Applying two dimensional Kalman Filtering for Digital Terrain Modelling
Applying two dimensional Kalman Filtering Digital Terrain Modelling
2016/5/23
Digital Elevation Models (DEMs) have been increasingly used to model the terrain surfaces to provide the 'physical bases' for environmental studies. However, DEM is subject to systematic errors, rando...
DERIVING LAND USE AND CANOPY COVER FACTOR FROM REMOTE SENSING AND FIELD DATA IN INACCESSIBLE MOUNTAINOUS TERRAIN FOR USE IN SOIL EROSION MODELLING
Illumination variations correction of topography induced constrains Canopy cover factor estimation NDVI

Soil erosion is one of the severe land degradation problems in many parts of the world. It not only affects on decreasing agricultural productivity but also it causes disasters such as siltation of re...
Procedures and Software for High Quality TIN Based Terrain Surface Reconstruction
Acquisition Modelling Reconstruction Algorithms Automation DEM/DTM Software
2015/12/16
Algorithms and software for correct reconstruction of the terrain surface by using data acquired by digitization of existing maps have been developed. The software enables efficient high quality forma...
Multi-image Shape-from-shading: Derivation of Planetary Digital Terrain Models Using Clementine Images
High-resolution DTM extraterrestrial surfaces reconstruction method
2015/7/8
In many cases, the derivation of high-resolution digital terrain models (DTMs) from planetary surfaces using only conventional
digital image matching is a problem. The matching methods need at least ...
Determination of Terrain Models by Digital Image Matching Methods
DEM/DTM Matching Hierarchical
2015/7/7
Today, digital terrain models (DTMs) are used in many fields of science and practice. When modelling the earth’s surface it is
necessary to make a clear distinction between terrain models, i.e. model...
