OT Collection Name: Reference Elevation Model of Antarctica (REMA)
Short Name: REMA32m, REMA10m, REMA2m
Collection Platform: Satellite Data
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.
