Application of GIS technique to natural gas pipeline management

The GIS (geographic information system) technique is a newly developed data management technique. It is the combination of geography, computer science, cartography, information science and real and remote control techniques. The GIS technique has been applied to many domains since it came out, and as the technique grows its applied fields is widen, e.g. land management, city information, transportation, fire protection, city water supply, pubic security, travel information etc. This paper introduces the GIS technique to natural gas pipeline management. Natural gas pipeline is a city´s lifeline, as the city enlarges, the natural gas pipeline becomes more and more complicated. How to keep the lifeline run in the course of nature, a good management method is very important. The GIS technique takes natural gas pipeline management to a new level. With an elaborately designed city natural gas pipeline information management system, the natural gas department can make an optimal decision for planning, construction, maintenance and emergency responses etc
