Pyramid Management and Real-time Visualization of Massive 3-Dimensional Terrain Data
Visualization Level of Detail Computer Vision Simulation Geography
2015/12/3
3-Dimensional terrain visualization has been widely used in the fields, such as games, geographic information system (GIS), remote sensing (RS) and virtual reality (VR). Rendering large scale 3D terra...
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 ...
This paper presents a research and development project that will provide an extension to 2D geo-databases for handling large terrain
data. It first discusses application requirements and system desig...
A GLOBAL “NATURAL” GRID MODELING METHOD BASED ON TERRAIN TOPOLOGICAL STRUCTURE
Natural GNG Topological Structure Morse Theory Representation
2014/4/21
In this paper, a Global “Natural” Grid (GNG) modeling method based on the terrain topological structure is proposed. GNG
partitions the earth surface into “natural” cells by using the natural terrain...
