Filed:

Sep 26, 2008

Appl. No.:

12/285002

Inventors:

Neil Turner - Emeryville CA, US
Christian Fernandez - El Cerrito CA, US
Michael Lessin - San Leandro CA, US

International Classification:

G06F 17/30

US Classification:

707 10, 707E17044, 707E17032

Abstract:

An image tile server importantly includes an image tile cache, to support a tiled map display in a user device. Instead of the conventional user device client (e.g., an Ajax client) making image requests directly to a mapping server (MS), a display device initiates an image request of a tile server (TS), and the tile server returns the requested image. However, importantly, the tile server (TS) also retains a cached copy of the returned image for faster retrieval at a later time relating to another image request by the same or different user device.
