Geographic visualizations are, due to the limited need for vertical navigation,  suitable for touch tables. In this poster we consider the design of interaction design for selection and manipulation through touch on the screen used for the display of 3D geographic visualization---in our case the visualization of and interaction with drone traffic over rural and urban areas---focusing on moving from a monoscopic to a more immersive, stereoscopic touch table, and how this move affects the interaction design. With a monoscopic display our stereoscopic vision uses the graphics to perceive the location of the surface, and touch interaction can naturally and intuitively be performed on top of 3D objects. Moving to stereocopic display, for increased sense of immersion, the graphics no longer provide visual cues about the location of the screen. We argue that this motivates modification of the design principles, with an alternative interaction design as a result.
