This lesson explains how to control layer visibility – including fading them in and out of the display – when you author animations in ArcGIS Pro. Layer visibility can be a crucial element in the geographic story you want to tell in your video. For example, you might want your video to show the ‘before’ and ‘after’ maps for a neighborhood if a proposed highway is approved, or reveal hidden content such as the rooms, elevator shafts and staircases within a building. In our example, we’ll be visually lining up a geolocated Japanese painting by Hokusai (circa 1829) with the virtual world to validate its estimated physical location. In this short video, you will learn how to: • Capture layer visibility within a keyframe • Preview your animation via playback • Capture layer transparency within a keyframe • Update an existing keyframe with new properties After watching this lesson, you might be interested in other lessons in the series that cover animation techniques in more detail.
