This paper describes the assesment procedure applied to a system for automated geocoding of digital aerial imagery. The image analysis part of the system is an image-map-registration, which has to improve a preresigistration provided by the sensor model and the navigation parameters. The performance and the costs of the system components are discussed in relation to an interactive solution and to the use of vary accurate navigation systems, which are expected to be not available under certain cost constraints. Performance measures for realiability and accurarcy are defined in the context of an assestment function. The evaluation methods are applied to an example geocoding algorithm. As the emphasis of the paper lies on the assement procedure, the results have only illustrative character.
