This repository contains parsed metadata for all of the images in the Cassini ISS Online Data Volumes. This makes it possible to analyze the metadata surrounding the Cassini images without downloading hundreds of gigabytes of actual imagery.
Each volume of the original dataset is given its own newline-delimited JSON file. The field names are the keywords described in the ISS Data User's Guide.
The overall approach was inspired by Jon Keegan's cassini-tools, but the code is original.
