Abstract

During the Ninth Five-Year Plan period, the Ministry of Geology and Mineral Resources deployed a pilot project for the construction of space database of 1:20 million. Since 2000, China Geological Survey has developed computer mapping systems in combination with regional geological survey. From 1999 to 2006, the China Geological Survey (CGS) completed a number of 1:250000 Regional geological maps using 3S technology in the area of 152,000 km2 in Qinghai-Tibet Plateau and its adjacent areas, in accordance with the unified mapping technical standards. This is an epoch-making project, marking the full completion of the medium-scale regional geological survey of China’s land. What Lu Xun has said, “There is no home-made precise geological map in its territory and its city of a non-civilized country” has been fully realized.

Highlights

  • Computer-aided mapping changes the traditional geological mapping method, speeds up the mapping speed, reduces the labor intensity, and improves the quality of information transmission function and loading function of geological mapping, and gives geologists sufficient time for comprehensive analysis and thinking and improves the understanding of regional geological development and tectonic evolution

  • The projects have had an impact on the basic geological mapping of stratotypic sections and are significant at home and abroad

  • The map represents a new level of expertise achieved by Chinese geologists
