Digital Model of the Land of Andalusia

The Digital Ground Models (MDT) of Andalusia are generated through stereocorrelation from the different photogrammetric flights included in the National Plan for Air Orthophotography (PNOA), together with GPS and IMU information, field support and aerotriangulation, to which an important process of quality control and manual editing is added. Depending on the spatial resolution of the different flights, a certain spatial resolution is generated in the Digital Ground Models (MDTs). To date, the corresponding ones have been made for the years 2008-2009, with a spatial resolution of 10x10 meters, and those of the years 2013 (in preparation) and 2016 with a spatial resolution of 5x5 meters. The MDT 2008-2009 can be downloaded directly by MTN 1:50,000 sheets in TIFF format on the download website (Line@) and, both this and 2016, through its corresponding WMS services.The Digital Ground Models (MDT) of Andalusia are generated through stereocorrelation from the different photogrammetric flights included in the National Plan for Air Orthophotography (PNOA), together with GPS and IMU information, field support and aerotriangulation, to which an important process of quality control and manual editing is added.
