AI-generated Key Takeaways
-
The Reference Elevation Model of Antarctica (REMA) provides a high-resolution Digital Surface Model (DSM) of Antarctica at 8-meter and 2-meter resolutions, timestamped between 2009 and 2018.
-
REMA data is compiled from multiple strips that are co-registered, blended, and feathered to minimize edge-matching artifacts.
-
This dataset is provided by the University of Minnesota Polar Geospatial Center and requires acknowledgement of NSF support and proper attribution in publications and media using the data.
-
Users can access and analyze REMA data through Google Earth Engine, a platform for petabyte-scale scientific analysis and visualization of geospatial datasets.
-
Researchers are encouraged to cite Howat et al.(2019) when using REMA data in their work.

Description
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.
