The Development Based On The Pipe Network Management Of Coal Gas Information System

This text is with a view to solve the practical problems that the pipe network of coal gas exist in the production management. If we apply GIS to the pipe network management of coal gas, we will realize the scientific process of the pipe network of coal gas, manage systematically, improve working efficiency and service level, reduce the cost of the management.The text proceeds with secondary development of geographical information system. It regards VB visual programming language as the developing instrument. And it makes systematic theory summary and discussion to based on VB MAPGIS secondary development. On the basis of theory discussion, uses package development and API function development approach, combines coal gas pipe network administrative system make network analysis realize VB procedure. The system realizes all the basis function of geographical information, and it merges MIS function.Then it forms the management system of the best function. Finally it makes summary for the MAPGIS pipe network management system.
