Animated GIF which shows two renderings of an digital elevation model (DTM) with 1 Hz frequency. One DTM provides better resolution than the other. The image shows a river or a series of water bodies with a distinct, winding path. The river is highlighted in a darker color, possibly brown or orange, which contrasts with the lighter, more uniform tones of the surrounding land. The surrounding area has a textured appearance, suggesting it might be a forested or mountainous region. The overall image has a high level of detail, allowing for the observation of the river's course and the surrounding terrain.
