Digital model of CyL terrain
Description
Digital Model of the Land of Castilla y León 2008-2011 at 5 m./pix.
Map of elevations representing, on a mesh or GRID (mesh step of 5 m.), the altitudinal values of the land of Castilla y León and its spatial distribution over the territory.
For SW quadrant:
• The accuracy in Middle Quadratic Error oscillates around 80 cm, with errors of up to 2 meters.
• These data have been obtained by stereocorrelation of digital images, and have subsequently been edited in 3D.
For the NW, NE and SE quadrants.
• The accuracy in Middle Quadratic Error oscillates around 20 cm, with errors of up to 2 meters.
• Data obtained by smoothing from LIDAR data (floor).
These data are the same as in the MDT-LIDAR section of the IGN-CNIG.
