Generally, remote sensing technique serves as an effective method to recognize information about karst topography, rocky desertification and karst collapse. Interpretation of remote sensing images, in combination with field verification and cartographic generalization, provides basic data for updating the program database and compiling synthetic maps. In interpreting remote sensing images, automatic extraction can make it more efficient and visual interpretation can improve its accuracy.展开更多

This paper summarized the research trend of geoscientific mapping in China and Southeast Asia and introduced the significance, contents, technical routes, operating methods and progress of the project. Through bilateral and multilateral cooperation, this project builded an international cooperation platform for mapping and completes the preliminary compilation of related karst geological maps in China and Southeast Asia, thus filling up the blank of karst geological maps in this region.展开更多
