AI-generated Key Takeaways
-
REMA is a high-resolution Digital Surface Model (DSM) of Antarctica, available at 2-meter and 8-meter resolutions.
-
It offers both strip DEM files, representing raw data from image pairs, and mosaicked DEM files for a seamless, blended elevation model.
-
Strip DEMs show the overlapping areas of stereoscopic imagery, while mosaicked DEMs combine multiple strips, reducing artifacts.
-
REMA data is time-stamped, providing valuable insights into changes in the Antarctic landscape.

REMA Mosaic
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. dem elevation-topography geophysical pgc rema umn -
