In this way, the State of Pernambuco becomes one of the few Brazilian States to own the whole mapping of its territorial area.
The State of Pernambuco, through the Office of Energy and Water Resources in partnership with the International Bank for reconstruction and development (IBRD), hired the Consortium Águas de Pernambuco, which Engefoto was the leading company to perform air cover with GSD (GroundSampleDistance) of 50 cm around the State, totaling more than 98,000 km², as well as air cover with GSD (GroundSampleDistance) of 12 cm of the urban areas of all the 185 municipalities, totaling 870 km².
The airborne laser profiling has already been carried out using altimetry precision better than 25 cm of the entire state extension. In the urban areas of the municipalities, the laser altimetry accuracy was better than 10 cm. Besides that, geodesic landmarks were implemented in urbanized areas. This aimed subsequent mapping updates by any method, and it can be Topography, GNSS Positioning, Aerophotogrammetry or Satellite Images. This material has generated topographic maps at scales of 1:5,000 (the whole State) and 1:1,000 (urban areas).
This project provides a base of information for important services to be made by the State, whether it is Transnordestina Railway or River Transposition of River São Francisco. In this way, the State of Pernambuco becomes one of the few Brazilian States to own the whole mapping of its territorial area.
