Where is offline data stored in cartopy? Is it stored in the data folder under site-packages? Is there any way to trigger the downloading of all available data? I would like to copy this over to a Linux machine that is not connected to the internet. I'm currently working from a Windows machine that is connected to the internet, so I'm hoping to download the data from there. Thanks.
Take a look at the config docs in http://scitools.org.uk/cartopy/docs/latest/cartopy.html. Essentially, the data is downloaded to the data_dir
item in that config. For me that looks like:
>>> import cartopy.config
>>> cartopy.config['data_dir']
'/home/pelson/.local/share/cartopy'
Of course, that can be configured to wherever you like.
Because I also deploy cartopy to my organisation, we also configure cartopy to have centrally stored data. This is put in a location determined by the pre_existing_data_dir
config item.
Finally, to batch download all of the data (which is several GB), there is a script in the cartopy source at tools/feature_download.py. Running it to download all of the data is simply:
$> python tools/feature_download.py
Full help is available:
$> python tools/feature_download.py --help
usage: feature_download.py [-h] [--output OUTPUT] [--dry-run] [--ignore-repo-data] GROUP_NAME [GROUP_NAME ...]
Download feature datasets.
positional arguments:
GROUP_NAME Feature group name: cultural-extra, cultural, gshhs, physical
optional arguments:
-h, --help show this help message and exit
--output OUTPUT, -o OUTPUT
save datasets in the specified directory (default: user cache directory)
--dry-run just print the URLs to download
--ignore-repo-data ignore existing repo data when downloading
