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...
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...
Small satellites are powerful tools to support many Earth observation tasks. Nowadays, the advances in various fields of technology allow to develop and operate even high resolution optical topograp...
High-resolution satellite images (HRSI) at sub-5m footprint such as IKONOS, IRS-P5 (CartoSat-1) and SPOT-5 HRG/HRS images are becoming increasingly available to the earth observation community and the...
On the one hand, the successful launch of the SPOT 5 satellite in 2002 can be seen as a milestone for DEM extraction and mapping, because its payload includes HRS, a stereoscopic imaging instrument de...
Identifying significant changes to our urban areas is a prerequisite for accurate topographic mapping. This paper presents an approach based on octree data structures to identify change between two se...
High-resolution (submeter) orbital imagers opened possibilities for Mars topographic mapping with unprecedented precision. While the typical sensor model for other Martian orbiters has been the linear...
Cartographic and topographic mapping of the major satellites of the Outer Solar System has been in progress since the late 1980’s, beginning with Voyager image data, and incorporating Galileo and rece...
High-resolution satellite images (HRSI) at sub-5m footprint such as IKONOS, IRS-P5 (CartoSat-1) and SPOT-5 HRG/HRS images are becoming increasingly available to the earth observation community and the...
Digital satellite imagery provides substantial high quality data for mapping, inventorying, monitoring, and surveying. In the last decade, high-resolution satellite imagery from satellites such as IKO...
Data for building topographic database (DLG) and data for mapping are two kinds of data which connected each other, as well as different each other. Though DLG data can be transformed to mapping data ...
The new technology of small satellites (microsatellites) opens a new era in satellite Earth observations. Small satellites such as the ESA’s Project for On-Board Autonomy (PROBA), launched on October ...
The very high nominal ground resolution of OrbView-3 indicates the possible use for mapping up to the map scale 1 : 10000. For OrbView-3 the pixel size projected to the ground is not identical to th...
High resolution mapping systems follow the trend to smaller ground sample distances (GSD) making use of the best technology available at the given time. From the 80 m GSD of ERTS in 1972, the GSD no...
We describe USGS topomapping of Mars at resolutions from 100 m to 30 祄 with data from the latest spacecraft missions. Analysis of NASA 2001 Mars Odyssey Thermal Emission Imaging System (THEMIS) data ...
