Here is where I keep a variety of useful tools and code I have helped develop in the process of working with planetary science data. The latest can always be found at my github.
These tools are freely-available to use. If they are helpful to you, please send me a copy of any publication they are used in (ugschneck@gmail.com).
PYDAR: python library to access Cassini RADAR data

centerline-width: python library to map the centerline and width of a river (adaptation of Golly et al. 2017 with modifications for extreme meandering and large rivers)
