ArcticDEM 32m

ArcticDEM is an NGA-NSF initiative to automatically produce a high-resolution, high-quality digital surface model (DSM) of the Arctic using optical stereo imagery, high-performance computing, and open-source photogrammetry software. OpenTopography is distributing the ArcticDEM mosaics (version 4, released July 2023) assembled from all ArcticDEM strips to provide a consistent and comprehensive product over large areas. ArcticDEM data is constructed from in-track and cross-track high-resolution (~0.4 meter) imagery acquired by the Maxar constellation of optical imaging satellites. <br><br> To learn more about the ArcticDEM, please visit the Polar Geospatial Center's <a href="https://www.pgc.umn.edu/data/arcticdem/" target="_blank">ArcticDEM page</a> and <a href="https://www.pgc.umn.edu/guides/stereo-derived-elevation-models/pgcs-dem-products-arcticdem-rema-and-earthdem" target="_blank">DEM Product Guide</a>.

ArcticDEM项目由美国国家地理空间情报局（NGA）与国家科学基金会（NSF）共同发起，旨在利用光学立体影像、高性能计算和开源摄影测量软件，自动生成高分辨率、高质量的北极地区数字地表模型（DSM）。OpenTopography平台正在分发由所有ArcticDEM条带组装而成的ArcticDEM镶嵌图（版本4，2023年7月发布），以在大面积范围内提供一致且全面的产品。ArcticDEM数据由Maxar光学成像卫星星座在轨道内和轨道间获取的高分辨率（约0.4米）影像构建而成。<br><br>如需了解更多关于ArcticDEM的信息，请访问极地地理空间中心网站上的<a href="https://www.pgc.umn.edu/data/arcticdem/" target="_blank">ArcticDEM页面</a>和<a href="https://www.pgc.umn.edu/guides/stereo-derived-elevation-models/pgcs-dem-products-arcticdem-rema-and-earthdem" target="_blank">DEM产品指南</a>。
