Abstract: To generate a description of a raster map image that includes a representation of a body of water having a color gradient that appears constant in response to a zoom operation, a description of geometry of the body of water is generated for a selected geographic area. Using a raster representation of the body of water having a color gradient, at least two blur raster images are generated: a first blur raster image is generated using a first blur radius, and a second blur raster image is generated using a second blur radius different from the first blur radius. The description of the geometry of the body of water, the first blur raster image, and the second blur raster image are provided to a client device for generating raster map images of the selected geographic area.

Abstract: Systems and methods for applying one or more route-based modifications to a map are provided. In some aspects, a system includes a pathfinder module configured to determine a primary route from a beginning point to a destination point on the map. The pathfinder module is further configured to generate one or more primary modifications to the map based on the primary route. The system also includes a restyling module configured to apply the primary route and the one or more primary modifications to the map. The one or more primary modifications include at least one of a) adding a first object to the map that would otherwise be excluded from the map if the primary route is not applied to the map and b) excluding a second object from the map that would otherwise be added to the map if the primary route is not applied to the map.
