WMS Ortophoto Year 2020-2021

Orthophoto WMS Service. Images obtained from photogrammetric flights with GSD of 20 cm/pixel, ortorectified from orientations obtained by aerotriangulation processes and corrected chromatically by semi-automatic processes. Resolution of 20 cm/pixel. Planimetric error less than 1 m (RMS < 1 m). Due to the absence of photogrammetric flight of 2020, the orthophotos have had to be used, in some islands, satellite images (original resolution 50 cm/pixel) or images collected by the medium format camera of the lidar flight (original resolution 25 cm/pixel). For the elaboration of the orthophotos of Fuerteventura and Tenerife, part of photogrammetric flight GSD 20 cm/pixel and part of satellite images of 50 cm/pixel have been used. For the orthophoto of La Palma we have used images obtained from the mid-format camera of the LIDAR flight and with approximately 25 cm/pixel GSD, and satellite images at 50 cm/pixel. For La Gomera, the images used in the elaboration of the orthophoto have been obtained from the satellite at 50 cm/pixel. For the orthophotos of El Hierro and Lanzarote, images obtained from the mid-format camera of the LIDAR flight and with approximately 25 cm/pixel GSD have been used. The flight dates for the orthophoto are: The Iron: July-August 2020 La Palma: August-December 2020 La Gomera: October 2020-January 2021 Tenerife: May 2020-January 2021 Gran Canaria: May 2020-February 2021 Fuerteventura: July-September 2020 Lanzarote: August 2020
