This course aimed to open the minds of participants to the many facets of geo-data processing using information available on the Internet, focusing on Earth observation from space; developing practical experience in extracting information on natural resources management using on-line software collaborative techniques; understanding the complexity of resources evaluation and ways of mediating various conflicting management objectives and risks using multicriteria decision analysis. The course offered a clear understanding of the multidisciplinary issues involving the coupling between geo-imaging methods, the modeling of natural processes and the economic evaluation of resources.
