AfriGEOSS: GEO activities in Africa
Objectives• Bring together relevant Earth observation stakeholdersBring together relevant Earth observation stakeholders,
institutions and agencies across Africa;• Provide a platform for countries to participate in GEO and to p p p
contribute to GEOSS;• Assist in knowledge sharing and global collaborations;g g g• Leverage existing capacities and planned assets and
resources• Identify challenges, gaps and opportunities for African
contributions to GEO and GEOSS;

Several producers• Several producers – Consensus: Model, strategy, road map, technical
standardsstandards
• Many users/applications• Many users/applications– Full global coverage with good quality of HR
imageryimagery– Validation of the GLC products– Continuous updating– Continuous updating
Lack of connection between users and providersLack of connection between users and providers
Recommendations for National Authorities
• Involvement in the assessment of their needs in GLC-related• Involvement in the assessment of their needs in GLC related products, tools and services,
• Contribute to the validation of the products developed andContribute to the validation of the products developed and • Participate in capacity building activities/ Participate in GEO
Benefit:Development of tools and products thatDevelopment of tools and products that • cover their needs taking into consideration their national
priorities andpriorities and • Are accessible through an “one stop shop”Development of in-country capacity for the use of these toolsDevelopment of in country capacity for the use of these toolsTake informed decisions and justify them
