Georeferencing is the process of taking map images in formats like png, tiff or jpegs and correctly locating them in a map document. This tutorial takes you through the steps involved in both ArcMap and ArcGIS Pro.

Color Scan is an extension to ArcMap that has tools to create GIS layers from georeferenced map images. Download a 30 day free trial here: https://www.spatialmonkey.com/trial/
