Data service

The acquisition, creation, processing, management and provision of geodata play a central role in the operation of test fields. Therefore, special emphasis is placed on standardised data management in order to make such diverse geodata easily accessible for the widest possible range of applications – for example, for partners from industry and scientific research or customers for their own tests.

Data are preferably made available via standardised interfaces (GeoServer). Some data sets are supplemented with metadata (GeoNetwork). These data services form an abstracted interface to data in the AIM backend and facilitate access to it.

How you benefit from the data services

• Traffic data can be made available to customers and external partners

• Information on the traffic situation in the field, locations of traffic lights and signs

• Provision of digital maps and property registry data

• Data services are collected throughout the year and under different conditions (traffic situation, weather conditions, various research vehicles)

• Always up-to-date data
  

Application

The representation of real routes in the Test Bed Lower Saxony, in the form of highly accurate digital maps, promotes the comparability as well as testing of models or development statuses that are used both in simulations and in real test vehicles on public roads.

Among other things, the following can be made available:

• Road topography / topology
• Terrain and building models
• Information on the traffic situation in the field as well as the location of signs and traffic lights
• Research datasets with standardised metadata

The datasets provided serve as exemplary samples for checking for embeddability of the data in the client’s research and development or verification and validation tool chains.
