Label | Explanation | Data Type |
Input Point Features | The point features to use as the observer locations. | Feature Set |
Maximum Distance (Optional) | The maximum distance to calculate the viewshed. | Double |
Maximum Distance Units (Optional) | Specifies the units for the Maximum Distance parameter.
| String |
DEM Resolution (Optional) | Specifies the approximate spatial resolution (cell size) of the source elevation data used for the calculation. The resolution keyword is an approximation of the spatial resolution of the digital elevation model. Many elevation sources are distributed in units of arc seconds; the keyword is an approximation in meters for easier understanding.
| String |
Observer Height (Optional) | The height above the surface of the observer. The default value of 1.75 meters is an average height of a person. If you are looking from an elevated location such as an observation tower or a tall building, use that height instead. | Double |
Observer Height Units (Optional) | Specifies the units for the Observer Height parameter.
| String |
Surface Offset (Optional) | The height above the surface of the object you are viewing. The default value is 0. If you are viewing buildings or wind turbines, use their height. | Double |
Surface Offset Units (Optional) | Specifies the units for the Surface Offset parameter.
| String |
Generalize Viewshed Polygons (Optional) | Specifies whether the viewshed polygons will be generalized. The viewshed calculation is based on a raster elevation model that creates a result with stair-stepped edges. To create a more pleasing appearance and improve performance, the default behavior generalizes the polygons. This generalization will not change the accuracy of the result for any location more than one half of the DEM resolution.
