Tong Xiao · Cehui kexue · 2006
The paper is based on analysing systems of global spatial data browse and display,adopts processing mode of global spatial quadtree and viewpoint correlation, then uses multithreading theory in management and display of massive datas, and establishs reasonable mechanism of multithreading accessing, then uses pyramid tile data set to manage images and DEM.It realizes distributed storage and distribution in LAN, and develops experiment system of global massive spatial data management clientside called GlobalView.
