From Geological Remote Sensing to Land Resources Investigation
从地质遥感迈向国土资源普查

This paper briefly reviewed the significant achievements on geological remote sensing in China in the 20th century, and illustrated four momentous breakthroughs: plate tectonic demonstration and linear style analysis, digital geology and ore prospecting, the discovery of quaternary geology and geomorphology, routes selection and sites selection of engineering geology. The paper indicated the new tasks of land resources investigation in the 21st century. There are urgently needs for intensifying the research on remote sensing information mechanism, information fusion and sharing, interdiscipline, capabilities of socio-economic statistical and spatial analysis, and attention on moon-probing plan and remote sensing mapping.
