      <description descriptionType="Abstract">This publication contains the software and data used in the analysis presented in the paper "Citizen science illuminates the nature of city lights". In the Nachtlichter project, citizen scientists went out at night and classified and counted light sources, reporting the data via an app. This publication contains a subset of that data, as well as software tools to compare the data to satellite data from the VIIRS DNB.   <br/>
