![]() Work well across a wide range of applications and devices (web, desktop, and mobile), including desktop applications, such as ArcMap, and older versions of web browsers. ![]() The cached tiles are fast to transmit over the internet and are easily understood by most common mapping software applications, so they are compatible not only with ArcGIS and web apps built with the ArcGIS APIs, but also third-party apps that use OGC protocols such as WMTS. Raster tile layers can also be composed of static operational layers such as thematic maps of your data. Raster tile layers are most appropriate for basemaps that give your maps geographic context such as imagery (as in the World Imagery basemap) or feature-based maps such as in the Topographic, National Geographic, Oceans, and other basemaps. The tiles are statically displayed by the client. These are delivered to client applications as image files (for example, JPG or PNG format) that have been prerendered and stored in ArcGIS Online. Raster tile layerĪ raster tile layer is composed of cached raster tiles, also called map tile caches. Both raster and vector tiles are designed to provide high-performance and high-scalability delivery of map data for visualization purposes. Tile layers can be stored as prerendered raster tiles or as vector tiles. Tile layers come in various formats based on the original source data. The basemaps included with ArcGIS Online are designed for fast and simple access by web maps, web apps, ArcGIS, and nearly any mapping software application. For example, you can include a basemap with tiles of streets in your map to provide a visual reference for the street signs in a feature layer that is also in the map. The basemaps that ArcGIS Online provides are tile layers that give immediate geographic context for your operational layers. Tile layers are useful when you need to expose a map or layer on the web for the visualization of relatively static data.
