Description
Orthophotos WMS service. Images obtained from orthorectified photogrammetric flights from orientations obtained by aerotriangulation processes and adjusted chromatically by semi-automatic processes. 16 cm/pixel orthophotos have been obtained with Artificial Intelligence (AI) techniques based on those generated at 20 cm/pixel. In addition, the service contains three 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, Fuerteventura and Gran Canaria.
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 12/02/2023 to 15/03/2023 (project 247).
Tenerife of 16 cm/pixel, generated from a flight GSD 20 cm/pixel executed from 15/01/2023 to 15/03/2023 (project 247).
Fuerteventura of 10 cm/pixel, obtained from the flight GSD 11 cm/pixel made from 14/01/2023 to 25/03/2023 (project 247).
Lanzarote of 16 cm/pixel, obtained from the flight GSD 20 cm/pixel made from 02/10/2023 to 03/10/2023 (project 247).
