Esri ArcGIS Server GEOPROCESSING SERVICE Esri ArcGIS Server - SkyLineGraph

Geoprocessing service SkyLineGraph is a public service intended for visibility analysis using the digital terrain or digital surface model. The geoprocessing service enables the user to find out which area is visible from a chosen observer location up to a defined distance. The user can use the digital surface model of the 1st generation rasterised to 2 m resolution, the digital terrain model of the 4th generation rasterised to 2 m resolution, or the digital terrain model of the 5th generation rasterised to 5 m resolution. Selection of the input model is set in the "Model" parameter. It is necessary to choose the observer location, specify the observer offset above the terrain and define the distance within which the visibility analysis is required. The result of the analysis is a visibility field (area) represented by polygons delimiting the visible parts of the terrain. From the resulting table it is possible to create a graph of horizon coverage, which shows the extent of horizon coverage depending on the azimuth and the specified distance.
