| Abstract | This paper presents a methodology for visualizing, analyzing and editing digital elevation models through the use of a virtual reality interface that offers a three-dimensional view of the data, and a set of interaction tools. These tools allow experienced remote sensing data users to manipulate the information in an intuitive and realistic way. An API offering analysis functions commonly used during the manipulation of such kind of data is implemented and assessed. An editing component has been created to modify the data being visualized, and some techniques, including Taubin's l smoothing algorithm, are described in detail. Once generated, digital elevation models frequently present errors due to problems that occurred during the imaging process or raw data processing. These errors need to be removed as efficiently as possible in order to produce a reliable product. This is currently achieved by making a difficult and subjective analysis of the model through a two-dimensional interface and using line command based instructions. A software prototype, called DEMEditor, has already been developed and used to validate the newly adopted methodology. |
