Method and apparatus for access point recording using a position device

1. A method for providing guidance with a positioning device comprising:

identifying a first venue;

identifying a plurality of second access points at a second venue;

determining the positioning device is near the second venue;

detecting the positioning device is off-route at an off-route location;

storing the off-route location as a first access point associated with the first venue on the map;

periodically determining location of the positioning device from the off-route location until the positioning device switches an operation mode;

providing guidance back to the first access point after the positioning device switches the operation mode;

generating a set of alternative routes by performing point-to-point routing from the first access point to the plurality of second access points;

selecting a best route among the set of alternative routes according to a predetermined criterion; and

using the positioning device to provide guidance from the first venue to the second venue along the best route.

2. The method of claim 1 further comprising adding another first access point previously not indicated on the map to the first venue after a user accessing the first venue through the another first access point.

3. The method of claim 1 wherein the first venue is a building, a building complex, and/or a parking lot.

4. The method of claim 1 wherein the predetermined criterion is selecting a route having a shortest length between the first access point and the second venue.

5. The method of claim 1 wherein predetermined criterion is selecting a route having a shortest projected travel time between the first access point and the second venue.

6. The method of claim 1 further comprising determining whether to enable or disable a shortcut segment for routing.

7. The method of claim 6 wherein determining whether to enable or disable the shortcut segment for routing is making the shortcut segment available for generation of all routes, generation of routes in pedestrian mode and/or generation of routes in vehicle mode.

8. The method of claim 1 wherein the first access point is an exit of the first venue, the second access points are entrances of the second venue.

9. A positioning device using a map having a plurality of segments, the positioning device comprising a program for performing the method of claim 1 .

10. A machine-readable medium that provides instructions for a processor, which when executed by the processor causes the processor to perform the method of claim 1 .
