City example: Vector Map - 15 MB, Online 15th Zoom - 50 MB, 16th - 200 MB, 17th - 800 MB. Significantly bigger comparing to Vector maps.The data could be updated after expiration like traffic tiles are updated every 20-30 minutes (configurable).Basically, each website with maps could be used as a source data. Indefinite variety of external web-sources.
create offline cache and be able to download missing tiles on the fly. Possibility to preload data partially i.e.Raster maps could be loaded on the fly during map browse.Display time is reasonably faster because maps are not rendered by the device.They often look pixelated because each pixel has its own value or class. Raster map tiles are usually regularly-spaced and square. In contrast to vector maps which consists of binary data like roads, points, polygons. Raster data is made up of pixels (also referred to as grid cells) - set of small images (tiles). Note: You can also change the main source of the map from vector maps to online tiles. Online OpenStreetMap tiles for OSM editing purposes.Active cycling / running trails as overlay.Rich topographic maps with hillshades / slopes.There is a big variety of possible use cases cause they vary on infinite external map source possibilities. You can also switch default maps to online web raster tiles. You can display an overlay of hiking routes, live rain maps, live traffic data and an underlay of satellite imagery mixing with semi-transparent base vector map. For example, useful Hillshade / Slope information could be displayed as a raster layer. Raster maps allow to combine different map sources with Vector Maps. Raster maps is an extensive addition to the offline OpenStreetMap Vector maps the application uses by default.
