Secondary and primary craters in and around the Copernicus crater

Primary craters are created by direct asteroid or comet impacts, while secondary craters form from debris ejected by these impacts. Secondary craters are records of large impact processes, causing errors in surface age estimation.A method utilizing spectral data to identify secondary craters on the lunar surface was developed, employing a deep learning model known as ResNet.

When applied to the area surrounding the Copernicus crater, the model accurately classified 285,071 secondary and 38,865 primary craters with diameters ranging from 200 m to 5 km.The catalog of secondary and primary craters in and around the Copernicus crater is stored in Shapefile format. The central coordinates (longitude and latitude) and diameters are listed in the attribute table of the Shapefile as Lon, Lat, and Dia, respectively, with units in degrees and meters.
