A technique is disclosed for enabling collection and/or refinement of digital map information for aiding navigation route planning for vehicles larger than ordinary cars, such as goods-vehicles, buses, and car+caravan combinations. In at least one embodiment, a profile of a vehicle's characteristics, and one or more routes followed, are logged by a navigation device, and fed-back to a server that supports the navigation device with map data updates. At the server, or an alternative processing centre, the fed-back data from plural navigation devices is analysed to observe statistically the patterns of roads used by these vehicles, and to categorise these by the type of vehicle.
