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