Overview
• Opportunity: The increased number of satellites provide a dense time series to
improve change detection and classification of global forest cover
• Problems and options:
– Higher data volume increases processing, storage and delivery costs
• Process data in cloud, for example on Google or Amazon, or at partner, for example FAO, – download
information products
• Access to faster internet, faster processing and more storage at national agencies
• Tools to maintain local databases through incremental updates
• Requirement refinement, discovery and selection tools to limit data data downloaded to data required
– Multiple sensors increase the importance of georegistered, cross-calibrated, surface
reflectance, and reformatted Analysis Ready Data
• Analysis Ready Data created at space agency or with partner to reduce the burden at national agencies
– Additional choices adds complexity to data discover and selection
• Tightly define requirements and only acquire minimal subset of data
– New methodologies are needed to benefit from more data
• Work with space agencies and partners to evaluate and implement new methodologies

Global Forest Observation Scenarios
• Business-as-usual Scenario
–
–
–
–
Uncoordinated delivery usually on media of data or limited access through the Internet
Few tools or methodologies for updating and maintaining structured ARD time series
Limited infrastructure for long term monitoring program
Forest products are created at national agencies
• Scenario-1: Delivery of space data to a commercial cloud or data hub for
country agency access and analysis
– Forest Products are created at external location over the Internet by national agency staff
– Costs are concentrated in data storage and processing in the cloud or at partner agencies
– Forest Products are downloaded from the cloud or data hub
• Scenario-2: Delivery of space data and tools to a country agency
– Images are download and image archives are managed at national agencies using CEOS and
other tools
– Costs are concentrated in data transmission, storage and processing at national agencies
– Forest products are created at national agencies

Evaluation Criteria
• Objective: Position countries to establish operational
Measurement, Reporting and Verification methodologies within
National Forest Monitoring Systems in the next 15 years.
• Criteria:
–
–

–
–
–
Operational solution?
Opportunities for growth?
Inclusion of other sensors beyond Landsat and Sentinel-2 optical sensors?
Support collaborative relationships among nations and with partners?
Sustainable?
Reliable?
Implementable – maturity, setup costs, maintenance costs?
• Leading to Evaluation and Recommendations
– Prototype will be implemented for Kenya
– Solutions must be generally applicable
