6 Environment and Climate Change 2008 To respond to the growing demand for Earth observation data, we will accelerate efforts within the Global Earth Observation System of Systems (GEOSS), which builds on the work of UN specialized agencies and programs, in priority areas, inter alia, climate change and water resources management, by strengthening observation, prediction and data sharing. We also support capacity building for developing countries in earth observations and promote interoperability and linkage with other partners.

7 … to answer Societys need for informed decision making Coordinate and Sustain Observation Systems Provide Easier & More Open Data Access Foster Use through Science, Applications and Capacity Building GEOSS - Global Earth Observation System of Systems…

9 Represents a COLOSSAL investment by GEO Members & PO in EO systems Delivers major societal benefits to USERS, such as policy makers & citizens Enables GEOSS resources to be readily discovered and accessed Appropriate interoperability Trusted (QA) data & information "Open, in accordance with DSP ( )

11 Highest Ranked Observations (#1-20) and Associated SBAs All of the 20 Highest- Ranked observations are common to 4 or more SBAs All of 30 Highest-Ranked observations are common to 3 or more SBAs * Biodiversity SBA Team did not produce a set of Earth observations priorities.

12 Global Land Cover maps in GEOSS FAO IGBP US(Boston Univ) The land cover maps does not suit mutually. Giri, C., Zhu, Z., and Reed, B., 2005. A comparative analysis of the Global Land Cover 2000 and MODIS land cover data sets, Remote Sensing of Environment 94, pp.123-132 McCallum, I., Obersteiner, M., Nilsson, S., and Shvidenko, A., 2006. A spatial comparison of four satellite derived 1 km global land cover datasets, International Journal of Applied Earth Observation and Geoinformation Which one is the best?

13 But, who does the ground-truth all over the world? I want to validate land cover maps For that purpose, Ground-Truth on a global scale, numerous, and spatially balanced validation data is needed

14 Degree Confluenc e Project Informati on might be useful! Degree Confluence Project

15 6000

16 What is Degree Confluence Project? The example of DCP EastSouth West North Courtesy DCP -visit the DCPoints (intersections of integer level latitude and longitude grid lines) -collect onsite data (photo and text base descriptions) from all the Degree Confluences in the world. - volunteer-based project
