This is a map of LiDAR Imagery that has been converted to a raster image. I changed the symbology a few different times to see what would best differentiate the features. I also checked the image against aerial imagery to make sure I had the road in the correct place. I used imagery provided by ESRI on the online resource center.

Click the "ArcMap" link next to "View Service In:". This will let you download a .lyr file that you can use in an .mxd to "link" to aerial imagery for the world (you must be connected to the Internet). I believe they update it twice a year so it is fairly current.
