WMS service. Integrated Topographic Map is drawn from existing Topographic Maps 1:5,000 and 1:1,000, which have been merged and updated using two flights: a low flight (digital flight GSD 8.4 cm/pixel, for urban areas) and a high flight (digital flight GSD 20 cm/pixel, for the rest of the zones) through the application of field support processes, aerotriangulation, photogrammetric restitution, digital editing and cartographic quality controls. Reference system ITRF93. Ellipsoid WGS84. REGCAN95 Geodesic Network (v2001). Projection system UTM Huso 28. Altitudes referring to the average sea level determined on each island.
The area affected by the eruption in La Palma in 2021 has been restored with precision 1:1,000, from a GSD 12 cm/pixel digital flight of project 244, carried out from 01/03/2022 to 01/05/2022. The rest of the island corresponds to integrated mapping 1:1,000-1:5,000 obtained from a GSD 20 cm/pixel digital flight from 14/02/2021 to 30/04/2022 (project 237) and a GSD GSD 8.4 cm/pixel digital flight made from 25/05/2020 to 07/05/2022 (project 234).
