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> Polar Geospatial Center https://www.pgc.umn.edu/ originator National Science Foundation https://nsf.gov/ resourceProvider National Geospatial-Intelligence Agency https://www.nga.mil/ resourceProvider null info@opentopography.org https://opentopography.org distributor en geoscientificInformation -179.99607141594248 179.99592587489337 -89.0805361872961 -53.54447496875338 https://doi.org/10.5069/G9X63K5S HTTP Standard Internet browser Download Navigate directly to the URL for data access and download.
