Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for rendering vector graphics as multiple tiles in an interactive mapping system. In one aspect, a method includes receiving map data in an interactive mapping system. A set of one or more vertices is that defines a vector graphic is processed, where each vertex defines a map location corresponding to map coordinates. For one or more portions of a vector graphic that coincide with a user viewport, one or more respective vector tiles is generated, where the user viewport defines a first region in which map coordinates can be displayed. On a user command, one or more new vector tiles is rendered at the client device using vertices that coincide with the user viewport at a second region, where the respective new portions did not previously coincide with the user viewport at the first region.
