Abstract: Deficiency and limitations of wireless network and mobile terminals, and the particularity of GIS data blocks the development in mobile GIS. Aiming at this problem, this paper presents a progressive query method for a mobile GIS service and the corresponding data structure. Experimental results prove that this method can cut down the processing time and increase the data transfer efficiency.
