Vector maps
The vector tiles maps API consists of two main parts: pre-defined vector data pieces (tiles) and a style which is defined by a text file. Usually, only a style file is necessary, containing information also about other components. Three vector maps layers are available: base map, points of interest, and a layer of labels and lines (place names, addresses, street names, street and boundary lines, etc.), which is suitable as an additional layer to an orthophoto map or satellite imagagery. Layers can be combined or used separetely.
