Abstract: By storing an increased number of traffic conditions within existing coding uniforms, the system described herein efficiently transmits traffic conditions with a high degree of granularity and low bandwidth cost. A digital map server determines a traffic condition for a portion of a road, packages the traffic condition within a channel of an individual coding uniform of a coding language, and transmits the coding uniform to a computing device. Alternatively, the traffic condition can be encoded within the channel of the coding uniform by the computing device. The coding uniform can also store a length of the portion of road to which the traffic condition corresponds. The computing device may then access the traffic condition, and then render a visual representation of traffic patterns on a digital map. The traffic conditions may also be packaged as arrays within a picture or texture file.

Abstract: Methods and systems of encoding parent-child map tile relationships in a quad tree data structure are provided. A first bit string is generated, wherein the level and position of a node in the tree is transformed into a string containing values of the nodes in a parent-child relationship, in descending order of level, and a second bit string is generated that identifies and disambiguates the specific level in the quad tree of a reference node.
