Specify the name and location for the output raster.In the Raster Calculator window, double-click one of the rasters to be analysed, click the minus sign ( -), and double-click the second raster.In ArcMap, navigate to ArcToolbox > Spatial Analyst Tools > Map Algebra > Raster Calculator.Option C describes the steps to find the raster value differences using the Difference tool from the Image Analysis window, which does not require an extension. Option A describes the workflow when using the Raster Calculator tool from the Map Algebra toolset, whereas Option B describes the workflow when using the Minus tool from the Math toolset. The instructions provided describe the steps to find raster value differences between two rasters. ArcGIS Pro is completely integrated with ArcGIS Online making it easier for users to share, view, edit and access data and maps for a project with colleagues and stakeholders. The Raster Calculator and Minus tools require a Spatial Analyst license. Alternatively, environments without the ArcGIS Spatial Analyst extension can use the Difference function from the Image Analysis window. In ArcGIS Desktop, these tools are located in the Spatial Analyst toolbox. Spatial analysis tools such as the Raster Calculator and Minus tools can provide powerful insights on raster value differences between raster images that are geographically overlapping.
