Because of low processing speed of CPU and small memory space, time efficiency of portable hardware, where Mobile GIS is running, is low when processing the mass data. A variety of plans, which can improve the time efficiency of rendering the mass data by application software at user side of Mobile GIS, were studied in terms of development language selection, rendering process control, memory mapping, as well as special processing of different data formats. These technical plans were practiced in case studies based on the system platform of Windows Mobile and the development language of C++. Development strategies we got will improve the time efficiency of mass data rendering by Mobile GIS and make it easy to operate for users.
