PRINCIPLES FOR A NEW EDITION OF THE DIGITAL ELEVATION MODELING SYSTEM SCOP

摘要

OEMs as information (sub)systems storing vectors, raster, image pixels, and attributes. Communicating with other databases, and accessing DEM informatlon, via (TOP)SQL. Treating topology in terms of relationality; dealing with true three-dimensionality. Main functions. Combining vectorial algoritms with those of raster geometry. Patchwise processes With stages varying locally. Controlling DEM processing via object oriented programming in a multitasking, and eventually distributed system. Machine Independent base modules. Modes for real-time processing, sub-system (slave or driver) mode, batch processing mode. Employing parallel programming including massive parallelity.
