Abstract
Digital spatial data are subject to temporal changes. The common approach to verify and update the data is to superimpose the data with up-to-date orthophotos and check the correctness interactively. This is a very time consuming and expensive process. We propose a method for the automatic quality surveillance of GIS data, in particular in respect to changes of settlement and industrial areas. These classes correspond to the classes defined for the German ATKIS® geodata. In this paper the up-to-dateness of ATKIS is checked by use of a high resolution color aerial image of a scene near Hannover. The analysis uses the knowledge-based system GEOAIDA, which allows an intelligent, clearly structured, and flexible control of a scene interpretation by utilizing a semantic scene description. GEOAIDA is extended to use a state transition graph that models possible expected temporal transitions in the scene. The system produces a hierarchic, pictorial description of the results while the structural context of the identified objects including the associated attributes is preserved in a graph. The results of a quality surveillance procedure in the examined GIS data are illustrated.
