WMS Integrated Topographic Map. Year 2020-2021

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. Scope: El Hierro and Lanzarote Date of data: The Iron: cartography obtained from a low flight (GSD 8.4 cm/pixel), made from 26/05/2020 to 10/02/2021 and a high flight (GSD 20 cm/pixel), made from 26/08/2021 to 18/10/2021. Lanzarote: cartography obtained from a low flight (GSD 8.4 cm/pixel), made from 27/05/2020 to 15/02/2021 and a high flight (GSD 20 cm/pixel), made from 03/09/2021-17/10/2021.
