Python module to read NASA Planetary Data System v3 files.

pds3 v0.2.2

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.

Usage

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.

Caution

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.
