Studies and Analysis of Acquisition Methods and Processing Technology of Information Obtained by IMU/LIDAR/Soundings

Geographic information represents, within the European Policy for Geographic Information a complex part of information society which changes continously and which has a wide range of applicability. This can be groupped into two categories: spatial, geographic information and descriptive, qualitative information. These two types of data can be integrated within the same information management system by creating a Geographic Informational System. The terrestrial surface can be represented starting from a series of measurements to determine the position of characteristic points after which these points shall be projected on a plane surface depending on how large the surface is. The position of these points is determined from other points the position of which is well known. These points form a an infrastructure which is called geodezic network. The multitude of georeferentiate points form an image defining the structure of a map. In order to realize this map with the highest degree of accuracy and veracity, the immages aquired through various aquisition methodes are subject to more sophisticated techniques for modelling and processing.
