Collect sample data.

[godber]

We need to collect a decent set of sample data to ensure that the library is robust. I started this in my gdal_pds repo, it grabs some MER data, but its all very similar:

https://github.com/godber/gdal_pds/blob/master/get_test_data.py https://github.com/godber/gdal_pds/blob/master/data.json

I'd really like to see data from every PDS Image Node mission represented.

[godber]

For each data product collected we should implement at the very least minimal "load" test.

I'd also like to point out the availability of AstroPy's download_file utility that includes caching: http://docs.astropy.org/en/stable/utils/index.html#file-downloads

I don't want AstroPy as a required dependency for this package as a whole, but an optional dependency or a development dependency would be fine.

This might be something we should make a call out to the community for ... aka twitter ...

Start off by making a list of Missions that have image data on the PDS Imaging Node:

• http://pds-imaging.jpl.nasa.gov/
• http://pds-imaging.jpl.nasa.gov/volumes/

Then add instruments to that list. Note that a mission/spacecraft may have multiple imaging products.

Then add links to sample products to the instruments in that list.

Keep this list initially in a wiki page here or in a github checklist comment in the ticket.

Some sample pds2isis commands that could be useful to convert from one filetype to another:

pds2isis from=pds3_1band.IMG to=1band_detached.cub+Tile+Lsb+Detached
pds2isis from=pds3_1band.IMG to=1band_detached.cub+Tile+Lsb+Attached
pds2isis from=pds3_1band.IMG to=1band_detached.cub+BandSequential+Lsb+Attached
pds2isis from=pds3_1band.IMG to=1band_detached.cub+BandSequential+Msb+Attached
pds2isis from=pds3_1band.IMG to=1band_detached.cub+UnsignedByte+0.0:0.0+BandSequential+Msb+Attached

Should I test the images with only PDS3Imgage.open()? If not then what else should I test them with? Or should I not worry on if they work or not?

[godber]

Testing with PDS3Image.open() is the first step after generating the data.json. So yeah. Do you have the data.json?

[godber]

@pbvarga1 I am going to declare this task done, as other tasks will more fully satisfy the remaining requirements. Mostly when you create a full data.json in the planetary_test_data package.
