“Imagery Base Map” offers a good overview of the current landscape thanks to a combination of orthoimages (rectified aerial photographs) and cartographic elements. It is based on official data: the topographic landscape model, the digital elevation model, the digital cartographic models and the official index of roads. The content varies depending on the zoom level. The vector representation is based on the Maplibre Style Specification. The data basis consists of vector tiles (Base Vector Tileset). The orthoimages (SWISSIMAGE) are displayed as raster tiles.
