Landscape Visibility Analysis and their Visualisation

Popis výsledku v původním jazyce

Visibility analysis or Viewshed is a common function of almost all GIS systems. The aim of this project is to find out the best solution, to compute viewshed for the Olomouc region and ensure the best way of visualisation of the results. The first step to analyze the visibility is making a high quality Digital Terrain Model, choice of the best interpolation method and subsequent addition of vegetation and man-made structures layer. Visibility calculation is contained in a large number of software applications, but not all are able to compute visibility for a large area, so the choice of software was also very important. Currently there are many ways to transmit the analysis results to the target user. One of them is the use of Google Earth. The project deals with the possibilities of exporting the output from the visibility analysis from ArcGIS system to Google Earth. An important part is to optimize the size of the resulting layer using various methods of generalization so that the resulting layer is sufficiently precise and not too voluminous at the same time. The project also explores the possibilities of enrichment of visualization with multimedia content, which can be for example 3D models of buildings, photos, videos or spherical panoramas as we know from Google Street View, etc. The output of the project is an interactive application that will ensure a simple and visually attractive approach to data that represent the visibility of the most important observation points in the area of interest.
