PlanetMapper: A Python package for visualising, navigating and mapping Solar System observations

PlanetMapper is an open source Python package to visualise, process and understand astronomical observations of Solar System objects, such as planets, moons and rings. Astronomers can use PlanetMapper to ‘navigate’ observations by calculating coordinate values (such as latitude and longitude) for each pixel in an observed image, and can map observations by projecting the observed data onto a map of the target body. Calculated values are exportable and directly accessible through a well documented API, allowing PlanetMapper to be used for custom analysis and processing. PlanetMapper can also be used to help generate publication quality figures, and has a Graphical User Interface to significantly simplify the processing of astronomical data. PlanetMapper can be applied to a wide range of datasets, including both amateur and professional ground-based observations, and data from space telescopes like Hubble and JWST.
