Analysis of Airborne and Satellite Imagery and Map Interpretation and Landforms
For this one, normally we would use atlases of stereogram imagery, and stereogram viewers to get 3D views of landscapes. We cannot do that, as you likely don’t own a stereogram viewer yourself, and I can’t give you one due to Coronavirus restrictions. Thus, we have an alternative in this document.

First, I’ll provide lower-quality images of the stereogram atlases so you can have some reference. Higher-quality scans of these same pages are available on Canvas; please use them. After the images, corresponding 3D-capable Google Maps and Google Earth Web links to those places are provided, so you can use them to get a 3D understanding of the place.

Advice 1: the 3D-capable Google Maps links can be computationally demanding. The Google Earth Web links are computationally demanding. I would recommend only having one or two open at a time.

Advice 2: the stereograms are – to my knowledge – from the later 20th century (1995 at the latest), so they’re a bit old. Things depicted in them may differ somewhat from the modern Google Maps imagery.

Instructions to use 3D-capable Google Maps links:

1. Open the link in your internet browser. Do so by holding down the “Control” key while clicking the link. Alternatively, copy-paste it into your browser’s URL window.

2. There should be a little globe in the bottom-right of the Google Maps window. Click it. Select “enable globe view”, if the option appears.

3. Click the “3D” button that now appears.

4. Congratulations! You should now have an oblique 3D view of the landscape. Use it to answer the questions in the lab that require 3D understanding.

5. However, the questions still refer to the Stereogram Plates, so keep that in mind.

6. If you have any questions, please do not hesitate to ask me.

(For Google Earth Web, things are a bit simpler. Once you open the link, hold left-click to move your viewpoint, while hold middle-mouse to rotate your viewpoint. Scrolling the mousewheel or holding right-click zooms in or out. Click the red-and white compass to reorient to North-top, and click the “2D” button to reorient to a top-down view.)

Document format:

The two images provided for each Plate are in the same format as they’d be in the Stereogram atlas. The first image is a page with some background info on the site, along with some maps or oblique imagery. The second image is the actual stereogram itself. Afterwards is the corresponding Google Maps link.

Note that some parts of the Stereogram images are “doubled”; this is intentional, so as to allow one to use a stereogram viewer on them. In reality, these ‘doubled’ landscape features are not doubled in real life. For instance, in the Plate 27 Stereogram, there are two Mt. Capulins depicted; in reality (as you see in the Google Maps link), there is only one Mt. Capulin.
