ESA-IMoD Advanced SAR Workshop – ESRIN, 9-20 November 2015
‘Open Initiative on the Use of Space Technologies to Support the World Heritage Convention’
http://www.unesco.org/science/remotesensing/?id_page=135&lang=en
On 18 June 2003 at the Paris Air Show in Le Bourget (France), UNESCO and the European Space Agency (ESA) signed an agreement to encourage Earth observation satellites to be used to monitor cultural and natural World Heritage sites. The signing of the Agreement officially launched the ‘Open Initiative on the Use of Space Technologies to Support the World Heritage Convention’. It aims to develop a framework of co-operation in order to assist developing countries, through space technologies, to improve their natural and cultural conservation activities

Training and Capacity Building in Remote Sensing applications to Cultural Heritage (CH)
Recent relevant training courses:
• EARSeL courses related to archeological remote sensing held in the framework of EARSeL workshops
– 2012, Gent, Belgium, on the occasion of 3rd EARSeL CH workshop – 2013, Matera, Italy, on the occasion of 4th EARSeL CH workshop
• SAR training course in Malta, Nov 2014 • Remote Sensing for Archaeological Applications in Argentina, training
through videoconference, 2014 • 3rd ESA-EARSeL course on remote sensing for archaeology, ESRIN 9-11
Nov 2015 (just concluded) with focus on the use of SAR intensity for palaeolandscape mapping and InSAR for the monitoring of the structural integrity of archaeological sites
