Geographic Coverage

The MulitNet® database is constantly being updated and improved. The geographic coverage of the database also is expanding. Please refer to the MultiNet® Release Notes for this release or contact a TomTom® Sales and Marketing representative through the TomTom website for details of current and planned coverage.

Road Networks

TomTom® is continually improving road network coverage throughout the world. There are three levels of MultiNet® road networks available for represented countries:
  • Major Road Network (MRNW)
    • The Major Road Network covers freeways, motorways and limited-access highways. Connector Roads are a subset of the MRNW.
  • Interconnecting Network (ICNW)
    • The Interconnecting Network covers all geometry included in the MRNW and also includes local connecting roads and local roads of high importance.
  • Street Network (STNW)
    • The Street Network represents the entire road network, including local roads.
Please contact a TomTom® Sales and Marketing representative through the TomTom website (www.tomtom.com) for the current level of network coverage for your geographic area.

Data Partitioning

MultiNet® data is delivered by nation. For most countries, each nation database is partitioned with a hierarchy of Administrative Areas. Country is the highest level-Order 0-and submunicipality (Hamlet) is the lowest possible level-Order 9.

For data partitioning structure, see the MultiNet Global Directory and File Naming Conventions document included in the specs folder of this documentation DVD.

Depending on the country, only some of the intermediate orders may be present.

Data Delivery

Delivery methods from TomTom® may vary depending on how your data is partitioned and packaged. In order for certain GIS format applications to open and display data files correctly on your computer, copy all data from the DVD or DVD(s) to your hard drive following the same directory structure as it appears on the DVDs. The directory structure and file naming are detailed in the MultiNet Global Directory and File Naming Conventions document.
