ASTER-GDEM数据在塔吉克帕米尔成矿带区域化探中的实际应用
Application of Aster-GDEM Data on Regional Geochemical Survey in Tajikistan Pamir Metallogenic Belt
摘要
Abstract
Pamir, in Tajikistan, located in alpine region, relatively lower geological researching level, lacks complete topographies with the scale of 1 to 50 000 and 1 to 100 000. Tajikistan has power protective policies, obtaining large scale topography data is very difficult, so to carry on regional geochemical survey topography data with scale of 1 to 250 000 has become the first key problem. According to the above matter, the project carries on monographic studies. Based on the ASTER-GDEM elevation data, platform of ARCGIS 9. 0, disposing DEM data, we successfully extracted the topography and water system with the accuracy of 25 m. At the same time, the comparison between the extracted data and actual data indicates that the topographic data extracted is reliable and credible, and the accuracy is close to the scale of 1 to 50000. And finally the problem encountered above was solved, a new, quick and effective method for abroad geological survey is provided.关键词
