Features

Reads in PDS Images as NumPy arrays.

Supports GZIP and BZ2 compressed PDS Images.
Supports writing out PDS3 images.


Reads in Isis Cube Files as NumPy arrays.

Check out a few simple examples of
opening and viewing PDS and Isis CubeFiles in an IPython notebook.


Quickstart
The example below will walk you through setting up a Python virtual
environment and installing the necessary software as well as a few handy
extras. It then downloads a sample Pancam PDS image, opens and displays that
image in your web browser in an
IPython Notebook. The example assumes
you have Python, virtualenv, and pip installed on your system. If you
don’t, don’t know what this means or aren’t thrilled by the opportunity to
learn what this means, this software may be a little too immature for you to
use at this point.
Create and activate a virtual environment:
virtualenv venv
source venv/bin/activate
Upgrade pip, then pip install the package and IPython notebook and matplotlib
to help display the image:
pip install -U pip
pip install planetaryimage matplotlib ipython[notebook]
This quick example will show how to open and display a Pancam PDS image using
this module. First, grab a sample image:
wget http://pds-imaging.jpl.nasa.gov/data/mer/opportunity/mer1po_0xxx/data/sol2840/edr/1p380322615effbr43p2443l1m1.img
Now run python in an IPython Notebook (a browser window should pop up after
entering the following command):
$ ipython notebook
Create a new notebook in your web browser and then paste the following code
into a cell and execute it by pressing Shift+ENTER. This will load and display
the image:
%matplotlib inline
import matplotlib.pyplot as plt
from planetaryimage import PDS3Image
image = PDS3Image.open('1p380322615effbr43p2443l1m1.img')
plt.imshow(image.image, cmap='gray')
