%X Processes-sharing memory address space was created on the base of divided large-scene watershed model(including DEM terrain,terrain image,surface features model,object model image,metadata) by using memory mapping file technolog(MMFT) in the memory.Firstly,this paper discussed the function and its functions that the MMFT would apply.Secondly,analyzed the function and its principles which transferring and storing large-scene watershed model(size is about 4 GB),and analyzed achievement courses detailedly conc...
