Real-Time Interactive Multi-Resolution Watershed Model


Article Preview

Through the researches and discussions of each constituents of multi-resolution watershed model, the article comes to the conclusion that could apply the LOD(Level of Detail, LOD) technique , the blanking technique and so on to the deletions and replaces of DEM(Digital Elevation Model, DEM) data nodes and the unimportant watershed region in the multi-resolution watershed model, the remote sensing images, the multi-resolution building model, the multi-resolution flood routing model. The method could reduce the data quantity of valley model. The experiment has proved that the multi-resolution watershed model with the applications of this method could not only express three dimensional virtual large scene of the watershed better, but also make the visualization of the mass data model in real-time interactive manner in condition of the computer capability nowadays. This achievement has provided the new thought for the compression of remote sensing images and data transmission of WebGIS in real-time interactive manner.
