Agglomerations: generalized boundaries
This API provides generalized administrative boundary data for Switzerland and the Principality of Liechtenstein, specifically simplified representations of agglomerations suited to thematic maps and small-scale cartography. The generalized boundaries are derived from the more detailed digital boundaries maintained by the Federal Office of Topography, reducing complexity while preserving spatial accuracy for broader visualizations. The dataset is published and updated annually by the Swiss Federal Statistical Office (Bundesamt für Statistik, BFS) as part of Switzerland's national statistical and geospatial infrastructure. It is intended for use in cartographic production, regional analysis, and statistical reporting where detailed boundary data would be unnecessarily complex or visually cluttered at smaller map scales.Administrative borders which have a low level of detail are often needed for thematic maps and representations on a small scale. The digital boundaries of Switzerland and the Principality of Liechtenstein, which are updated annually by the Federal Office of Topography, are often too detailed for th…
