An overview of the Change Detection toolset

Disponible avec une licence Image Analyst.

The Change Detection toolset contains tools that perform change detection between raster datasets.

Additional time-series change detection capabilities are available in the Multidimensional Analysis toolset.

Tools in the Change Detection toolset

Tool	Description
Analyze Changes Using CCDC	Evaluates changes in pixel values over time using the Continuous Change Detection and Classification (CCDC) method and generates a change analysis raster containing the model results.
Analyze Changes Using LandTrendr	Evaluates changes in pixel values over time using the Landsat-based detection of trends in disturbance and recovery (LandTrendr) method and generates a change analysis raster containing the model results.
Compute Change Raster	Calculates the absolute, relative, or categorical difference between two raster datasets.
Detect Change Using Change Analysis Raster	Generates a raster containing pixel change information using the output change analysis raster from the Analyze Changes Using CCDC tool or the Analyze Changes Using LandTrendr tool.
