Creating maps composed of polygons and polylines within a Geographic Information System (GIS) software, such as ArcGIS, is a common task for many GIS professionals across multiple disciplines. The
development of these types of maps can be a complex and labor intensive process. This is especially true when creating geologic maps, which represent a complex network of geologic units, faults, joints, and other features, often with cross-cutting relationships. Those who have tried to create a map like this probably realized, early in the process, that it is not as straight-forward as they imagined due to the many different work-flow patterns that exist for creating maps in a GIS. In this presentation, we will discuss common problems and how to manage them, as well as give suggestions that will make your next geologic mapping project more streamlined and organized.
