Method and system for displaying nowcasts along a route on a map
First Claim
1. A computer implemented method for generating a map for ground navigation comprising a weather forecast, the method comprising:
- receiving, at a navigation device, a map request indicating a departure location and a destination location;
in response to receiving said map request, obtaining map data associated with a route between the departure location and the destination location;
obtaining a plurality of precipitation forecasts, each precipitation forecast indicating a probability of a different one of a plurality of precipitation types occurring at a point along the route at an estimated time of arrival (ETA) associated with the point;
obtaining a plurality of rate forecasts, each rate forecast indicating a probability of a different one of a plurality of precipitation rates occurring at the point at the ETA;
combining the plurality of precipitation forecasts and the plurality of rate forecasts to generate a probability distribution indicating probabilities that each of the plurality of precipitation types will occur at each of the plurality of precipitation rates at the point at the ETA; and
displaying, on a display device of the navigation device, a map of the route and a visual indicator of at least one probability in the distribution.

Abstract
A system and method for displaying nowcasts along a route on a map. The system receives a map request including a departure location and a destination location from a user, and obtains map data including a route between the destination location and the departure location. A nowcaster is used for outputting nowcasts for a number of key points along the route. The system modifies the map data to include a visual indicator for each nowcast for each key point such that when the modified map data is executed on a display the nowcasts are displayed along the route between the departure location and the destination location.

5. A non-transitory computer readable medium storing instructions, which when executed by a navigation device with a display, cause the navigation device to:
-
receive a map request including a departure location and a destination location; in response to receiving said map request, obtain map data associated with a route between the departure location and the destination location; obtain a plurality of precipitation forecasts, each precipitation forecast indicating a probability of a different one of a plurality of precipitation types occurring at a point along the route at an estimated time of arrival (ETA) associated with the point; obtain a plurality of rate forecasts, each rate forecast indicating a probability of a different one of a plurality of precipitation rates occurring at the point at the ETA; combine the plurality of precipitation forecasts and the plurality of rate forecasts to generate a probability distribution indicating probabilities that each of the plurality of precipitation types will occur at each of the plurality of precipitation rates at the point at the ETA; and display, on the display of the navigation device, a map of the route and a visual indicator of at least one probability in the distribution.

6. A ground vehicle navigation apparatus comprising:
-
a display device; one or more processors; a memory comprising instructions which when executed by the one or more processors cause the ground vehicle navigation apparatus to; receive a map request indicating a departure location and a destination location; in response to receiving said map request, obtain map data associated with a route between the departure location and the destination location; obtain a plurality of precipitation forecasts, each precipitation forecast indicating a probability of a different one of a plurality of precipitation types occurring at a point along the route at an estimated time of arrival (ETA) associated with the point; obtain a plurality of rate forecasts, each rate forecast indicating a probability of a different one of a plurality of precipitation rates occurring at the point at the ETA; combine the plurality of precipitation forecasts and the plurality of rate forecasts to generate a probability distribution indicating probabilities that each of the plurality of precipitation types will occur at each of the plurality of precipitation rates at the point at the ETA; and display, on the display device of the ground vehicle navigation apparatus, a map of the route and a visual indicator of at least one probability in the distribution. - View Dependent Claims (7, 8, 9, 17)
