Central Feature

How to use Central Feature Tool in Arc Toolbox??

Central Feature

Path to access the tool

:

Central Feature Tool, Measuring Geographic Distribution Toolset, Spatial Statistics Tools Toolbox

Central Feature

Identifies the most centrally located feature in a point, line, or polygon feature class.

1. Input Feature Class

The feature class containing a distribution of features from which to identify the most centrally located feature.

2. Output Feature Class

The feature class that will contain the most centrally located feature in the Input Feature Class.

3. Distance Method

Specifies how distances are calculated from each feature to neighboring features.

1. EUCLIDEAN_DISTANCE—The straight-line distance between two points (as the crow flies)
2. MANHATTAN_DISTANCE—The distance between two points measured along axes at right angles (city block); calculated by summing the (absolute) difference between the x- and y-coordinates

4. Weight Field (optional)

The numeric field used to weight distances in the origin-destination distance matrix.

5. Self Potential Weight Field (optional)

The field representing self-potential—the distance or weight between a feature and itself.

6. Case Field (optional)

Field used to group features for separate central feature computations. The case field can be of integer, date, or string type.

Directional Distribution (Standard Deviational Ellipse)

How to use Directional Distribution (Standard Deviational Ellipse) Tool in Arc Toolbox??

Directional Distribution (Standard Deviational Ellipse)

Directional Distribution (Standard Deviational Ellipse)

Creates standard deviational ellipses to summarize the spatial characteristics of geographic features: central tendency, dispersion, and directional trends.

1. Input Feature Class

A feature class containing a distribution of features for which the standard deviational ellipse will be calculated.

2. Output Ellipse Feature Class

A polygon feature class that will contain the output ellipse feature.

3. Ellipse Size

The size of output ellipses in standard deviations. The default ellipse size is 1; valid choices are 1, 2, or 3 standard deviations.

• 1_STANDARD_DEVIATION
• 2_STANDARD_DEVIATIONS
• 3_STANDARD_DEVIATIONS

4. Weight Field (optional)

The numeric field used to weight locations according to their relative importance.

5. Case Field (optional)

Field used to group features for separate directional distribution calculations. The case field can be of integer, date, or string type.

Linear Directional Mean

How to use Linear Directional Mean Tool in Arc Toolbox??

Linear Directional Mean

Linear Directional Mean

Identifies the mean direction, length, and geographic center for a set of lines.

1. Input Feature Class

The feature class containing vectors for which the mean direction will be calculated.

2. Output Feature Class

A line feature class that will contain the features representing the mean directions of the input feature class.

3. Orientation Only

Specifies whether to include direction (From and To nodes) information in the analysis.

1. Checked—The From and To node information is ignored.
2. Unchecked—The From and To nodes are utilized in calculating the mean. This is the default.

4. Case Field (optional)

Field used to group features for separate directional mean calculations. The case field can be of integer, date, or string type.

Mean Center
