05: Turning Imagery into Information | The ArcGIS Imagery Book

Image analysis allows us to derive new understanding from existing data by creating analytic maps for insight and knowledge. These raster (cell-based) layers can be used to map and model virtually anything that happens across the earth’s surface, like agriculture, planning, hydrology, climate, wildlife habitats, and much more. The big idea in this chapter is that imagery data—with its cell-based data structure—allows for the systematic and controlled analysis of a vast array of phenomena across multiple layers.
