Georeferenced imagery extract used only to check the WGS84 reading of the filed building outlines. Qualitative registration check only: the Edificio A and B outlines fall on the cleared brownfield lot bounded by the motorway to the west, the railway to the north and the Rho Fiera car parks to the east, and the four Gauss-Boaga well points fall at the south-east edge of Edificio B. This is not a measured accuracy and not a status observation. evidence
