Scanned images of early maps and aerial photography often provide an ideal historical backdrop upon which to overlaying contemporary geospatial data. You will be amazed at how georeferenced maps can be used to identify changes in both the physical and cultural landscape. In this class, we will introduce georeferencing and walk through the steps and decisions one makes throughout the process. You will also learn how to upload and share your final georeferenced maps to ArcGIS Online.
This is a hands-on session where you will make use of the library’s extensive collection of local scanned map images. We’ll also bring in authoritative GIS data layers from Baltimore City and our Maryland State government. There is no prerequisite for this class. Some knowledge of GIS may prove useful. <Register here>
