GIS technology and application on oil-gas pipeline construction

Long distance oil-gas pipeline construction is complex. GIS technology is applied to this field and provides a high-tech method for construction operation and management. The digital pipeline is the main feature of the 21st Century's oil-gas pipelines. The new oil-gas pipeline construction in China has the aim of high standards, good quality, advanced technology and best efficiency and GIS technology gives a powerful tool to accomplish this target. GIS and remote sensing technologies are used on route selection of the West-East Nature Gas Transportation Cross Continent Pipeline. The remote sensing images and revising maps of 1:50000, based on new SPOT images, produced from a GIS system are offered to the planning department of the pipeline and used for in situ investigation which obtain wonderful results.
