The erection of a summit cross, a cairn, a surveying sign, or the naming of a mountain does not necessarily make any point a summit. However, to evaluate their orographic significance, they can be classified according to height, dominance, and relative prominence. These three parameters are measurable and thus objective and uniform, easy to specify, and seamlessly applicable to the entire Earth, from eight-thousanders to coastal hills. In printed maps such as the Topographic Map of Germany, the Austrian Map 1:50,000, and especially the Swiss National Map, mountains and peaks were also differentiated according to their significance. Unfortunately, today's digital successors almost entirely dispense with this. The application of the classification procedure for labeling mountains and peaks in the City Map of the Regionalverband FrankfurtRheinMain is demonstrated. In addition, exemplary examples from various regions are provided.
