Reference Elevation Model of Antarctica (REMA) 10m

<p>The Reference Elevation Model of Antarctica (REMA) is part of a NGA-NSF public-private initiative to automatically produce high-resolution, high quality, digital surface models (DSMs) of the polar regions using optical stereo imagery, high-performance computing, and open source photogrammetry software. OpenTopography is distributing the REMA mosaics (version 2, released in October 2022) that are that are assembled from multiple REMA strips with the intention of providing a more consistent and comprehensive product over large areas. REMA data is constructed from in-track and cross-track high-resolution (~0.5 meter) imagery acquired by the Maxar constellation of optical imaging satellites.</p> <p>To learn more about the REMA, please visit the Polar Geospatial Center's <a href='https://www.pgc.umn.edu/data/rema/' target="_blank">REMA 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>.</p>

南极参考高程模型（REMA）系国家地理空间情报局（NGA）- 国家科学基金会（NSF）一项公共-私营合作项目的组成部分，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、数字地表模型（DSM）。OpenTopography正分发REMA镶嵌图（版本2，于2022年10月发布），这些镶嵌图由多个REMA条带汇编而成，旨在为大面积区域提供更加一致和全面的产品。REMA数据由Maxar光学成像卫星星座在轨道内和轨道交叉处获取的高分辨率（约0.5米）影像构建而成。欲了解更多关于REMA的信息，请访问极地地理空间中心的相关页面（[REMA页面](https://www.pgc.umn.edu/data/rema/)）和[DEM产品指南](https://www.pgc.umn.edu/guides/stereo-derived-elevation-models/pgcs-dem-products-arcticdem-rema-and-earthdem/)。
