A Technical Advisory Mission (TAM) serves to explore a Member State's capacity to fully take advantage of space-based information. As an inter-institutional fact-finding mission, it is officially requested by the respective national government and is carried out by a team of experts that UN-SPIDER gathers. Typically, TAMs are one-week long missions. The expert team meets with key disaster management and development authorities in the Government, United Nations organizations, regional and international organizations/initiatives and private entrepreneurs to discuss the use of space-based information for risk and disaster management in depth and to subsequently make recommendations on improvements.
