Overhead
Overhead Imagery is the default imagery you get whenever you open a Profile. You can validate you're viewing the Overhead imagery by checking which icon is selected in the timeline located at the top of the page
Oblique Imagery
Oblique imagery is the 2nd option from the left, located in the Timeline.
When you click on Obliques, we will take you to the most recent set of oblique images. The timeline entries also shift to show only dates with oblique imagery.
Google Maps
Google Maps is the 5th option in the Imagery Timeline.
You will then be able to access Google Maps by clicking on "Google". You can also access Street View or MLS Photos, if they're available, from that same Timeline.
