PRo3D - a tool for remote exploration and visual analysis of multi-resolution planetary terrains

This paper describes a viewer called PRo3D that enables planetary scientists to explore and analyze accurate reconstructions of planetary terrains. These reconstructions, derived from 3D-processing of images obtained by rovers, landers, and satellites, provide access to the corresponding planetary surfaces on Earth in a virtual space. PRo3D allows zooming through a broad range of geometric scales to study geologic structures from far away to microscopic close-up. The viewer provides various measurement tools to derive the true dimension of surface features and let scientists place annotations in 3D space. PRo3D is a component of the FP7-PRoViDE tool set.
