In oil and gas field surface engineering survey, quick data collection, processing, output and analysis are indispensable to satisfy the needs of selecting survey methods. Work efficiency and survey achievement quality can be greatly improved through application of Global Mapper as basis platform. Through concrete analysis on input and output data, combined is Global Mapper with other relative software so as to realize the following functions: extraction of contour lines, comparison and selection of 3d visualization schemes of pipeline routes, extraction of vertical section of pipeline routes, data format conversion between CAD and Global Mapper, processing of data from Handheld GPS receivers and correction and stitching of images. Study results show that application of Global Mapper in oil and gas field surface engineering survey can solve technological difficulties in an even better fashion, realize automation in some processes, reduce the human cost and improve the working efficiency.
