THE STATUS OF TOPOGRAPHIC MAPPING IN THE WORLD A UNGGIM–ISPRS PROJECT 2012–2015
Topographic mapping, Global status of mapping
2016/11/8
In December 2011, UNGGIM initiated a cooperative project with ISPRS to resume the former UN Secretariat studies on the status of topographic mapping in the world, conducted between 1968 and 1986. Afte...
TOPOGRAPHIC MAPPING OF PLUTO AND CHARON USING NEW HORIZONS DATA
Pluto Charon Topographic Mapping Spatial Databases
2016/11/8
New Horizons 2015 flyby of the Pluto system has resulted in high-resolution topographic maps of Pluto and Charon, the most distant objects so mapped. DEM’s over ~30% of each object were produced at 10...
