Preparing The Updating of The Belgian Topographical Database: A Challenging Project
Photogrammetry Updating Three-dimensional
2015/7/8
There is more to preparing the updating of a topographical database than the conception of an appropriate data model. We needed to
thoroughly study the available internal and external data sets. Furt...

Representing Uncertainty in Visualisations of Future Landscapes
GIS visualization understanding
2015/7/7
The use of computer-based visualisations to depict landscape futures is increasingly common in environmental decision-making,
particularly where information must be communicated to a wide and non-exp...
The reconstruction of 3D city models has matured to the point where large data sets are now available. As most of the data collection
methods used are based on airborne sensors like e.g. aerial laser...
Generalization of Dense Digital Terrain Models While Enhancing Important Objects
Cartography DEM/DTM High resolution
2015/7/7
Laser altimetry is a leading technology for the extraction of information of physical surfaces, and hence it is the main source for
generating a dense digital surface of the terrain. This results in ...
The paper presents a low-cost navigation system, which is based on digital terrestrial images. The database of the test area is filled by
digital images about road junctions, crossings, and other 刬rr...
Experiences in Upgrading of Large Databases of Satellite Images
