polartoolkit.fetch.bedmap_points

bedmap_points(version, region=None)

Load bedmap point data, choose from Bedmap 1, 2 or 3 or all combined.

All elevations are in meters above the WGS84 ellipsoid.

version == ‘bedmap1’ from Lythe and Vaughan[1]. accessed from https://data.bas.ac.uk/full-record.php?id=GB/NERC/BAS/PDC/01619

version == ‘bedmap2’ from Fretwell et al.[2]. accessed from https://data.bas.ac.uk/full-record.php?id=GB/NERC/BAS/PDC/01616

version == ‘bedmap3’ from Fremand et al.[3]. accessed from https://data.bas.ac.uk/full-record.php?id=GB/NERC/BAS/PDC/01614#access-data download link was found from https://ramadda.data.bas.ac.uk/repository/entry/show?entryid=61100714-1e32-44af-a237-0a517529bc49 under DOI/BEDMAP3 datapoints, right click on the download link and copy link address

Parameters:

• version (str) – choose between ‘bedmap1’, ‘bedmap2’, ‘bedmap3’, or ‘all’, point data

• region (tuple[float, float, float, float] | None) – region to clip the loaded grid to, in format [xmin, xmax, ymin, ymax], by default doesn’t clip

Returns:

Return a dataframe, optionally subset by a region

Return type:

DataFrame
