  • Os Ortofotomapas à escala 1:5 000 foram feitos a partir de um voo à escala 1:18 000. O voo foi executado durante o mês de Fevereiro de 2004. Só existem ortos acima da cota 600 metros. Abaixo desta cota foram produzidos ortos com escala 1:2 000. Para além dos ortos, foi também produzido um MDT (TIN, Curvas de Nível e Grid) com o mesmo voo.

  • The orthophotomaps at a scale of 1:5000 of Madeira Islands were made from a digital aerial survey with acquisition of digital photographs with a resolution of 30 cm. The flights were performed between July and September 2010 in three missions.

  • The orthophotomaps at a scale of 1:5000 of Desertas Islands were made from a digital aerial survey with acquisition of digital photographs with a resolution of 30 cm. The flights were performed between July and September 2010 in three missions.

  • The orthophotomaps at a scale of 1:5000 of Selvagens Islands were made from an analog aerial survey performed in August 2006. In the 2009 Selvagens Islands campaign triangulation stations were used, coordinated by the Hydrographic Institute in WGS84, for GGPS, having been reduced to ITRF2005 (GRS80), by the Faculty of Sciences of the University of Lisbon. The calculation of estimated positions was carried out based on a global network of about 200 stations (mostly IGS).
