To verify if your GIS has raster analysis capability, use the arcgis.raster.analytics.is_supported(gis) method. There are many ways to clip out a part of an image or raster in ArcGIS. What you choose may depend on what you’re doing. For example, if you’re using ArcMap and have a graphic, you can use the Clip button on the Image Analysis window. Raster data can be images (raster images) with each pixel containing a color value.

When working with imaged raster data, there are four types of resolution you might be concerned with: spatial resolution, spectral resolution, temporal resolution, and radiometric resolution. In a GIS, you are most often concerned with the spatial resolution of a raster dataset, especially when displaying or comparing raster data with other data types, such as vector.
