Reference Elevation Model of Antarctica (REMA) provides the first, high resolution (8-meter) terrain map of nearly the entire continent. Adding this might help better resolve bed elevation since surface elevation does correlate with the bed elevation.

TODO:

  • Get full Antarctic Continent 200m mosaic in geotiff format (6a20d1c)
  • Work out web-based (e.g. WMS) way to get REMA data (TODO check https://www.pgc.umn.edu/data/rema/ when ImageService is up!)
  • Incorporate REMA data into the SRCNN model (f0e664a)

🍱 Add 200m REMA surface DEM mosaic
6a20d1c 
Scripts to manually download and process the Reference Elevation Model of Antarctica (REMA) v1 geotiff file as part of #8. Had to rename the tiling functions (regular and selective tile). More confusingly is the change of X to Y and Y to X. X is now the low resolution input, and Y is the high resolution groundtruth. W is currently used for REMA, and we may change to using W1, W2, W3 and so on once we add in other relevant datasets #9.

🔒 Create csv table with url link and sha256 checksum of data files
b55a7c7 
Getting serious with data integrity. Explicitly listing all the data files with their SHA256 checksums (required) and their download URL (if available). Note only the Pine Island Glacier datasets are missing URL. Links upstream to #7, #8, #20, #21.

📝 Update literature and data citation DOIs for misc datasets
bd22369 
Relates to #8, #20. Adding in the persistent digital object identifier for the REMA dataset. Point to literature by Noh and Howat 2018, and also the dataset DOI. Also changed the MEaSUREsV2 dataset to point to the DOI link instead of NSIDC.

🍱 Bump REMA surface DEM from v1.0 to v1.1, 200m to 100m resolution
b04479d 
Increasing spatial resolution of our Antarctic surface digital elevation model! There is finally a 100m mosaic product for the whole continent. Note that the dataset doi (currently linking to Harvard Dataverse) is still at v1.0.

From the 'release notes' at https://www.pgc.umn.edu/data/rema/:

REMA Release 1.1 corrects 2 minor issues in the mosaic tiles:

    (1) A vertical offset of 39 cm was added to the 1086 8-m mosaic tiles registered to Cryosat-2 altimetry, as well as Antarctica-wide mosaics, to correct for biases induced by surface penetration and surface re-tracking. This correction was determined through comparison to ICESat-1 altimetry.

    (2) Incorrect No Data values were replaced in 288 of the 8-m mosaic tiles and the Antarctica-wide mosaics.

Supersedes #8.
