1. Click Imagery.zip above to download the tutorial data.
2. Open the Downloads folder.
3. Right-click Imagery.zip and select Extract All....
4. In the 'Extract Compressed (Zipped) Folders' window, accept the default location into the Downloads folder and click Extract.
5. Drag the unzipped GeoprocessingImagery folder onto your Desktop.
6. Close all windows.

1. On the Desktop, double-click the Imagery folder.
2. Double-click the Imagery.aprx project file to open the project in ArcGIS Pro.

Before you can georeference an image, you must have existing GIS data with known coordinates containing similar features to those in the image. While you can georeference to the built in basemaps, additional vector data can be helpful, because vector data can lay on top of the imagery you are trying to georeference, so they can be seen simultaneously, whereas relying on the basemap would require repeatedly toggling the image on and off or adding a transparency to the image, so that both the image and the basemap are visible, but this type of display can be more difficult to interpret. Since you will be georeferencing an aerial image of the Rice campus, have vector layers related to campus features would be helpful.

1. In the Catalog pane on the right, expand the Databases folder.
2. Expand the Imagery.gdb geodatabase.
3. Click the first buildings feature class to select it.
4. Hold down Shift and click the last streets feature class to select all four feature classes in within the geodatabase.
5. Right-click the streets feature class and select Add To New Map.

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.

Image Added

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.

1. In the Catalog pane, expand the Folders folder.
2. Expand the Imagery folder.
3. Right-click the aerial.jpg raster image and select Add to Current Map.

If the Add to Current Map command does not work, you can click the Add Data button within the Map tab on the ribbon and then browse to and select the same image.

1. In the Table of Contents, right-click the streets layer and select Zoom to Layer.
2. In the Table of Contents, right-click the aerial layer and select Zoom to Layer.

Both layers appear in the data frame, but, as expected, the image cannot be lined up with the other data layers, because it has not been georeferenced and no projection has been defined.
