Description
Orthophoto WMS Service. Images obtained from ortorrectified photogrammetric flights from orientations obtained by aerotriangulation processes and adjusted chromatically by semi-automatic processes. Orthophotos of 16 cm/pixel have been obtained with Artificial Intelligence (AI) techniques from those generated at 20 cm/pixel. In addition, the service contains two High Resolution Territorial Orthophotos at 10 cm/pixel obtained from those generated at 12.5 cm/pixel, thanks to the application of AI techniques for the islands of La Gomera and Fuerteventura.
The planimetric error is therefore divided into two:
less than 1 metres (RMS < 1 m) for orthophotos generated from flights with GSD 20 cm/pixel
less than 0.62 metres (RMS < 0.62 m) for orthophotos generated from flights with GSD 11 cm/pixel.
Flight data and resolution of orthophotos:
The 10 cm/pixel Gomera, obtained from the flight GSD 11 cm/pixel executed from 9/05/2022 to 15/05/2022 (project 242).
Tenerife of 16 cm/pixel, generated from a GSD flight 20 cm/pixel executed from 5/05/2022 to 10/08/2022 (project 241)
Fuerteventura of 10 cm/pixel, obtained from the flight GSD 11 cm/pixel made from 08/05/2022 to 19/08/2022 (project 242).
Lanzarote of 16 cm/pixel, obtained from the flight GSD 20 cm/pixel made from 19/08/2022 to 24/10/2022 (project 241)
The Palm of 16 cm/pixel, obtained from the flight GSD 20 cm/pixel made from 7/05/2022 to 7/06/2022 (project 241).
Gran Canaria of 16 cm/pixel, generated from a GSD flight 20 cm/pixel executed from 2/03/2022 to 15/06/2022 (project 241).
Iron of 16 cm/pixel, obtained from the flight GSD 20 cm/pixel made from 10/08/2022 to 22/08/2022 (project 241).
