The electric notebook is often used for field surveying in survey departments. But it only records position coordinates, and cannot display any map surveyed. Now a digital surveying and mapping system of pocked PC can be used for this purpose. This paper discusses the selection of development tools, the general structure, function of the surveying and mapping system. According to the design fundamental of graphical interfaces, a large scale software system of pocket PC is designed with data calculation, collection and management. It can record the primary data, map and attribution of the surveyed object, and can conveniently note text or content. More important, it can look over the actual landform and directly draw maps by the surveyed data without continuing to edit and draw indoors. At the same time, the paper introduces some problem of its realization in development. With the development of pocked PC hardware, a digital surveying and mapping system of pocked PC will be widely used in the map and data updating.
