Samenvatting
In Part III of the SIGMO study data inputs and modelling results are dealt with. Data sources, the survey, the level of service data and the land use data are discussed. As the various data sources include different zonal subdivisions and, moreover, calibration and validation are carried out for different geographical aggregation, an integration of zonal systems is presented. For abstracts of the other parts see B 15351, 15352, 15354, 15355.
