Abstract: Two-dimensional (2D) edge-based map matching includes using a 2D edge-based map matching platform. The 2D edge-based map matching platform receives at least one request to match a probe data point to one of a plurality of thoroughfare segments. Next, the 2D edge-based map matching platform determines respective edges of the plurality of thoroughfare segments and causes a matching of the probe data point to the one thoroughfare segment based on a comparison of the probe data point to the respective edges of the plurality of thoroughfare segments.

Abstract: An approach is provided for providing a unified extensible platform for overall probe data and storage. The approach comprises causing, at least in part, a storage of probe data in one or more information spaces, one or more namespaces of the one or more information spaces, or a combination thereof. The approach further comprises determining one or more nodes for processing the probe data based, at least in part, on one or more context criteria, the one or more nodes associated with the one or more information spaces. The approach also comprises determining to provide access to the processed probe data via the one or more information spaces, the one or more namespaces, or a combination thereof.

Abstract: A system and method for providing geographic data to end users' computing platforms. A server maintains downloadable geographic data that are organized into pre-computed parcels that correspond to pre-determined sub-areas into which the entire geographic region serviced by the server is divided. The server responds to requests from the end users' computing platforms for navigation services and data by sending selected pre-computed parcels of geographic data to the end users' computing platforms. The end users' computing platforms store the pre-computed parcels received from the server in a cache memory. The end users' computing platforms use the data in the pre-computed parcels to provide navigation-related features locally.

Abstract: A method and system for managing memory resources in a system used in conjunction with a navigation application program that accesses geographic data. The geographic data are comprised of a plurality of data records. The plurality of data records are organized into parcels, each of which contains a portion of the plurality of data records, such that the data records in each portion of the plurality of data records that forms each parcel are accessed together. One or more buffers each that forms a contiguous portion of the memory of the navigation system is provided as a cache to store a plurality of parcels. One or more data structures located outside the contiguous portion of memory identify the parcels of data stored in the cache and the locations in the cache at which the parcels are stored. The one or more data structures located outside the contiguous portion of memory in which the parcels are cached are used to manage the parcel cache to use it efficiently.
