Great American Eclipse 2024, part II - USA - Texas & Oklahoma
The 2nd part of the complex animation shows the path of the April 8, 2024, total solar eclipse known as the 2024 Great American Eclipse. It includes 4 major views: the top with Google Hybrid overlay (325-330 km altitude), the shadow in & out (50km altitude), and local views (mountain peaks or city views from 3-5km to 20km altitude).
Various graphic techniques have been applied through this presentation, including Google Hybrid overlay and Google Earth atmosphere mode (mountain view).
The movie is concentrated on the southern part of the USA, where the umbra flies above one of the biggest urban areas in the region (Dallas - Fort-Worth metroplex) as well as interesting from the tectonic point of view - Ouachita Mountains.
The video displays briefly shadow movement above the biggest cities in Texas: San Antonio, Austin, Killeen, Waco, Dallas-fort-Worth, Tyler, and Texarkana in the spans of 10-30 seconds depending on the local circumstances (mostly 10 seconds).
Southern Texas will experience the greatest eclipse with a 4m27s duration near the Eagle Pass border town. The Moon's shadow has been encircled by a 5km grazing zone area, which corresponds to the smallest Baily's Beads appearance, just before and after the totality.
This GIS-based video has been made with the eclipse data based both on NASA.gsfc.eclipse service and Xavier Jubier eclipse page, from where I picked up the most important calculations. I also used the Eclipse24.org webpage in order to grab the local area boundaries and Peakfinder.org to identify local mountain panoramas.

I would advise you to get prepared for several optical phenomena possible to spot around the time of totality.
