摘要：Vectorial data acquisition for Geographic Information Systems(GIS) is a real bottleneck which is to be overcomed bya combination of results of surveying, photogrammetry, andmap data digitization. The homogenization problem consistsof consistency checks in first part with the more accuratedata set, therefore math models must be developed to decideon data acceptance and rejection respectively.The paper introduces with overall accuracy measures forthe three data acquisition methods. Its main part solves themathematical problem when all three data sources are joinedtogether. The corresponding linear models and hypothesistests are shown. It concludes with pros and cons if differentobjective functions (Lb L2 , Loo) are used for parameter estimation.
