Planet Four: Probing springtime winds on Mars by mapping the southern polar CO2 jet deposits

This paper describes the reduction pipeline of surface markings of the Citizen Science project Planet Four into a catalog of geo-located fan and blotch objects. Planet Four enlists the general public to map the shapes, directions, and sizes of the seasonal fans visible in orbital images. Over 80,000 volunteers have contributed to the Planet Four project, reviewing 221 images, from Mars Reconnaissance Orbiter’s HiRISE (High Resolution Imaging Science Experiment) camera.
