Height data — State road network

The data product consists of points with attributes of N- and E-coordinates in SWEREF99TM and altitude, H, in RH2000 along the state car cycle and walking network. An FME script runs monthly and generates points at nodes and breakpoints from the valid reference link parts found in NVDB. Attributes are created to keep the coordinate values that are rounded to decimeter accuracy. They are otherwise not changed so for height values there may be values -99999 which represent that there is no height recorded for the point (also missing on the reference link part). The association type is linked to the Swedish road network. The data product is part of NVDB, a database containing data on Sweden’s roads. The aim is to easily make available basic height data for the state road network.
