6. Collect Earth user cases
Collect Earth facilitates the analysis of
high and very high resolution satellite
imagery for a wide variety of purposes,
including :
• Monitoring agricultural land
and urban areas
• Collection of spatially explicit
socio-economic data (Vietnam)
• Quantifying deforestation,
reforestation and desertification
(UN-REDD FREL )
• Support multi-phase National
Forest Inventories
• Land Use, Land Use Change
and Forestry (LULUCF)
assessments (18 partnering
countries)

7. Data Analysis - Saiku
• Fast, intuitive and flexible data analysis
• Powerful tool for data quality control
• Data export to Excel, CSV and PDF
• Produce colorful and informative charts and graphs with a few
clicks
• Export graphics to JPG, PNG or other formats

17. FAO Google Partnership

18. Earth Map – new FAO Google Tool
Google Earth Engine interface for simplified access to
complex datasets
Facilitated understanding of land cover/use dynamics
processes for:
● Design and baseline assessment
● Monitoring during implementation
● Final evaluation
Earth Map: new tool for quick historical environmental and
climate analysis

19. Code Editor full throttle and
basic users
Pros
Full power to the user +
Whole dataset access =
Huge potential
Cons
Blinking-cursor syndrome
Advanced skills requested
Unfit for most non-expert users
Also the Explorer may be too advanced in some context

20. Bare-bones interface, drop-down menus
Pre-set functions and data for areas/tasks
Google Infrastructure + FAO know-how
High local knowledge, mixed skills
AOI: pre-set or hand-drawn
Visual output as images, charts or tables
Trace anomalies and frequencies
Gather quantifiable evidence
Earth Map: facilitating, empowering,
leveraging users
