Planetary Test Data contains a list of planetary data for software testing
purposes and utilities to retrieve them.

* Free software: BSD license

Features
--------

* Downloads a core set of sample Planetary test data into
``./mission_data/`` or if ``./tests/mission_data/`` if ``./tests/`` exists.

TODO
------

* Download to central cache directory and use symbolic links to share data
between projects or other locations.
* Find smaller example images to reduce download times.
* Command line usage improvements

* Include a mode that just copies the ``data.json`` file into the local
directory.
* Include a mode that allows users to somehow specify subsets of data to
retrieve. Perhaps selecting by mission or instrument name.

* Improve label testing.
* Include Mission Names with each product.
* Include product type with each product.

See also the Github issues for this project.

Usage
------

To download the core set of planetary test data install this package with pip
and then run the command ``get_mission_data``::

pip install planetary_test_data
get_mission_data

Additional usage options are shown below::

usage: get_mission_data [-h] [--all] [--file FILE] [--dir DIR]
[--tags [TAGS [TAGS ...]]]

optional arguments:
-h, --help show this help message and exit
--all, -a Download all products.
--file FILE, -f FILE Override default data.json by providing path to custom
data.json file.
--dir DIR, -d DIR Directory to place test data products in.
--tags [TAGS [TAGS ...]], -t [TAGS [TAGS ...]]
Retrieve products whose tags match those provided
here.

Description
------------

Running ``get_mission_data`` will do the following

* If ``tests`` directory exists it will create ``tests/mission_data`` if
necessary. If ``tests`` does not exist, it will just create
``mission_data`` in the current directory.
* The data prodcuts tagged to be ``core`` products will be downloaded
into the download directory.

Only products which do not exist in the download directory will be
downloaded.

Mission Data
-------------

The PDS mission data included in the package can be found here::

https://github.com/planetarypy/planetary_test_data/blob/master/planetary_test_data/data.json

If there are products you think should be included or removed from this dataset
please file a Github issue.

data.json Format
-----------------

The ``data.json`` file contains PDS product names, urls and other
metainformation about the product. This structure will be extended to support
generic testing, for instance the ``label`` key will be changed to a
dictionary that includes product label keys and the values found at those keys.

Below is a sample snippet of a ``data.json`` entry::

"1m298459885effa312p2956m2m1.img": {
"instrument": "MICROSCOPIC IMAGER",
"label": "PDS3",
"opens": "True",
"url": "http://pds-imaging.jpl.nasa.gov/data/mer/opportunity/mer1mo_0xxx/data/sol1918/edr/1m298459885effa312p2956m2m1.img"
},
