Abstract

A method and device for coding, decoding and/or transmitting location data is proposed, a path and a main path encompassing points; the at least one path being provided as a subpath with respect to the main path; at least one path point, as a branching point, being identical to a main point and the location data being arranged according to the data format in the sequence of the main points.

Claims

1. A method for coding, decoding and/or transmitting location data in accordance with a data format,

the location data encompassing a plurality of points, wherein

at least one path and one main path are coded, decoded and/or transmitted;

the main path and the at least one path together encompassing the plurality of points;

the main path encompassing a plurality of main points of the plurality of points;

the at least one path encompassing a plurality of path points;

the at least one path being provided as a subpath with respect to the main path;

at least one path point, as a branching point, being identical to a main point; and

the location data being arranged according to the data format in the sequence of the main points.

2. The method as recited in claim 1, wherein the location data encompass a plurality of paths;

a second path is a subpath with respect to a first path, at least one path point of the second path as a branching point being identical to a path point of the first path.

3. The method as recited in one of the preceding claims, wherein the at least one path point of the second path, which is a subpath with respect to the first path, is the initial point of the second path.

4. The method as recited in one of the preceding claims, wherein in the coding of location data, for a predefined plurality of points the definition of the main path and of the at least one path (=partitioning) is undertaken as a function of a partitioning parameter.

5. The method as recited in claim 4, wherein the partitioning parameter is the point-to-point resistance associated with a point-to-point connection between two points of the plurality of points.

6. The method as recited in claim 4, wherein the partitioning parameter is associated with the road designation and/or the road category of a point-to-point connection between two points of the plurality of points.

7. The method as recited in one of the preceding claims, wherein open paths are provided.

8. The method as recited in one of the preceding claims, wherein the paths form closed loops.

9. The method as recited in one of the preceding claims, wherein in addition to the plurality of points new points and/or new point-to-point connections are integrated into the location data, the description of the plurality of points being maintained.

10. The method as recited in one of the preceding claims, wherein the data format provides associating an attribute to a point of the plurality of points or to several points of the plurality of points.

11. The method as recited in one of the preceding claims, wherein the data format provides the representation of location data according to a description language (markup language), especially XML-based (extended markup language).

12. A device for coding, decoding and/or transmitting location data in accordance with a method as recited in one of the preceding claims.
