Navigation device and method
First Claim
1. A navigation device comprising:
- a processor that is configured to generate a navigation map of a local environment;
a display controllable by said processor to display said navigation map and a marker for any one or more marked locations within said local environment; and
an indicator generation module for generating an indicator for any one or more marked locations outside of said local environment, said processor being responsive to said indicator generation module to control said display to display any generated indicators in said navigation map.

Abstract
This invention relates to a navigation device (200) comprising: a processor (210) that is configured to generate a navigation map of a local environment (497); and a display (240) controllable by said processor (200) to display said navigation map and any markers (489) that relate to marked locations within said local environment (497); characterised in that the navigation device (200) further comprises: an indicator generation module (490) for generating an indicator (491) for each of any marked locations outside of said local environment, said processor (210) being responsive to said indicator generation module (490) to control said display (240) to display any generated indicators (491) in said navigation map (497).
A method of generating a navigation map and a computer program are also disclosed.

1. A navigation device comprising:
-
a processor that is configured to generate a navigation map of a local environment; a display controllable by said processor to display said navigation map and a marker for any one or more marked locations within said local environment; and an indicator generation module for generating an indicator for any one or more marked locations outside of said local environment, said processor being responsive to said indicator generation module to control said display to display any generated indicators in said navigation map. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A method of displaying a navigation map, the method comprising:
-
generating a navigation map of a local environment; determining whether said local environment includes any marked locations, and retrieving for any one or more marked locations determined to be within said local environment a marker for display; determining whether there are any marked locations outside of said local environment; and
generating for one or more of any marked locations that are determined to be outside of said local environment an indicator for display; anddisplaying said navigation map, any said markers and any said indicators.

23. Computer software comprising one or more software modules operable, when executed in an execution environment, to cause a processor to:
-
generate a navigation map of a local environment; determine whether said local environment includes any marked locations, and retrieve for any one or more marked locations determined to be within said local environment a marker for display; determine whether there are any marked locations outside of said location environment; and
generate for one or more of any marked locations that are determined to be outside of said local environment an indicator for display; andcontrol a display to display said navigation map, any said markers and any said indicators.

24. A computer readable data storage medium having computer software stored thereon, said computer software comprising one or more software modules operable, when executed in an execution environment, to cause a processor to:
-
generate a navigation map of a local environment; determine whether said local environment includes any marked locations, and retrieve for any one or more marked locations determined to be within said local environment a marker for display; determine whether there are any marked locations outside of said location environment; and
generate for one or more of any marked locations that are determined to be outside of said local environment an indicator for display; andcontrol a display to display said navigation map, any said markers and any said indicators.

25. A portable navigation device (PND) comprising:
-
an antenna; a receiver operatively coupled to said antenna for receiving GPS data signals from a plurality of satellites; a store for map data and marker data, said marker data defining marker locations; an interface that is user operable for the input of a start location and a destination location; a processor operatively coupled to said interface, said receiver and said store, said processor being configured to; receive said GPS data signals from said receiver and to process said GPS data signals to determine a current position of said PND in a local environment, to generate from map data retrieved from said store a navigation map of the local environment in which said PND current position is located, and to calculate, from map data retrieved from said store, a route between said start location and said destination location; an indicator generation module controllable by said processor to generate an indicator for each of any one or more marker locations for which the associated marker data from said store indicates that said marker locations are outside of said local environment; and a display operatively coupled to said processor and controllable by said processor to display; said navigation map, a visual representation of said route, a marker for each of any one or more marker locations for which the associated marker data from said store indicates that said one or more marker locations are within said local environment; and any said indicators.
