Google Earth Engine——南极洲参考高程模型（REMA）是一个高分辨率、有时间戳的南极洲数字表面模型（DSM），具有2米和8米的空间分辨率

The Reference Elevation Model of Antarctica (REMA) is a high resolution, time-stamped Digital Surface Model (DSM) of Antarctica at 2-meter and 8-meter spatial resolutions.

Mosaicked DEM files are compiled from multiple strips that have been co-registered, blended, and feathered to reduce edge-matching artifacts.

南极洲参考高程模型（REMA）是一个高分辨率、有时间戳的南极洲数字表面模型（DSM），具有2米和8米的空间分辨率。

镶嵌的DEM文件是由多个条带汇编而成的，这些条带经过共同登记、混合和羽化，以减少边缘匹配的人工痕迹。
