Charon New Horizons Global DEM 300m July 2017
On July 14, 2015, NASA's New Horizons spacecraft made its historic flight through the Pluto system. This detailed, high-quality global mosaic of Pluto’s largest moon, Charon, was assembled from nearly all of the highest-resolution images obtained by the Long-Range Reconnaissance Imager (LORRI) and the Multispectral Visible Imaging Camera (MVIC) on New Horizons.
This digital elevation model (DEM) or topography data represents the hemisphere visible to New Horizons during the spacecraft’s closest approach. The topography is derived from digital stereo-image mapping tools that measure the parallax – or the difference in the apparent relative positions – of features on the surface obtained at different viewing angles during the encounter. Scientists use these parallax displacements of high and low terrain to estimate landform heights.
DEM is available in Equirectangular projection at an equatorial pixel scale of 300 meters per pixel. The DEM is also available in 32bit ISIS3 cube format.
This DEM was produced using radii of 606 kilometers for Charon.
