Soundproofing devices (GWV) — Sideline height

Soundproofing facilities (GWV). A GWV file is delivered/created annually, which describes the situation on 31-12 of that year. The GWV file contains, among other things, the following sound-resistant objects: 1. Soundwalls 2. Sound screens 3. Tunnel entrances 4. Deepened reclining road sections. The data in the GWV file consists of: 1. Geometry of the object 2. Descriptive features of the object that are important for the sound-resistant function 3. Photos of the object. The reason for the changes to the GWV file can be divided into 3 categories: 1. New location facilities. 2. Changes due to the placement of smaller facilities or extension of existing facilities. 3. Changes due to the demolition of facilities. Height side stripe: The x and y coordinates in the RD/NAP system of points on the upper edge of the Noise Resistant Provisions segment in [meters]. The z-coordinates shall be the height in the NAP system of the cross-stripe at each nod point of an anti-noise device in [meters].
