Recently, geographical information system (GIS) is the combination of savior and operation and information regarding distribution of geographical space. Applied to more and more wide fields of industry, GIS has developed a school of one´s own with its mixed structure of data and the unique annalistic of geographical space, making it start to be employed into tax system. All the above can be approved by improving efficiency of management as well as increasing capability of management. Through annalistic GIS technique of subassembly and comparison to WebGIS and VC++, we decide to adopt VC++ based on geographical information system of enterprise distribution that was projected for second times. By dint of computer, the system complete the electrical map of enterprise distribution which be utilized only after the first registration. It realizes such features as eye of hawk zoom out and zoom in of a city’s map, roam, arrowhead, marks of serial number, dot option, column option, round option, optical symbol, drawing control, giving number according enterprises, seeking a name of enterprise, adding to and delete enterprise, etc. certainly the latter several features only be eligible to the administrators. When choose the optical type and select from them, the selected name of enterprise would be visible, and then click the name of enterprise. As result of this, the name of enterprise will be amplifier and show in the center of a map, flickering continuously, show the detailed information of a company. Owing to the limit of time and condition, I am afraid that the unfinished features that I should have planned to complete in a form of C/S need to realize in the later extending.
