Python module to read NASA Planetary Data System v3 files or data. These functions are rudimentary, and should not be used for validation.
Requires: numpy, astropy, ply.
Time fields are assumed to be on the UTC scale. I haven't verified if that assumption is valid for PDS3.
ASCII tables can be read, and there is some support for 2D images. Binary table reading is experimental (pds3.core.read_binary_table).
Problems? Please open an issue, or submit a pull request with updated code.

Read your label into the experimental PDS3Label class and access
key values via indexing:
lbl = PDS3Label('product.lbl')
r = lbl['RECORD_LENGTH']
shape = lbl['IMAGE']['LINES'], lbl['IMAGE']['LINE_SAMPLES']Print the full label as a string:
print(lbl)I've tested round-tripping a short label from the International Halley Watch archive and it worked, but more testing is needed.
I hope you find pds3 useful, but use at your own risk.
pds3 does not validate files, may work for invalid files, and may not work for valid files.
