ibcso_coverage(region=None)[source]#

Load IBCSO v2 data, from Dorschel et al.[1] and Dorschel et al.[2].

Parameters:

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:

Returns two geodataframes; points and polygons for a subset of IBCSO v2 point measurement locations. Column ‘dataset_tid’ is the type identifier from IBCSO. The points geodataframe contains all individual point measurements, including single-beam (TID 10), seismic points (TID 12), isolated soundings (TID 13), ENC sounding (TID 14), grounded iceberg draft (TID 46), and gravity-inverted bathymetry (TID 45). The polygon geodataframe contains all polygon measurements, including multi-beam (swath) (TID 11), contours from charts (TID 42), or other unknown sources (TID 71).

Return type:

tuple[GeoDataFrame, GeoDataFrame]
