Hi ncc1701d!

Here is a link to an interactive demonstration of planetocentric and planetographic coordinates. It is part of the ISIS workshop which contains a wealth of information in a well explained maner.

In ISIS I found this bit of code for planetographic to planetocentric convertion: https://isis.astrogeology.usgs.gov/IsisSupp...hp?topic=1550.0
