1. A method comprising: in response to one or more changes of context associated with a device, a user of the device, or a combination thereof, generating, by an apparatus, at least one transition index structure via projecting a transition of the device into at least one index structure, wherein the context includes one or more user trip characteristics and locations, and the transition of the device includes the one or more changes of the context; associating, by the apparatus, the at least one transition index structure with one or more index objects corresponding to a sub-set of spatially related data objects associated with the at least one index structure, one or more other data objects, or a combination thereof and in response to a query for one or more of the spatially related data objects, searching, by the apparatus, via the at least one transition index structure to resolve the query.
