WMS Integrated Topographic Map. Year 2016

The 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 22.5 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: Gran Canaria and La Palma Date of data: Gran Canaria: cartography obtained from a low flight (217, GSD 8.4 cm/pixel), made from 13/03/2016 to 17/04/2016 and a high flight (216, GSD 22.5 cm/pixel), made from 10/04/2016 to 03/06/2016. La Palma: cartography obtained from a low flight (217, GSD 8.4 cm/pixel), made from 07/09/2016 to 08/09/2016 and a high flight (216, GSD 22.5 cm/pixel), made from 02/06/2016 to 07/06/2016.
