Unleashing the Power of Sports Activity Analysis: A Framework Beyond Ordinary Metrics 🚀

Prepare to dive into the thrilling world of sports activity analysis, where hidden geographic, topological, and personalized data await their grand unveiling. In this captivating journey, we embark on a quest to extract the deepest insights from the wealth of information generated by monitoring sports activities. Brace yourself for a framework that transcends the limitations of conventional analysis techniques. 💪🔍

Traditional approaches often rely on integral metrics like total duration, total distance, and average heart rate, but they fall victim to the dreaded "overall metrics problem." These metrics fail to capture the essence of sports activities, omitting crucial components and leading to potentially flawed and misleading conclusions. They lack the ability to recognize distinct stages and phases of the activity, such as the invigorating warm-up, the endurance-testing main event, and the heart-pounding intervals. ⏱️🚴‍♀️📈

Fortunately, our sport-activities-framework rises above these limitations, revealing a comprehensive panorama of your sports activity files. This framework combines the power of identification and extraction methods to unlock a treasure trove of valuable data. Picture this :camera: : effortlessly identifying the number of hills, extracting average altitudes of these remarkable formations, measuring the total distance conquered on those inclines, and even deriving climbing ratios for a true measure of accomplishment (total distance of hills vs. total distance). But that's just the tip of the iceberg! The framework seamlessly integrates a multitude of extensions, including historical weather parsing, statistical evaluations, and ex-post visualizations that bring your data to life. 🗻📊🌦️

For those seeking to venture further, we invite you to explore the realms of scientific papers on data mining that delve into these captivating topics. Discover how our framework complements the world of generating and predicting automated sport training sessions, creating a harmonious synergy between theory and practice. 📚🔬💡

🌦️ Historical weather data

Weather data parsed is collected from the Visual Crossing Weather API. Please note that this is an external unaffiliated service, and users must register to use the API. The service has a free tier (1000 Weather reports/day) but is otherwise operating on a pay-as-you-go model. For pricing and terms of use, please read the official documentation of the API provider.

🧩 Overpass API, Open Elevation API & OpenTopoData integration

Without performing activities, we can use the OpenStreetMap for the identification of hills, total ascent, and descent. This is done using the Overpass API which is a read-only API that allows querying of OSM map data. In addition to that altitude, data is retrieved by using the Open-Elevation API or OpenTopoData API which are open-source and free alternatives to the Google Elevation API. Both of the solutions can be used by using free publicly acessible APIs (Overpass, Open-Elevation, OpenTopoData) or can be self hosted on a server or as a Docker container (Overpass, Open-Elevation, OpenTopoData).
