Combining Static and Dynamic Map Data

A method for determining map data, comprising:

• acquiring dynamic map data that is referenced to a geographical location;
• determining static map data in different versions,
• wherein static map data of each version describe a route network in an area of the geographical location,
• wherein unique identifiers are assigned to predetermined locations in the static map data;
• determining identifiers which represent a location of the dynamic map data in the different versions of the static map data;
• and
• providing the dynamic map data together with corresponding determined identifiers.

A method for determining map data, wherein the method comprises the following steps:

• determining a version of locally available static map data,
• wherein the static map data describe a route network and a unique identifier is assigned in each case to each of a set of predetermined locations in the route network;
• requesting dynamic map data relating to the determined version;
• and
• receiving dynamic map data and identifiers assigned to the dynamic map data.

A device for determining map data, wherein the device comprises:

• a first data memory for dynamic map data which are referenced to a geographical location;
• a second data memory for static map data in different versions,
• wherein static map data of each version describes a route network in the area of the geographical location,
• wherein a unique identifier is assigned in each case to predetermined locations in the route network of a version;
• a processing device which is configured to determine identifiers which represent a location of dynamic map data in the static map data of the different versions;
• and
• to provide dynamic map data together with the determined identifiers.

A device for determining map data, wherein the device comprises:

• a data memory for static map data in a version,
• wherein the static map data describe a route network and a unique identifier is assigned in each case to predetermined locations in the route network;
• a communication device configured to request dynamic map data relating to the version;
• and to receive dynamic map data and identifiers assigned to the dynamic map data.
