As a kind of computer system about spatial data management, spatial information analysis and communication, Geographic Information System is an applied High-Technology which involves geographic science, information science and computer technology. Now, It is widely used in various fields such as ground application, resources management and city & district design. Moreover, It has become a powerful tool resulting in socially sustainable development. The Research and Development of Urban Programming and Management System. Based on the theory of AutoCAD2002, adopting Object ARX technology, this system contain five main modules including terrain, earthwork, roadway, plot and pipeline. Because of possessing both the traditional advantages of AutoCAD and the up-to-data technology of AutoCAD2002, the data-mapping technology of this system is build on the classic design level all over the world. The main functions of this system on road plot contain basic road protrat, including single board and multiple board, etc. Protract series roadway with parameter, dispose infall automatically, correct radius of arc, edit vehicle harbor and trumpet, the green strap of central road. The functions of this system include Edit to mark various road parameter automatically, fast formation the road system analysis diagram, draw the curve form and hand over some form, road to sit to mark form etc. automatically. The automatic manhunt marks each control point to sit the mark and nature also, design elevation, define a number of network, the road elevation in brief and quickly, automatic born and each design depth of horizontal, the vertical section structure and tectonic plate analysis diagram. Vertical include the mark of roadway stake, traverse and endlong, the earthwork of roadway , count and label of level grade. In addition, the applied technology and research direction of GIS are discussed, focusing on the status quo and the application types of GIS. Also, some basic theory and research-hotspots are mentioned in this paper.
