: The CHANGE generalization software package developed by the University of Hanover was applied to Turkish topographic base map data. The package is capable of processing roads and buildings. Through support programs, several benefits were gained, including a reliable data conversion between the internal file format of the package and DXF, improved geometric quality of the building data before generalization, and statistical evaluation of generalization results. Because the package runs in batch mode, the ACAD MAP CAD and GIS software package was used as a graphic interface, which has more functionality than a simple interface in this study. The paper introduces a generalization approach which can be implemented in a practical setting. An overview of the results of the case study shows the evident applicability of this approach.
