Incident Analysis Tools

These tools help you discover spatial patterns and trends in significant activity in your area of interest.

• Cluster Analysis
• Count Incidents By LOC
• Find Percent Change
• Hot Spots By Area
• Incident Density
• Incident Hot Spots
• Incident Table To Point

These tools are part of the Incident Analysis Template

Landsat Tools

These tools help to pre-process Landsat 5 and 7 data to prepare it for Change Detection. The toolbox includes:

• DN to Reflectance
• Landsat 7 Gap Filler
• LTK Cloud Detector
• ACCA Cloud Detector

The toolset is based upon the ArcGISScriptTools by Jerrod Lessel: https://github.com/jerrod-lessel/ArcgisScriptTools

Change Detection Tools

These tools help you to identify change in your image. There are a number of tools within the toolbox:

• Classification Accuracy
• Dark Object Subtraction
• IMAD Analysis
• PseudoInvariantFactor

The IR-MAD script is based on the below references:

Movement Analysis Tools

Tools for analyzing raw movement data to identify patterns and frequency of activity.

• Visitation By Day Period
