Digital globe is a visual system based on geographical coordinate, provided with multi-resolution, mass data and multi-dimensional display. Three-dimensional terrain visualization is an important composition of researches about terrain visualization technology and digital globe, also is the foundation of realizing the multi-angle, multi-layer, real-time generation, display analysis and roam of three-dimensional...
To meet the requirement of real-time vehicle navigation, a new path planning algorithm based on partitioned urban transportation network is proposed in this paper. The foundation of the algorithm is that an actual road network has its particular spatial distribution features, and GIS has strong visual editing functions for transportation network. According to the size of the transportation network,...
For addressing the problem the society has higher and higher demands of government constitution and management of mid-and-long term macro-planning. The five-year planning MIS research on medium-small city based on GIS are established based on Visual Basic6.0 and components of GIS software-MapX, making the management of general planning realize digitization, data indicator become standardization, results...
In order to improve and strengthen the ability of survey data processing, MATLAB software is introduced in the course of Error Theory and Survey Adjustment as the teaching assistance method. Based on its ability formidable calculating function, graph handling ability and the rich toolbox, the MATLAB-based Error Theory and Survey Adjustment experiment has been set up. It improves the students' creative...
