Ground Data Collection in South Africa's Natal Drakensberg Park, a UNESCO World Heritage site as well as Ramsar site.
In-situ data collection is a critical aspect of the project. The collaboration of the users in the field is a key element for the success; ground data is sued to calibrate and validate the final products. During 2004 it was carried out at sites in Kenya, South Africa, Austria, Canada, France, Greece, Spain, Portugal and Russia.
