Subject [jira] [Commented] (CLIMATE-393) Add less strict subsetting functionality
Date Sat, 05 Apr 2014 02:58:15 GMT

ASF GitHub Bot commented on CLIMATE-393:
----------------------------------------

GitHub user MJJoyce opened a pull request:

    https://github.com/apache/climate/pull/10

    CLIMATE-393 - Add dataset_processor.safe_subset

    - Add safe_subset for gracefully handling subsetting when not all of the
      bounding parameters are fully contained in the target dataset. If any
      of the bounding values fall outside of the dataset's bounds they are
      defaulted to the dataset's maximum/minimum.

You can merge this pull request into a Git repository by running:

    $ git pull https://github.com/MJJoyce/climate CLIMATE-393

> The current subsetting functionality requires that the subregion be entirely in the bounds
of the dataset being subset. This can cause a number of problems, especially when dealing
with data where the information falls on fractional lat/lon grid values. It would be nice
to have a subset function that wouldn't error out if one or more of it's values are outside
of the dataset's bounds. Instead, it should return the overlap of the subset bounds and the
dataset's bounds.
