This unit includes relevant issues related to vector data models, feature based modelling, applications. Besides imagery data the majority of GI data available is feature based and founded on vector geometry. Topology modeling also is very common nowadays, as many analysis like routing or neighborhood analysis require it. Spaghetti modelling becomes more and more and exception. In every country there are important feature and vector geometry based application models available e.g. in Topography / Cartography. In Europe every GI course should include some information on INSPIRE. As in different application domains different data models are used, sometimes for the same feature types, integration and transformation of models are an important issue also.
