Method of creating map data
First Claim
1. A computerised method of creating map data from a plurality of trips where each trip comprises position data derived from the positions of at least one navigation device over a period of time, the method comprising using a processing circuitry to perform the following steps:
- processing the position data;
calculating, from the processing of the position data, trip terminal positions at which the navigation device started to generate positions and/or stopped generating positions and which provide an end point of a trip;
performing statistical analysis on the terminal positions in order to determine origin locations at which trips commonly terminate and/or originate;
identifying, based on each of the origin locations, a location of an entrance and/or exit to a corresponding structure; and
incorporating the origin locations into map data, the incorporating comprising placing, in the map data, indications of the locations of entrances and/or exits of the corresponding structures for each of the origin locations.

Abstract
A computerized method of creating map data from a plurality of trips where each trip comprises position data derived from the positions of at least one navigation device over a period of time, the method comprising using a processing circuitry to perform the following steps: i. processing the position data; ii. calculating, from the processing of the position data, trip terminal positions at which the navigation device started to generate positions and/or stopped generating positions and which provide an end point of a trip; iii. performing statistical analysis on the terminal positions in order to determine origin locations at which trips commonly terminate and/or originate; iv. generating further map data, which comprises the origin locations.

17. A machine comprising a processor and memory and arranged to create map data, wherein the machine is arranged to receive and process position data from at least one source, the position data comprises the positions of at least one navigation device over a period of time, the machine being arranged to:
-
process the position data; calculate trip terminal positions at which the navigation device generating that trip started to generate and/or stopped generating positions; perform statistical processing on the terminal positions between the trips in order to determine origin locations at which a plurality of trips terminate and/or originate; identify, based on each of the origin locations, a location of an entrance and/or exit to a corresponding structure; and incorporate the origin locations into map data, the incorporating comprising placing, in the map data, indications of the locations of entrances and/or exits of the corresponding structures for each of the origin locations. - View Dependent Claims (18, 19)

20. A non-transitory machine readable medium containing instructions which, when executed by a machine, cause the machine to perform a method for creating map data from a plurality of trips, each trip comprising position data derived from positions of at least one navigation device over a period of time, the method comprising:
-
processing the position data; calculating, based on the processing of the position data, trip terminal positions at which the navigation device started to generate positions and/or stopped generating positions and which provide an end point of a trip; performing a statistical analysis on the terminal positions to determine origin locations at which trips commonly terminate and/or originate; identifying, based on each of the origin locations, a location of an entrance and/or exit to a corresponding structure; and incorporating the origin locations into map data, the incorporating comprising placing, in the map data, indications of the locations of entrances and/or exits of the corresponding structures for each of the origin locations.
