The video has one frame per year. Each frame is a 1.7-terapixel snapshot of the entire Earth, generated from 30-meter resolution Landsat images. Landsat collects new imagery over each location in the world about once every two weeks. Using Earth Engine’s analysis platform, each year’s worth of images was combined into a single cloud-free, per-pixel composite for that year.
This scene also comes from the Ucayali River and it is a nice example of how both neck cutoffs and chute cutoffs form. First a neck cutoff takes place that affects the tight bend in the right side of the image; this is followed by a chute cutoff immediately downstream of the neck cutoff location, as the new course of the river happens to align well with a pre-existing chute channel. The third bend in the upper left corner shows some well-developed counter-point-bar deposits.
