The tower itself carries data data regarding the material, hight, year of manufactory etc.Related to the SupportStructure are MountingConnections each being related to (typically three) mounting points.A transmission tower carrying two 3-phase circuits will have 2 instances of MountingConnection, each of which will have 3 MountingPoint instances, one for each phase all with coordinates relative to a common origin on the tower. (It may also have a 3rd Connection with a single MountingPoint for the Neutral line).The supportstructure (tower) has a rotation angle allowing for 'decoding' the MountingPoint local coordinates into absolute coordinates.", "summary": "", "title": "Tower", "tags": [], "type": "", "typeKeywords": [], "thumbnail": "", "url": "", "minScale": "NaN", "maxScale": "NaN", "spatialReference": "", "accessInformation": "", "licenseInfo": "", "portalUrl": "" }
