An overview of the Visibility toolset

Available with 3D Analyst license.

The Visibility toolset features tools for performing various forms of visibility analysis, ranging from constructing shadow models and sight lines to generation of viewsheds and skylines.

License:

Certain Visibility tools are also available with a Spatial Analyst extension license. These tools are: Observer Points, Viewshed, Viewshed 2, and Visibility.

ToolDescription

Construct Sight Lines

Creates line features that represent sight lines from one or more observer points to features in a target feature class.

Intervisibility

Determines the visibility of sight lines against potential obstructions defined by any combination of 3D features and surfaces.

Line Of Sight

Determines the visibility of sight lines over obstructions consisting of a surface and an optional multipatch dataset.

Observer Points

Identifies which observer points are visible from each raster surface location.

Skyline

Generates a line or multipatch feature class containing the results from a skyline or silhouette analysis.

Skyline Barrier

Generates a multipatch feature class representing a skyline barrier or shadow volume.

Skyline Graph

Calculates sky visibility and generates an optional table and polar graph.

Sun Shadow Frequency

Calculates the number of times a fixed position on a surface has its direct sight line to the sun obstructed by multipatch features.

Sun Shadow Volume

Creates closed volumes that model shadows cast by each feature using sunlight for a given date and time.

Viewshed

Determines the raster surface locations visible to a set of observer features.

Viewshed 2

Determines the raster surface locations visible to a set of observer features using geodesic methods

Visibility

Determines the raster surface locations visible to a set of observer features, or identifies which observer points are visible from each raster surface location.
