Minimum zoom level for the tile package. Note: the implementation loads and stores the loaded tiles in batches, each batch has a pre-defined zoom range and it contains all child tiles within the range. The currently used tile batches zoom ranges are: - Global coverage: 0 - 5 - Regional information: 6 - 10 - Local information: 11 - 14 - Streets detail: 15 - 16 Internally, the implementation maps the given tile pack zoom range and geometry to a set of pre-defined batches to load, therefore it is highly recommended to choose the `minZoom` and `maxZoom` values in accordance with the tile batches zoom ranges (see the list above).
