Ski lift transportation data that offers a huge potential for improving services and developing new products in ski resorts. Building models from data was always an inspiration and thrust for me. This project is a pioneer endeavor that extracts patterns from skier movement data. After so many years of studying this data it is time to move the models from labs to reality!

All of the work are done on the Mt. Kopaonik ski resort, Serbia. Big thank to Mountain Ski Rescue Service who provided us with data!
