Abstract: Methods described herein relate to offline term searching. The method includes receiving one or more characters of a search query. The method also includes generating one or more search indicator values based on the one or more characters of a search query. Each search indicator value of the one or more search indicator values includes a digest of the one or more characters of a search query inputted into a minhash function with a distinct salt value input. The method further includes comparing the one or more search indicator values with one or more sets of database indicator values. Each database indicator value in the one or more sets of database indicator values corresponds to a database value. Corresponding apparatuses and computer program products are also provided.

Abstract: Provided herein is a method of generating and communicating map version agnostic road identifiers. Methods may include: providing an indication of a route request between an origin and a destination; receiving a list of road link identifiers in response to the route request; in response to the first road link identifier not corresponding to a road link identifier of a network of road link identifiers: applying an XOR function to the first road link identifier and a subsequent road link identifier in the list of road link identifiers; in response to a result of the XOR function applied to the first road link identifier and the subsequent identifier corresponding with a road link identifier of the network of road link identifiers, adding the road link identifier of the network of road link identifiers to the route.

Abstract: An approach is provided for providing routing calculations and route guidance based on geographic positioning and/or other sensor data from one or more mobile devices independent of map data. A routing platform processes and/or facilitates a processing of one or more probe data samples associated with at least one mobile device to determine one or more device tracks. The routing platform processes and/or facilitates a processing of the one or more device tracks to determine at least one tessellation, wherein the at least one tessellation is a subdivision of a plane or sphere into one or more tiles and a plurality of segments. The routing platform further determines one or more relationships between one or more of the plurality of segments based, at least in part, on a mapping of the one or more device tracks against the at least one tessellation.

Abstract: Provided herein is a method of estimating a travel time along a route. Methods may include: obtaining a route between an origin and a destination, where the route includes a plurality of road links; identifying a subset of road links of the plurality of road links; providing an identification of each road link of the subset of road links to a service provider; receiving an indication of a pace of travel along each of the subset of road links; computing an estimated travel time along the route based on the pace of travel along each of the subset of road links; and providing an estimated time-of-arrival at the destination based on an identified departure time and the estimated travel time along the route. Methods may include computing an estimated travel time error along the route, and providing the estimated travel time error as a potential error of the estimated time-of-arrival.

Abstract: An approach is provided for representing an aerial route in a three-dimensional (3D) space. The approach, for example, involves determining a root 3D shape encompassing an aerial route through a 3D space. The 3D space is partitioned into a hierarchy of 3D shapes, and the aerial route comprises a list of 3D shape identifiers (IDs) corresponding to the 3D shapes that form the aerial route. The approach also involves recursively comparing a respective 3D shape ID of the root 3D shape or child shapes of the root 3D shape to the list of 3D shape IDs of the aerial route. The approach further involves generating a traversal command list by selectively adding the respective 3D shape ID that matches a 3D shape ID of the aerial route or includes the 3D shape ID as a child 3D shape ID. The approach further involves providing the traversal command list as an output.

Abstract: A method, an apparatus, and a computer program product may be provided for requesting traffic data. The apparatus may determine at least one map area comprising road segments, said map area having at least one map area identifier, determine road segment identifiers for the road segments of the at least one map area, send to a data service, a request for traffic data, said request identifying the map area, and receive from the data service, a bloom filter set, the bloom filter set comprising a plurality of bloom filters, said bloom filters in the set corresponding to traffic ranges. The apparatus may associate a road segment in a corresponding traffic range based on the road segment identifier satisfying one bloom filter of the traffic range and provide the traffic range as traffic data for the road segment to a navigation application.
