Based on Windows CE PDA appeared, and then a lot of surveying and mapping workers to be treated as an ideal field data collection tools. According to the advantage of PDA and the commonly used digital mapping mode insufficiency, based on the development of PDA digital mapping system (handheld electronic flat mapping system) has become a new digital mapping technology development direction. This paper studies the PDA based on digital Mapping system should have the basic function and the function in the design and implementation of the key technology, the use of embedded development tools EVC3.0 and AutoCAD secondary development tools Visual LISP programming development the pocket electronic flat Mapping system - Palm Mapping V1.0, realized the PDA control total station for field data collection, recording, graphics and field graphics data to the office work based on PC digital Mapping software MD6.0 standard digital topographic map of the conversion. This system is to improve the field mapping work efficiency, reduce homework personnel especially drawing personnel work burden, make field digital mapping is more convenient quickly.
