Description

We improve approaches to quantify the global spatial randomness of impact craters by applying geodesic measurements. The data is structured as follows: 01_Script - Python 2.* script to conduct global randomness analyses of impact craters - Description of the variables to be changed in the Python script 02_Results - Contains the results of the randomness analysis of global crater data sets (Mercury, Venus, and the Moon) in the form of histogram and map plots, as well as Z-score plots Global crater data sets are available here: Mercury (Fassett et al., 2011): http://www.planetary.brown.edu/html_pages/mercury_craters.htm Mercury (Orgel et al., 2020): http://dx.doi.org/10.17632/vf2sfbdvzr.1 Venus (USGS Venus Crater Database): https://astrogeology.usgs.gov/search/map/Venus/venuscraters Moon (Robbins et al., 2018): https://astrogeology.usgs.gov/search/map/Moon/Research/Craters/lunar_crater_database_robbins_2018
