Before beginning this tutorial, there was only one aerial file: aerial.jpg. During the tutorial, you generated the two additional files. The JGWX file contains the spatial referencing information that you just created. Because this new file has been created, the image will now line up spatially whenever you add it into a new data frame. In other words, you only need to georeference a layer once. The XML file contains the metadata used by ArcCatalog to describe the newly georeferenced aerial image. If you were to delete these two accessory files, the image would no longer be georeferenced and would be returned to its original state.

Digital Sanborn Maps

Fondren Library provides access to Digital Sanborn Maps for Texas. This database can be accessed here: Digital Sanborn Maps (Texas). Founded in 1867 by D. A. Sanborn, the Sanborn Map Company was the primary American publisher of fire insurance maps for nearly 100 years. The maps provide a wealth of information, such as building outline, size and shape. Come explore America's rich and diverse building history. For this tutorial, you will practice what you learned above by georeferencing two Sanborn maps of Rice University from 1925 and 1951.
