Introduction

geonum is a python library written in Python 3 for geographic calculations. It provides intuitive objects for representing locations on Earth in terms of longitude, latitude and altitude, as well as associated arithmetics.

geonum was developed together with the pyplis library (python plume imaging software) to provide the required tools to derive the required measurement geometry (e.g., distance of camera to volcanic emission plume, see e.g. Gliss et al., 2017, Figure 3 therein).
