资源简介:
ArcticDEM是一个高分辨率数字表面模型数据库,由NGA-NSF倡议创建,使用光学立体影像、高性能计算和开源摄影测量软件自动生成北极地区的高质量数字高程模型。该数据库包含从2007年至2024年间获取的数十万个立体数字高程模型,数据来源于WorldView系列卫星和GeoEye-1卫星,分辨率为0.32至0.5米。数据以两种形式提供:保留时间分量的条带文件和用于变化检测的镶嵌文件。
ArcticDEM is a high-resolution digital surface model (DSM) database developed under the NGA-NSF initiative, which automatically generates high-quality digital elevation models (DEMs) of the Arctic region using optical stereo imagery, high-performance computing, and open-source photogrammetric software. The database contains hundreds of thousands of stereo digital elevation models acquired between 2007 and 2024 from WorldView-series satellites and the GeoEye-1 satellite, with a spatial resolution ranging from 0.32 to 0.5 meters. The data is provided in two formats: strip files that retain temporal information, and mosaic files intended for change detection.
