Creation of an urban model for in-city positioning using laser-scanning

Abstract

The investigations are based on the evaluation and the analyzes of high accuracy LIDAR images taken over Lithuanian cities, thereby taking into account the geodetic control measurements and foreign expert experience. The progressive aerial laser scanning approach with combination of digital photogrammetry technology, – a GPS-IMU system and a digital aerial photography have been used for the creation the urban spatial model. The application feasibility is investigated. A description of equipment, technological features and application possibilities is presented.
