoidal heights are computed based on the Earth Gravitational Model 2008 (EGM2008).
