| Abstract: | On the basis of the existing hydrogeological data in the study area,extraction and recognition of information on natural outcropping points of the karst groundwater system based on ASTER data are carried out.According to the research target and taking the ASTER data as information source and investigation tools,the corresponding image processing and analysis process are formulated,and the related video features of the information on the natural outcropping points of the karst groundwater system are enhanced.With the ASTER data thermal infrared bands for information source,thermal infrared remote sensing theory and technology are applied,and the difference in temperature between the outcropping points of the natural karstic groundwater system and the features of other objects is taken into account.The separability between them is also explored.Combined with the ASTER data of near infrared and visible/shortwave infrared bands,information on the natural outcropping points of the karstic groundwater system is identified. |
