摘要
新一代全球数字高程模型ASTER GDEM由22600个1°×1°的分区数据组成,它包含了覆盖全球北纬83°至南纬83°之间的陆地部分,高程精度为±20 m,平面精度为±30 m。本文详细地分析了ASTER GDEM的数据精度,介绍了该数据在石油勘探中的应用。
ASTER GDEM,the newest global DEM,consists of 22,600 1°-by-1° tiles covering land surfaces between 83°N and 83°S latitude.The elevation accuracy is 20 meters and the horizontal positioning accuracy is 30 meters（both at 95% confidence level）.The paper analyzed the data accuracy of ASTER GDEM,and then introduced its application in oil prospecting.
