Abstract
Systems, devices, and methods are provided for calculating a course for avoiding user identified criteria. A navigation device with route calculation capabilities includes a processor connected to an input and a memory that includes cartographic data and user identified criteria. A route calculation algorithm can be used to calculate a course between two or more waypoints based on the predefined user criteria of the cartographic data. Performing the route calculation algorithm includes analyzing the cartographic data with a preference for providing the course that identifies and avoids the user identified criteria. A display is connected to the processor and is capable of displaying the calculated route and cartographic data. The device is also adapted to dynamically analyze an area surrounding a present location for user identified criteria to avoid and display the results of the analysis.
