Summarize Incident Count (Crime Analysis and Safety Tools)

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.

Label	Explanation	Data type
Input Features	The input features to which coincident point counts will be calculated.	Feature Layer
Input Summary Features	The point features coincident with the input features.	Feature Layer
Output 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"

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