Sun Shadow Frequency (3D Analyst)—ArcGIS Pro

Summary

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

Illustration

Usage

The sun position will be calculated from the start date and time to the end date and time. If a time interval is specified, the sun position will be iteratively calculated from the start time to the end time for each day between the start date and end date. Any time the sun is not above the horizon will be skipped.
The output raster's cell values represent the number of times a given cell is in a shadow. The maximum possible value for any cell corresponds to the number of times the sun is positioned above the horizon.
Consider defining a maximum shadow length when generating results for sun inclination angles near sunrise and sunset to avoid factoring the impact of long shadow footprints. Enforcing a distance also helps improve tool performance.

Parameters

Label	Explanation	Data Type
Input Features	The multipatch features that will constitute the source of obstruction for sunlight.	Feature Layer
Ground Surface	The raster ground surface that will define the positions where sunlight obstruction will be evaluated.	Raster Layer
Output Shadow Raster	The output raster whose cell values reflect the number of times the corresponding ground height position was obstructed by the input features.	Raster Dataset
