| Abstract： Public Google Earth satellite images can provide a large number of quantitative information data of geology. On the basis of outcrop information anatomy, precise positioning by GPS and the high resolution satellite image, a new method by integrating outcrop data and Google Earth images for identifying and acquiring geological information was proposed. To test the method of validation, the Ordovician paleokarst outcrop developed in Xekar area, Tarim Basin, was adopted to build karst geological model. The responsive characteristics of several types of geological information, which contains corrosion channels, paleocaves on Google Earth images in Xekar, can be confirmed. A quantitative paleokarst geological database is established. The basic type of data contains the edges of corrosion depressions, the edge of corrosion channels, and the size of paleocaves. Paleokarst geological models, outcrop phenomenon and satellite images are all available data that can be used to analyze the controlling factors of paleokarst in the research area. |
