ABSTRACT
ABSTRACT: Since 2000, the Cartographic Institute of Catalonia (ICC) has been developing its own mobile mapping system within the framework of the GEOVAN project. The GEOVAN project involves the integration in a van of all the sensors needed for acquiring digital stereopairs of images and their direct georeferencing. In this paper all the subsystems of which the GEOVAN is composed are described: the imaging subsystem, which consists of a pair of digital cameras; the orientation subsystem based on GPS/INS integration; the synchronization subsystem; the data storage subsystem; the power subsystem; and finally the control subsystem. Furthermore, a detailed explanation is given of the interaction between the subsystems, operational procedures and calibration of the subsystems. The first steps required for the integration of a terrestrial laser scanner into the vehicle and the direct georeferencing of its data by means of a GPS/INS system are also presented.
