APPLICABILITY OF FIRST PULSE DERIVED DIGITAL TERRAIN MODELS FOR BOREAL FOREST STUDIES
DTM quality first pulse last pulse laser scanning TIN grid
2015/8/13
Detailed high-resolution digital terrain models (DTM) can be obtained using airborne laser scanner data. This paper evaluates the
accuracy of DTM derived from first return of laser scanner data for f...
INTEGRATION OF TERRAIN MODELS AND BUILT-UP STRUCTURES USING CADTYPE EULER OPERATORS
Triangular Irregular Network (TIN) models, Euler Operators
2015/3/9
Until recently terrain models were developed in a GIS, and built-up structures were modelled using a CAD system. Extending the
current “2.5D” TIN model by incorporating CAD functions is a necessary ...
Optimisation of LiDAR derived terrain models for river flow modelling
Optimisation LiDAR terrain models river flow modelling
2009/9/11
Airborne LiDAR (Light Detection And Ranging) combines cost efficiency, high degree of automation, high point density of typically 1–10 points per m2 and height accuracy of better than ±15 cm. For all ...
Photo-Textured Digital Terrain Models as a Basis for Regional and Local Planning
Regional Planning DTM Ortho-rectification
2015/3/9
Many cities in the second and third world experience currently strong urbanization and are expanding fast. These
development dynamics are so strong, that the traditional maps as a basis for planning...
VISUALIZING TERRAIN MODELS FROM CONTOURS – PLAUSIBLE RIDGE, VALLEY AND SLOPE ESTIMATION
Terrain Modelling Contours Interpolation
2015/3/9
Applications such as modelling and animation of water runoff are becoming more and more important, and demand better surface
orientation information than is available from traditional interpolation ...
