Appl. No.:

13/306052

Inventors:

Brian Cornell - Kenmore WA, US
Sean Egan - Seattle WA, US

Assignee:

Google Inc. - Mountain View CA

International Classification:

G09G 5/00
G09G 5/02
G06T 15/40

US Classification:

345629, 345421, 345422, 345592

Abstract:

A digital image rendering system, such as a geographic map rendering system, receives image data from an image database, such as a map database, in the form of data having image features defined as sets of image objects arranged in a series of layers. The image rendering system processes the received data in a manner that allows for rendering the original layered data without rendering each original layer separately by reordering the original layered digital image data into fewer layers.

International Classification:

G09G 5/00

US Classification:

345629

Abstract:

A map server generates vector descriptors in a non-raster format, each indicating a geometry of a respective map element, to render a first map image of a selected geographic region at a client device. The map server then provides the vector descriptors to the client device. Upon receiving an indication that a second map image for the selected geographic region is to be rendered at the client device, the map server generates a modification indication that indicates a set of one or more vector descriptors, each of which corresponds to a respective map element that is rendered in one but not both of the first map image and the second map image, and provides the modification indication to the client device, so that the client device can render the second map image using at least some of the vector descriptors and the modification indication.

International Classification:

G06F 3/0484
H04L 29/08

US Classification:

715800

Abstract:

First map data is generated in a vector format for displaying a first map image at a client device. The first map image corresponds to a perspective of a camera panned to a certain location at a certain zoom level. The first map data is provided to the client device via a communication network. Modification data is generated at a map server in a vector format, the modification data specifying a difference between the first map data and a second map data, where the second map data is for displaying a second map image corresponding to the same perspective of the camera panned to the same location at the same zoom level. The modification data is provided to the client device via the communication network for generating the second map image using the first map data and the modification data.

US Classification:

345619

Abstract:

A computing device receives, via a communication network, map data including (i) a description of geometries of map features and (ii) a first description of visual characteristics defined separately and independently of the description of the geometries. The computing device applies the visual characteristics to the geometries to render a first digital map. The computing device then receives, via the communication network, a second description of visual characteristics for application to the geometries previously provided to the computing device as part of the map data, and applies the second visual characteristics to the previously received geometries of the plurality of map features to render a second digital map.
