Summarize Attributes (GeoAnalytics Desktop)

Summary

Calculates summary statistics for fields in a feature class.

Parameters

Dialog

Label	Explanation	Data Type
Input Layer	The point, polyline, or polygon layer to be summarized.	Table View
Output Table	A new table with the summarized attributes.	Table
Fields	A field or fields used to summarize similar features. For example, if you choose a single field called PropertyType with the values of commercial and residential, all of the fields with the value residential fields will be summarized together, with summary statistics calculated, and all of the fields with the value commercial will be summarized together. This example will results in two rows in the output, one for commercial, and one for residential summary values. You can optionally select no fields and summarize all features in a single summary result.	Field
Summary Fields (Optional)	The statistics that will be calculated on specified fields.	Value Table
Time step interval (Optional)	A value that specifies the duration of the time step. This parameter is only available if the input points are time enabled and represent an instant in time. Time stepping can only be applied if time is enabled on the input.	Time Unit
Time step repeat (Optional)	A value that specifies how often the time-step interval occurs. This parameter is only available if the input points are time enabled and represent an instant in time.	Time Unit
Time step reference (Optional)	A date that specifies the reference time with which to align the time steps. The default is January 1, 1970, at 12:00 a.m. This parameter is only available if the input points are time enabled and represent an instant in time.	Date

Python

arcpy.gapro.SummarizeAttributes(input_layer, out_table, fields, {summary_fields}, {time_step_interval}, {time_step_repeat}, {time_step_reference})

Name	Explanation	Data Type
input_layer	The point, polyline, or polygon layer to be summarized.	Table View
out_table	A new table with the summarized attributes.	Table
fields [fields,...]	A field or fields used to summarize similar features. For example, if you choose a single field called PropertyType with the values of commercial and residential, all of the fields with the value residential fields will be summarized together, with summary statistics calculated, and all of the fields with the value commercial will be summarized together. This example will results in two rows in the output, one for commercial, and one for residential summary values. You can optionally select no fields and summarize all features in a single summary result.	Field
summary_fields [summary_fields,...] (Optional)	The statistics that will be calculated on specified fields. COUNT—The number of nonnull values. It can be used on numeric fields or strings. The count of [null, 0, 2] is 2. SUM—The sum of numeric values in a field. The sum of [null, null, 3] is 3. MEAN—The mean of numeric values. The mean of [0,2, null] is 1. MIN—The minimum value of a numeric field. The minimum of [0, 2, null] is 0. MAX—The maximum value of a numeric field. The maximum value of [0, 2, null] is 2. STDDEV—The standard deviation of a numeric field. The standard deviation of [1] is null. The standard deviation of [null, 1,1,1] is null. VAR—The variance of a numeric field in a track. The variance of [1] is null. The variance of [null, 1,1,1] is null. RANGE—The range of a numeric field. This is calculated as the minimum value subtracted from the maximum value. The range of [0, null, 1] is 1. The range of [null, 4] is 0. ANY—A sample string from a field of type string.	Value Table
time_step_interval (Optional)	A value that specifies the duration of the time step. This parameter is only available if the input points are time enabled and represent an instant in time. Time stepping can only be applied if time is enabled on the input.	Time Unit
time_step_repeat (Optional)	A value that specifies how often the time-step interval occurs. This parameter is only available if the input points are time enabled and represent an instant in time.	Time Unit
time_step_reference (Optional)	A date that specifies the reference time with which to align the time steps. The default is January 1, 1970, at 12:00 a.m. This parameter is only available if the input points are time enabled and represent an instant in time.	Date

Code sample

SummarizeAttributes example (stand-alone script)

The following stand-alone script demonstrates how to use the SummarizeAttributes tool.

# Name: Summarize Attributes.py
# Description: Summarize Crime Data by year and beat.

# Import system modules
import arcpy

arcpy.env.workspace = "C:/data/CityData.gdb"

# Set local variables
inFeatures = "ChicagoCrimes"
summaryFields = ["Year", "Beat"]
summaryStatistics = [["Arrest", "COUNT"], ["District", "COUNT"]]
out = 'SummarizeCrimes'

# Execute SummarizeAttributes
arcpy.gapro.SummarizeAttributes(inFeatures, out, summaryFields, 
                                summaryStatistics)
