Planetary Test Data

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 ./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 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

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.
• Use the -a or --all flag to get all the images. This, however, is NOT recommended for you will download over 200 images and labels.
• The -t or --tags will retrieve products matched with the supplied tag. To give multiple tags, use the flag multiple times.
• The -d or --dir flag can be used to save the images in a new custom location.
• If there exists a custom data.json locally and you would rather use that file to download images rather than the default, use the -f or --file flag and then the path to the data.json. This is especially useful if there are test images needed that do not exist in or are not part of the core in the default data.json (see get_mission_json below).
• To get products by mission use the --mission or -m flag. This will download all the products from the given mission, even non core products, unless explicity given core as a tag. To specify multiple missions, use the flag multiple times. You must spell the mission the same as spelled in Missions and Instruments (case matters!).
• To get products by instruments use the --instruments or -i flag. This will download all the products from the given instrument, even non core products, unless explicity given core as a tag. To specify multiple instruments, use the flag multiple times. You must spell the instrument the same as spelled in Missions and Instruments (case matters!).
• Only products which do not exist in the download directory will be downloaded.

Running get_mission_json will do the following:

• Create a copy of data.json in the tests or test directory. This will just be the core data by default. The purpose of getting a copy of the data.json is so it is easier to include images in respective projects that are not included in the default data.json. Then developers can use the -f flag on get_mission_data (see above) to use this custom data.json.
• If data.json already exists, an exception is raised.
• The same flags apply to get_mission_json as get_mission_data.

Mission Data

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

The following are core products:

• 0047MH0000110010100214C00_DRCL.IMG
• 0047MH0000110010100214C00_DRCL.LBL
• 1p134482118erp0902p2600r8m1.img
• 1p190678905erp64kcp2600l8c1.img
• 2p129641989eth0361p2600r8m1.img
• 2m132591087cfd1800p2977m2f1.img
• h58n3118.img
• r01090al.img

If there are products you think should be included or removed from this dataset please file a Github issue. New images should be images from instruments that are not already included or different file types (i.e. EDR vs RDR). New core images should be distinctly different than the ones that exist and would expose test and/or edge cases for multiple PlanetaryPy projects/affiliates. For example, if there was not an RGB image included in the core products (which there is), then that would test image would expose an edge case for many projects. However, it is best to use get_mission_json to get a copy of data.json, add the desired test images to that json file, and then download images using get_mission_data -f path/to/data.json. We recommend using a make test command to get the proper mission data before testing.

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"
},
