Summarize Incident Count (Crime Analysis and Safety)

Summary

Creates a feature class with coincident point counts. Coincident point counts for line and point features are determined by a specified maximum distance. Point counts for polygon features are determine by whether point features or portions of features overlap with the polygon feature.

Usage

• The TOTAL_CNT field is created by the tool and includes a total count of all unique values for the Input Summary Features that are coincident with the Input Features.

  A field is created for each unique value found in the Group Field when the Group Field parameter is used. Each field contains a count of Input Summary Features that are coincident with the Input Features and have a matching unique value.

• The output feature class is symbolized using the TOTAL_CNT field.

• When the Group Field parameter is used, additional<value name>_CNT fields are created. The tool will generate a unique field name for every unique value of the attribute. If null values exist the None_CNT field is created.

Syntax

SummarizeIncidentCount(in_features, in_sum_features, out_feature_class, {search_radius}, {group_field})

Parameter	Explanation	Data Type
in_features	The input features to which coincident point counts will be calculated.	Feature Layer
in_sum_features	The point features coincident with the input features.	Feature Layer
out_feature_class	The output choropleth count feature class, symbolized by total count.	Feature Class
search_radius (Optional)	The maximum distance from an Input Features point or line that a point feature will be considered coincident. This parameter is not active when the Input Features is a polygon.	Linear Unit
group_field (Optional)	A field containing the value used to split point counts. Additional fields containing counts for each unique value in the group field will be generated.	Field

Code sample

SummarizeIncidentCount example 1 (Python window)

The following Python script demonstrates how to use the SummarizeIncidentCount function in immediate mode.

import arcpy
arcpy.env.workspace = r"C:/data/city_pd.gdb"
arcpy.ca.SummarizeIncidentCount("Precincts",
                                "Arrests",
                                "arrests_by_precinct_offense_type",
                                None,
                                "OFFENDESC")

SummarizeIncidentCount example 2 (stand-alone script)

The following Python script demonstrates how to use the SummarizeIncidentCount function in a stand-alone script.

# Name: SummarizeIncidentCount.py
# Description: Creates a polygon feature class containing the total number of 
#              crimes committed, the total number of each type of crime 
#              committed, within each precinct.

# Import system modules
import arcpy

# Set environment settings
arcpy.env.workspace = r"C:\data\city_pd.gdb"

# Execute SummarizeIncidentCount
arcpy.ca.SummarizeIncidentCount("Precincts", "Crimes", 
                                "crimes_by_precinct_offense_type", "OFFENDESC")
