Ensure that all four feature classes (streets, sidewalks, parking, buildings) appear in the Contents pane on the left. If you are missing any layers, drag them from the Catalog pane on the right directly into the Map view. The layers of the Rice campus should look familiar. If desired, update the symbology of each of the layers to a color of your choice by right-clicking on the color patch beneath each layer name and selecting a color. For example, you might choose to make the parking and streets layers two shades of gray, the sidewalks layer tan, and the buildings layer red.
Now you will add in a JPEG file depicting an aerial view of campus. This image is just like any other image file you are familiar with and does not contain any sort of spatial reference.

- Right-click the aerial.jpg raster image and select Add to Current Map.
