Method and system for displaying nowcasts along a route map
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.
1. A computer implemented method for generating a map comprising a weather forecast, the method comprising:
receiving, at a navigation device, a map request including a departure location and a destination location;
in response to receiving the map request, obtaining map data associated with a route between the departure location and the destination location;
generating a weather forecast indicating a probability of a particular type of precipitation occurring at a particular rate at a point along the route at an estimated arrival time associated with the point by combining a probability of the particular type of precipitation occurring and a probability of precipitation occurring at the particular rate; and
displaying, on a display device of the navigation device, a map of the route and a visual indicator of the weather forecast.
2. The method of claim 1 , wherein obtaining the weather forecast comprises:
sending location information associated with the point to a remote server; and
receiving the weather forecast from the remote server.
3. The method of claim 2 , wherein obtaining the weather forecast further comprises sending, to the remote server, the estimated arrival time.
4. The method of claim 3 , further comprising:
determining the estimated arrival time based on a current time, a distance between the point and the departure location, and another weather forecast.
5. The method of claim 1 , wherein the weather forecast further indicates a second probability of a second particular type of precipitation occurring at a second particular rate at the point at the estimated arrival time.
6. The method of claim 1 , further comprising:
selecting the point based on stored user preferences;
identifying a second point along the route based on the stored user preferences; and
obtaining a second weather forecast indicating a second probability of the particular type of precipitation occurring at the particular rate at the second point at a second estimated time of arrival associated with the second point, wherein the stored user preferences identify an increment between the point and the second point.
7. The method of claim 6 , further comprising:
obtaining an updated weather forecast for the point based on advancement of the navigation device on the route and changes in weather conditions; and
displaying, on the display device, a modified map that includes a second visual indicator representing the updated weather forecast.
8. The method of claim 1 , wherein the map data is generated using information stored locally.
9. The method of claim 1 , further comprising:
forwarding the map request to a remote server; and
receiving the map data from the remote server.
10. The method of claim 1 , further comprising:
selecting the point based on stored user preferences, wherein the stored user preferences indicate that a user prefers to receive weather forecasts associated with major cities.
11. The method of claim 1 , wherein the particular type of precipitation is hail.
12. The method of claim 1 , wherein the weather forecast is associated with a 1-minute interval.
13. A device for generating a map comprising a weather forecast, the device comprising:
a display device;
one or more processors; and
a memory storing instructions for the one or more processors,
wherein, when the one or more processors execute the instructions stored in the memory, the device is caused to:
receive a map request indicating a departure location and a destination location;
in response to receiving the map request, obtain map data associated with a route between the departure location and the destination location;
obtain a weather forecast indicating a probability of a particular type of precipitation occurring at a particular rate at a point along the route at an estimated arrival time associated with the point, wherein the probability of the particular type of precipitation occurring at the particular rate is generated by combining a probability of the particular type of precipitation occurring and a probability of precipitation occurring at the particular rate; and
display a map of the route and a visual indicator of the weather forecast on the display device.
14. The device of claim 13 , wherein the point is selected based on stored user preferences and the stored user preferences indicate a preference for weather forecasts associated with major cities or identifying an interval between points.
15. A non-transitory computer readable medium storing instructions that, when executed by a processor, cause it to:
receive, at a navigation device, a map request including a departure location and a destination location;
in response to receiving the map request, obtain map data associated with a route between the departure location and the destination location;
generate a weather forecast indicating a probability of a particular type of precipitation occurring at a particular rate at a point along the route at an estimated arrival time associated with the point by combining a probability of the particular type of precipitation occurring and a probability of precipitation occurring at the particular rate; and
display, on a display device of the navigation device, a map of the route and a visual indicator of the weather forecast.
