Generating Map Elements in ArcMap

In this exercise, previously prepared layers including political boundaries, roads, georeferenced imagery and standard map elements are formatted for effective map layouts. The overlaying of different pieces of information provides a visualization of spatial relationships between the layers and is one of the most important advantages of GIS.
