In a method and apparatus for navigating, mapping data is provided that includes geographical mapping point data with altitude information. A user is able to select a journey from a geographical start point to a geographical end point and to select at least one desired gradient parameter for the journey. At least one route is computed from the geographical start point to the geographical end point dependent upon the desired gradient parameters and the mapping data. The computed routing(s) can then be presented to the user. The accompanying figure shows an example method of selecting routing parameters. |
