A vector tiled layer references a set of web-accessible vector tiles and a corresponding style that dictates how the tiles will draw. Vector tiles are similar to image tiles, but they store a vector representation of the data instead of a raster representation. Because the data and the visual style are separate, vector tiled layers can be customized to the map, which drives dynamic, interactive cartography. Tile access performance combined with vector drawing means vector tiled layers can adapt to any display resolution, which can vary across devices.
In addition to drawing vector tiled layers, you can also draw vector tiled layers that reference a vector tile package (.vtpk file) on disk. This allows you to draw vector tiled layers offline or preview vector tile packages before publishing a service.
Navigate your map
Vector tiled layers are created at specific map scales with dynamic styling behavior across scale ranges. When vector tiles are used in a map in their native projection, styling is applied dynamically as you zoom in and out across scales. When vector tiles are used in a map in with a different projection than how they are defined, the styling will not be applied dynamically as you zoom across scales. Instead, symbols and text draw precisely for that scale once navigation is completed.
