Abstract
A graphics or image rendering system, such as a map image rendering system, may receive map data associated with a set of zoom levels, where the map data includes style attribute data corresponding to various features of a map surface at corresponding zoom levels. The system may interpolate at least some of the style parameter values from the received map data to provide style parameter values over a range of zoom levels.
