Among all the fields of application of digital elevation model (DEM) data it seems rational to highlight the field of comparison between real-life collected data and the model to be able to produce the new, previously non-existent information and conclusions.
The great contribution was made by the NASA's Shuttle Radar Topography Mission (SRTM) giving the public access to highly detailed geospatial data of the whole surface of our planet.
With rapid development of digital cartography and GIS (geography information systems) a lot of related techniques and approaches aiming at usage of spatial data emerged. The details on estimating these distances and the results of accuracy evaluation and error measurements are provided.ģD panorama rendering GPU rendering GPU z-buffer estimation of distances up to objects of relief digital elevation model geo-information systems. Given geographic coordinates as input this method generates a panorama image and also a distance map with a distance from the point of view to every pixel of the rendered panorama. This work presents a method of rendering of360° panoramas based on real-world DEM (Digital Elevation Model) data using graphic processor (GPU).
