Multifactorial methodology of cycling routes time calculation based on 3D maps

Modern sports tourism is being transformed under the influence of world tourism trends. The creation of clear and convenient routes will allow for more organized tourism activities and reduce the chaotic load on the natural environment. Based on the analysis of applications for planning and tracking routes, the article proposes a multifactor method for calculating time, which allows you to develop clear and well-constructed tourist routes and solve specific problems, including taking into account weather conditions, terrain and various categories of participants. This article focuses on the methodology for calculating the time of passage of multi-day cycling routes in three main categories: mountainous terrain, flat terrain with water obstacles and a route crossing the state border. The proposed methodology solves the problem of symbiosis between geography and tourism practice.
