TMC Location Structure in MultiNet® GDF Data
TMC Information is modeled in GDF in the following way:
In the TomTom® MultiNet® product the TMC Location References is stored on GDF Level 1 in the "RD" attribute of a Road or Ferry Element in the following way: "ABCCDEEEEE."
Where:
- A = Direction of Road Element (from start Junction to end Junction) compared
with the TMC chain direction:
- + = in positive direction and external to the TMC point location;
- - = in negative direction and external to the TMC point location;
- B = EBU (European Broadcasting Union) Country Code;
- CC = TMC Location Code;
- D = TMC Direction of the Chain;
- + = in positive direction and external to the TMC point location;
- - = in negative direction and external to the TMC point location;
- P = in positive direction and internal to the TMC point location;
- N = in negative direction and internal to the TMC point location.
- EEEEE = TMC Point Location Code (found in the official TMC location Databases).
The example below shows how the TMC attributes of the GDF Level 1 feature Road Element are stored in a GDF volume.
