Abstract
Authors of the research propose the methodology for studying conditions of the pedestrian infrastructure by applying advanced geoinformation technologies. The known algorithms of computing the raster maps of the cost of travelling, speed of pedestrians’ walking in the mountainous area by applying the Tobblers’ hiking functions, and development of the isochrone maps are supplemented with the high-resolution models of the area. These models include orthophotos, digital models of the visible surface, and a raster model of the relief, which are created basing on the materials of aerial surveying with unmanned aerial vehicles. The data about the underlying surface are obtained from aerial images, and the map of obstacles for travelers – also from aerial images and cadastral maps. Noteworthy is the fact that modern technologies of aerial surveying with UAV enable creating highly detailed digital models of the area, which are suitable for engineering tasks, but are excessively detailed for the landscape study. Thus, there is a need to perform additional program procedures for generalization of the relief model for the goal of routing. When archive materials of aerial surveying are available, there is a technical possibility to compare efficiency of the engineering arrangement of the recreation zone, particularly changes in the conditions of the route passing, efficiency of designing the viewing platforms and parking areas, etc. The recreation zone in Skhidnytsia resort-town located in Carpathians was chosen as the research object.
