Aspect identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors. This tool creates an aspect map from an elevation data source. The results define the areas that can be seen from the observer locations. The input point locations can represent either observers (such as people on the ground or lookouts in a fire tower), or observed objects (such as wind turbines, water towers, vehicles, or other people). This tool identifies the areas an observer can see, accounting for surface topography. The output of this tool is a hosted imagery layer. Slope represents the rate of change of elevation for each digital elevation model (DEM) cell. This tool creates a surface that shows the slope of the input elevation data. The raster analysis tools can be used in Map Viewer, in ArcGIS Python API, ArcGIS REST API, and ArcGIS Pro.

Finding suitable locations to build solar power plants, using statewide elevation and land cover data.Computing vegetation coverage surface from multiple band imagery, so you can make an agricultural assessment.The following are two examples of performing raster analysis: With the ArcGIS Enterprise portal, you can use built-in raster analysis tools to process and create new persisted layers, which can be made available as image and feature web layers. Raster analysis provides scalable distributed processing for large image and raster collections, including your existing GIS and imagery data.
RASTER IMAGE TOOLS ARCHIVE
It can also be applied to massive collections of imagery, such as the current Landsat 8 archive or the growing Sentinel-2 archive. ArcGIS Image Server distributed analytics can work with a single large raster dataset, such as world elevation, or a high resolution satellite image.
