Use Imagery Viewer to visualize and explore imagery through time and space. This app includes tools for navigating through time, recording locations, measurement, and more. A single-image configuration allows users to focus on one imagery layer and a two-image configuration allows users to compare two imagery layers using a swipe tool.
