I wish to utilize cartosat DEM, publicly available form bhuvan site. However, I have analyzed and seen that the elevation values from cartosat DEM are very similar to ellipsoidal height of GLAS/ICEsat altimetry data. Before I use the DEM data, I wish to know whether the elevation values show actual orthometric height or ellipsoidal height?
