Abstract: Dynamic Location Referencing in Inspire
How do you improve the usability of Inspire datasets and ensure users using their own maps and applications correctly utilize them?
Dataset within the Inspire infrastructure refer to a location. A location comes to life when geometry and its coordinate reference system (CRS) are used on a digital map (context). A map is needed to provide spatial context information to answer questions like; On which road lane is this data measured?
There are many different digital maps available to the user. Maps have significant differences in quality introducing a number of technical issues. Maps differ in coverage, naming conventions, geometry, data model semantics and map attributes (features) and not all maps can be used for route planning applications. Last but not least maps are frequently updated to reflect real-world changes and no guarantees are made that network links and attributes stored in a map remain unchanged.
Transport and traffic management applications and services need a method to relate data to a network (e.g. road network) that is independent of the network geometry stored in a specific map. Within the GCM, the Generic Network Model (GNM) of INSPIRE, Linear referencing (ISO 19148) is currently the only location referencing method available.
Linear referencing is widely used to exchange static road data and works well when a sender (e.g. a public road authority) and a receiver (e.g. a service provider) use a common definition within the linear referencing system. Traffic Message Channel (TMC) is an example of a linear referencing system currently used in the exchange of traffic information in the European DATEX2 standard. However linear referencing methods have a number of challenges because definitions rely on a set of pre-defined locations and common definitions between member states do not exist. Changes made to these pre-defined locations often result in inconsistencies. Furthermore the coverage of a transport network is largely depended on the number of pre-defined locations chosen in the definition. This means not all roads in a transport network can be fully addressed.
In this presentation we will discuss how dynamic on-the-fly location referencing can solve these challenges and make it possible to accurately describe a location independently of a map. We will provide a number of real world use cases where governments and businesses successfully employ dynamic location referencing in their day-to-day operation.
We hope this presentation will help in creating awareness surrounding the subject of dynamic location referencing and show the value dynamic location referencing could add to the Inspire data harmonisation process.
