Claim Text:
1. A navigation apparatus comprising: a processing resource arranged to support, when in use, an operational environment, the operational environment supporting a route calculator, a time estimation module, a route segmentation module and a weather data processing engine; a map database comprising geospatial data; the route calculator arranged to calculate, when in use, a route between a first location and a second location; the time estimation module arranged to estimate a time at which a user will be present at a location along the route; the route segmentation module arranged to divide the route into a plurality of route parts and to obtain from the time estimation module at least one time of presence associated with at least one of the plurality of route parts; the weather data processing engine arranged to provide weather data associated with a route part of the plurality of route parts in respect of the time of presence associated with the route part for a plurality of journey start times, the providing of the weather data comprising partitioning weather data for two or more areas on the route based at least in part on corresponding radii or curves in a pattern in a corresponding weather front; and a user interface module arranged to communicate to the user the weather data in respect of a number of the plurality of route parts and at respective times of presence associated with the number of the plurality of route parts, the weather data being communicated graphically in combination with a map to show weather conditions outside the route than have been or will be missed at the respective times of presence associated with the number of a plurality of route parts; wherein the user interface is arranged to receive an instruction to re-calculate the route after communicating the weather data by changing the journey start time, and is further arranged to request updated weather data associated with a route part of the plurality of route parts in respect of the time of presence associated with the route part and to communicate the updated weather data to the user in combination with a map to show weather conditions outside the recalculated route than have been or will be missed at the respective times of presence.
