Underpasses

The Wizard system’s Underflows target category belongs under the Target Points and Spaces dataset in the Target Register. The information in the object category of Sub-passage is located in the road register TL 262 under the Underground data type. The descriptions of the properties and the correspondence between the target category and the type of data in the Road Register can be found here at https://ohje.velho.vaylapilvi.fi/tietokuvaus/#Ominaisuustietokuvaukset. Description of road register TL 262: “All obstacles on the road that limit the altitude of the road shall be included in the road register. For electric cables, etc., only railway and tramway cables are recorded. The road address of the underpass is determined by the midway barrier (e.g. middle lines of intersecting roads).." Note! In Velho, Portals and Bridges are their own target categories.
