Feature Statistics

Purpose

The tool is provided for calculating basic statistics for point, multipoint, polyline and polygon features.

Description

Feature Statistics tool allows to easily gather selectable set of basic feature statistics for a given feature class of any geometry type with various output options.

Calculating feature statistics

Select the "Feature Statistics" tool from the XTools Pro Table Operations menu.
Select input features for gathering basic statistics.
Select required output option and specify the name and location of the output table or feature class.
Select statistics parameters to calculate and modify default field names if required.
Press Run.

There are following output options available:

Add statistics to input dataset
attribute fields with calculated statistics will be added to the input dataset

Create new table
a new table with fields containing calculated statistics will be created

Create new feature class with extents
a new feature class with input feature extents will be created, fields with calculated statistics will be added to the attribute table

Statistics parameters and applicable geometry types are given in the table below (direction calculation method can be customized in XTools Pro Options):
