First Claim
Patent Images
1. A method performed in a device for providing navigation instructions in a three-dimensional map environment, comprising:
- receiving a start position and an end position;
determining a route from said start position to said end position;
determining, for a position on said route, graphical two-dimensional map data related to said position;
retrieving said graphical two-dimensional map data;
generating, for said position of said route, navigation instructions by;
projecting said graphical two-dimensional map data on a plane in a three-dimensional map environment and adding a representation of said route;
adding graphical three-dimensional map objects to said projected graphical two-dimensional map data by utilising said graphical three-dimensional map objects data; and
setting a transparency level of said graphical three-dimensional map objects; and
transmitting said navigation instructions to a display.

13. A device for providing navigation instructions in a three-dimensional map environment, comprising:
-
a receiver for receiving a start position and an end position, a processing unit that; determines a route from said start position to said end position; determines, for a position on said route, graphical two-dimensional map data related to said position; retrieves said graphical two-dimensional map data, and generates, for said position of said route, navigation instructions by; projecting said graphical two-dimensional map data on a plane in a three-dimensional map environment and adding a representation of said route; adding graphical three-dimensional map objects to said projected graphical two-dimensional map data by utilising said graphical three-dimensional map objects data; and setting a transparency level of said graphical three-dimensional map objects; and a transmitter for transmitting said navigation instructions. - View Dependent Claims (14)

15. A computer program product stored on a computer-readable medium comprising computer program code portions, the computer program product comprising:
-
executable code that receives a start position and an end position; executable code that determines a route from said start position to said end position; executable code that determines, for a position on said route, graphical two-dimensional map data related to said position; executable code that retrieves said graphical two-dimensional map data; executable code that generates, for said position of said route, navigation instructions by; projecting said graphical two-dimensional map data on a plane in a three-dimensional map environment and adding a representation of said route; adding graphical three-dimensional map objects to said projected graphical two-dimensional map data by utilising said graphical three-dimensional map objects data; and setting a transparency level of said graphical three-dimensional map objects; and executable code that transmits said navigation instructions to a display. - View Dependent Claims (16, 17, 18, 19, 20)
