Andalusian Terreno Digital Model

Andalusia’s Digital Land Models (TDM) are generated by stereocorrelation from the various photogrammetrical flights included in the National Plan for Air Orthography (PNOA), together with GPS and IMU information, field support and aerotriangulation, together with an important quality control and manual editing process. Depending on the spatial resolution of the different flights, a determined spatial resolution is generated in the Digital Land Models (TDM). To date, those for the years 2008-2009 have been carried out, with a spatial resolution of 10x10 metres, and those for 2013 (under preparation) and 2016 with a spatial resolution of 5x5 metres. The TDM 2008-2009 can be directly downloaded on MTN 1: 50.000 sheets in TIFF format on the Line @. Both the East and 2016, through their corresponding WMS services.
