Viewshed analysis using polygons in ArcGIS Desktop?
Hiking & ActivitiesWhat parameters can we choose for viewshed analysis?
A number of parameters can influence the result of a viewshed analysis including the viewpoint, the height of the observer, the viewing azimuth, the viewing radius, vertical viewing angle limits, the Earth’s curvature, and tree height.
What is viewshed analysis in ArcGIS?
A viewshed identifies the cells in an input raster that can be seen from one or more observation locations. Each cell in the output raster receives a value that indicates how many observer points can be seen from each location.
How do you calculate viewshed?
To calculate Viewshed Analysis, enable Viewshed Analysis mode, then add observer points in the Main window. The calculation is based on the location of the observer points, and the parameters set for those points.
The drop-down list options are:
- Geographic Lat/Lon.
- UTM.
- Geocentric (ECEF).
- Arbitrary.
