Raster analysis can identify trends and patterns in data or detect changes over time on a cell-by-cell basis. Overall, raster analysis is a helpful tool in GIS for analyzing large volumes of data quickly.

A common use of image data in a GIS is as a background display for other feature layers. For example, orthoimages displayed underneath other GIS layers provide the map user with confidence that map layers are spatially aligned and represent real objects, as well as additional information. Three...

Environment settings, such as Processing extent, are not reflected in the feature count. Analysis settings The Analysis settings group includes the following parameters: Value field is used to assign values to the output raster. It determines the type of output raster. If the field is integer, ...
