Python MAAP Client Library

Python client library that abstracts MAAP API calls including CMR querying, algorithm change management, and HySDS job execution. CMR components in this library are largely derived from the pyCMR library.

Setup

Run:

$ python setup.py install

Or

$ pip install -e .

Usage

Populate your MAAP base url into a maap.cfg file, using maap.cfg as a template.

Then, run:

$ python
>>> from maap.maap import MAAP
>>> maap = MAAP() 

>>> granules = maap.searchGranule(sitename='lope', instrument='uavsar')
>>> for res in granules:
    print(res.getDownloadUrl())
    res.download()
#results omitted for brevity

Custom 'Named Attribute' Parameters

Named parameters are recommended as an alternative to CMR's additional attributes as a way to improve usability. This list of attributes is editable in the maap.cfg indexed_attributes setting. E.g.:

• "site_name,Site Name,string" where site_name is the parameter, Site Name is the CMR attribute name, and string is the parameter type.

With named attribute parameters, this query:

lidarGranule = maap.searchGranule(instrument='lvis', attribute='string,Site Name,lope')

Simplifies to:

lidarGranule = maap.searchGranule(instrument='lvis', site_name='lope')

Test

python setup.py test
