Regional trigonometric summits (TRV)
Description
Trust points determined during the construction of the regional cartography plant, carried out in successive batches. The network of trigonometric verticals (VT) IGM has been conveniently refined, establishing a derived network of Regional Trigonometric Verticals (TRVs) materialised on the ground, obtaining a total density of about 1 point per 1000 hectares. The reliability of the determinations of the abovementioned VTs and VTRs (defined by the numerical coordinates derived from the catalogues, and not those measured on paper) is characterised by errors which, in 90 % of cases, do not exceed 0,5 metres in any of the three coordinates.
