The Publication 3/2016 includes the Barrier data object for the first time. The data object improves reliability of the navigation services. Data are retrieved in principle from the Topographic database of the NLS.
We would also like to remind that starting from the Digiroad Publication 2/2016, the link ID (LINK_ID) is used as a unique road link ID. Therefore, MML-ID by the National Land Survey (NLS) will not be used as a reference point between the road links and attribute data but all the attribute data can be linked to the road link geometry with the link ID (LINK_ID) and measure (M-value). MML-ID will continue to be published as part of the attribute data of the road links.
In addition, we remind that all the directions of digitisation in the road links have been unified according to the cardinal directions. The starting point of a road link is always the southern endpoint of the link. However, the starting point of a link in the fully East-West direction is the western endpoint. Due to the unification of the directions of digitisation, the first house number on the right and left side may be larger than the final house number on the right and left side.
A ReadMe file explaining the data objects and data structure is available on the new Digiroad website > Documents. No separate quality reports are attached to the publication.
The next Digiroad Publication is scheduled for August 2016. The road link geometry in the next publication will be updated to the situation as of August.
