---------------------------------------
Summary: Add Subset Generation function to dataset_processor module
Key: CLIMATE-237
URL: https://issues.apache.org/jira/browse/CLIMATE-237
Project: Apache Open Climate Workbench
Issue Type: Sub-task
Components: rcmet
Affects Versions: 0.1-incubating
Environment: *nix
Reporter: Cameron Goodale
Assignee: Cameron Goodale
Fix For: 0.2-incubating
It has been discussed to have a subsetting capability added into OCW. The
logic place for this would be in the dataset_processor module.
The initial design is to take in a list of datasets and a subset options
dictionary. Example of calling the function is given below:
{code}
from dataset import Dataset
import dataset_processor as dsp
# build up 2 datasets
ds1 = Dataset(....)
ds2 = Dataset(....)
#declare the subsetting options you want to use
subset_options = {'latMin' : 10, 'latMax' : 20,
'lonMin' : -130, 'lonMax': -90,
'startDate' : datetime.datetime(2000,1,1),
'endDate' : datetime.datetime(2010,12,31)}
ds1_subsetted, ds2_subsetted = dsp.subset([dataset_one, dataset_two],
subset_options)
{code}
The ds1_subsetted and ds2_subsetted variables are just Dataset objects that
comply with the subset options. The returned datasets will come back in the
same order they were given.
