Accuracy requirements of fractions of a millimeter for thepositioning of beam-guiding magnets in synchrotons, monitor-ing of speedy sub-seatunnelling with lengths exceeding 25km, the construction of extremely long bridges of suspensionor "cast-and push"-type, but also geometrical industrialquality control and robot calibration in real time, and eventhe analysis of prestressed cable nets, are few examples ofthechallenging new tasks demanding responses from themodern engineering-geodesist.In this volume, a general view of Engineering Geologyispresented, its state of the art and up-to-date informationabout recent scientific tasks, aims and methods. Thecontributions focus on Theoretical Aspects, Techniques ofMeasurements, Techniques of Data Processing and Computing,Reports About Selected Executed Projects, Special Tasks,e.g. Realtime Positioning and Navigation, IndustrialManagements,Image Processing. But also the role of geo-desists in collaboration with civil and mechanicalengineers, technical designers and architects is outlined.As a reference book, this volume will be useful forresearchers, students and practitioners in EngineeringGeodesy and neighbouring disciplines.
