vector tile style
A vector tile style is a JSON structure and accompanying resources that define how the contents of vector tiles are displayed in a client application. It contains sets of visual properties for each layer, such as fill colors, viewing levels, and labels, and its resources include fonts and sprites. It is typically created using the Vector Tile Style Editor and stored as an item in ArcGIS Online. ArcGIS Runtime APIs can download a vector tile style as an item resource cache to display tiles from a vector tile package (VTPK) in offline applications.
