Esri ArcGIS Server GEOPROCESSING SERVICE Esri ArcGIS Server - SkyLineGraph

Geoprocessing service SkyLineGraph is a public service intended for visibility analysis execution using the digital terrain or digital surface model. The geoprocessing service enables to find out, which area is visible from a chosen observer location to defined distance. User can use digital surface model of the 1st generation rasterized to 2 m resolution, digital terrain model of the 4th generation rasterized to 2 m resolution, or digital terrain model of the 5th generation rasterized to 5 m resolution. Selection of the input model is set in "Model" parameter. It is necessary to choose the observer location, specify oberver offset above the terrain and define the distance, which the visibility analysis is demanded in. The result of the analysis is visibility field (area) represented by polygons, which delimits 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.
