An overview of the Measuring Geographic Distributions toolset

Measuring the distribution of a set of features allows you to calculate a value that represents a characteristic of the distribution, such as the center, compactness, or orientation. You can use this value to track changes in the distribution over time or to compare distributions of different features.

The Measuring Geographic Distributions toolset addresses questions such as:

The following table lists the tools available and provides a brief description of each.

NOTE: Tool availability is determined by ArcGIS license. Licensing requirements for each tool are listed below.

Tool Description
Central Feature Identifies the most centrally located feature in a point, line, or polygon feature class. Available with any ArcGIS license.
Directional Distribution Measures how concentrated features are around the geographic mean and whether or not they exhibit a directional trend (whether features are farther from a specified point in one direction than in another direction). Available with any ArcGIS license.
Linear Directional Mean Identifies the general (mean) direction and mean length for a set of vectors. Available with any ArcGIS license.
Mean Center Identifies the geographic center, or the center of concentration, for a set of features. Available with any ArcGIS license.
Standard Distance Measures the degree to which features are concentrated or dispersed around the geographic mean center. Available with any ArcGIS license.
