Based on a comparison of a three-dimensional terrain on the respective tile with at least one pre-defined tile pattern, either an identifier (19) for a pre-defined tile pattern or data describing the terrain on the respective tile are stored in the entry. A method of determining height coordinates using the database (10) and a navigation device including the database (10) are also provided.",
