Introduction

Street-Routing functionality requires vector data with a classified topology of the road network. In QuoVadis, this requires our NAVTEQ® map compilations.


Currently, we can offer these maps for a total of 54 countries which are sampled in the following product coverages:

  • Germany, Austria, Switzerland.
  • Western Europe including Andorra, Austria, Belgium, Denmark, Eire (Republic of Ireland), Faroe Islands, Finland, France, Germany, Gibraltar, Greece, Greenland, Guernsey, Iceland, Italy/Vatican City, Jersey, Liechtenstein, Luxembourg, Monaco, Norway, Portugal, San Marino, Spain, Sweden, Switzerland, The Netherlands, United Kingdom.
  • The whole of Europe including Albania, Andorra, Austria, Belarus, Belgium, Bosnia & Herzegovina, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Eire (Republic of Ireland), Estonia, Faroe Islands, Finland, France, Germany, Gibraltar, Greece, Greenland, Guernsey, Hungary, Iceland, Italy/Vatican City, Jersey, Latvia, Liechtenstein, Lithuania, Luxembourg, Macedonia, Moldova, Monaco, Norway, Poland, Portugal, Romania, Russia, San Marino, Serbia & Montenegro, Slovakia, Slovenia, Spain, Sweden, Switzerland, The Netherlands, Turkey, Ukraine, United Kingdom.
  • Northern America including USA, Canada, Mexico.
  • Southern Afrika including Southafrica, Namibia, Bostwana, Mosambique, Lesotho, Swaziland.


Please note that the NAVTEQ® map are mainly limited to the public road network. So you should not expect forest roads or tracks to be included in this vector topology!


We offer these maps in two versions with different functionality:

This version allows for a route planer functionality. So, using a NAVTEQ® Routing map, you can calculate routes from address A to address B according to various preferences (see Street-Routing Preferences). You can also account for stop-over points which can be searched from the address database or be specified directly in the map. The calculated route is listed as a summary statistics and as a list of navigation instructions. It can also be stored as a track or a route and thus can be uploaded to compatible GPS devices.

However, it is important to consider several points when uploading such data to a GPS device:

  • For a turn-by-turn navigation you need a GPS device with autorouting capabilities.
  • Most GPS devices will only be able to use an uploaded route for turn-by-turn navigation. A track can only be displayed as a “guideline where to drive” without turn-by-turn navigation. An exception of this are the Garmin® Zumos which can convert a track to a route.
  • Beware that most GPS devices cannot handle too many stop-over-points. Any point along the route where a navigational choice has to be made, will be considered as a “stop-over-point” by the GPS device. So may routes are simply too long for such a purpose.
  • The GPS device will always use its own logic to find the best route between stop-over-points. This will be calculated according to the priority set in the routable GPS device.
  • Therfore, it is of high importance to specify stop-over points in a way that you need a) as few points as possible to define a route, and b) in a way that your GPS unit has little chance to recalculate something which is not in aggreement with your original intension. Therfore we recommend to define stop-over-points not by enetering a point in the cities and settlements which you want to visit but on the roads in between. We also recommend to upload such a route before you calculated the complete tour in QV. Thus you can “fix” a tour with comparably few points and you GPS device won't get overloaded with stop-over-points. Therafter make the route calculation to see how long it is going to take, how much fuel you are going to need, and so on. Just make some test with the route consisting of the stop-over-points and the result of the calculated route and you will quickly understand what its all about…

This version includes the complete route planer functionality decribed above. Additionally, it offers dynamic autorouting capabilities, so real turn-by-turn navigation with optional voice-guidance and an automatic route reclaculation in case you lost your original track. So, generally a NAVTEQ® Navi map only makes sense if you use your notebook or tablet-PC in your vehicle for online navigation.

Concerning route planning and upload of routes and tracks to your GPS device everything stated above also holds true when using this version of the NAVTEQ® map.


Please note that the licence agreement for the NAVTEQ® Routing and Navi map versions are only valid for non-comercial use.

For remote tracking applications like fleet tracking or monitoring of other objects on a headquarter PC application, other NAVTEQ® licence models are required. In this case please contact us under support@qvgps.com.


Please note that we cannot guarantee for the correctness of a calculated route! You are always responsible for driving inaccordance with valid traffic regulations even if a calculated route will suggest something different. The routing functionality of QuoVadis is a helpful aid to make strret-navigation more comfortable. However we cannot be made responsible for incorrect or misleading navigation instructions. The reponsibility for safetey during public traffic lies always in the responsibility of the driver!
