GlacierDirectory
(rgi_entity, base_dir=None, reset=False, from_tar=False, delete_tar=False)[source]¶ Organizes read and write access to the glacier’s files.
It handles a glacier directory created in a base directory (default is the “per_glacier” folder in the working directory). The role of a GlacierDirectory is to give access to file paths and to I/O operations. The user should not care about where the files are located, but should know their name (see cfg.BASENAMES).
If the directory does not exist, it will be created.
See Glacier directories for more information.
Attributes: - dir : str
path to the directory
- rgi_id : str
The glacier’s RGI identifier
- glims_id : str
The glacier’s GLIMS identifier (when available)
rgi_area_km2
: floatThe glacier’s RGI area (km2).
- cenlon, cenlat : float
The glacier centerpoint’s lon/lat
- rgi_date : int
The RGI’s BGNDATE year attribute if available. Otherwise, defaults to the median year for the RGI region
- rgi_region : str
The RGI region name
- name : str
The RGI glacier name (if Available)
- glacier_type : str
The RGI glacier type (‘Glacier’, ‘Ice cap’, ‘Perennial snowfield’, ‘Seasonal snowfield’)
- terminus_type : str
The RGI terminus type (‘Land-terminating’, ‘Marine-terminating’, ‘Lake-terminating’, ‘Dry calving’, ‘Regenerated’, ‘Shelf-terminating’)
- is_tidewater : bool
Is the glacier a caving glacier?
- inversion_calving_rate : float
Calving rate used for the inversion
-
__init__
(self, rgi_entity, base_dir=None, reset=False, from_tar=False, delete_tar=False)[source]¶ Creates a new directory or opens an existing one.
Parameters: - rgi_entity : a
geopandas.GeoSeries
or str glacier entity read from the shapefile (or a valid RGI ID if the directory exists)
- base_dir : str
path to the directory where to open the directory. Defaults to cfg.PATHS[‘working_dir’] + /per_glacier/
- reset : bool, default=False
empties the directory at construction (careful!)
- from_tar : str or bool, default=False
path to a tar file to extract the gdir data from. If set to True, will check for a tar file at the expected location in base_dir.
- delete_tar : bool, default=False
delete the original tar file after extraction.
- rgi_entity : a
