Geographic Information System (Geographical Information System, GIS) is a management analysis of new technologies developed rapidly in the 1960s, is the product of computer science, geography, surveying, cartography, management of a variety of interdisciplinary core computer science, the basic technology is the database, map visualization and path analysis, processing geographic data input, output, management, query, analysis and decision support computer system. GIS spatial database, spatial database and combine traditional relational database, it has the decision-making, management, analysis, and the ability to output to a variety of spatial information, which is the difference between GIS and other management information systems (MIS). This paper first describes the theoretical basis of detailed definition of the concept of GIS and development status at home and abroad, on the hardware and software of the system components, and application development field, and GIS and has been widely used MIS were compared. This article briefly describes the GIS platform for developers and software products on the market today, several mainstream, and highlights several series of MapInfo's GIS software system development requires technical background for the system development. Geospatial information management needs of the communications cable system access to managed objects, GIS introduced to the campus network cable management to the fiber optic cable to enhance the network management level. Status and the actual needs of the campus network and cable management, the overall system architecture analysis. Integrate various types of data, select the data required attribute information, data model design GIS layers. And cable management features into the design of functional modules. Followed by secondary development module system with MapBasic requirements analysis and design notes. Structure and process design of these modules, described the structure of their data. Finally, the system prototype implementation and the main function of the show. Many functional modules involved in the system design to the the topology path selection algorithm, path analysis is the core function of the GIS This article detailed description of the requirements of the system related to the path network analysis and design algorithm to solve programs - Improved algorithm based on the breadth-first algorithm: the characteristics of the GIS platform, so the path analysis carried out on the basis of queries based on database tables, and an alternative to traditional memory-based data query.
