Resolution of Satellite Data Exchange Principles in Support of Global Change Research (Draft) 18 May 1993
- Recognizing that the members of CEOS are actively involved in supporting
global change/climate and environmental research and monitoring efforts
of the international scientific community, as well as pursuing other uses
of Earth observations data such as local/regional research, operational
environmental monitoring, and commercial;
RECOGNIZING THE INVESTMENTS MADE BY GOVERNMENTS AND INTERNATIONAL AGENCIES IN SUPPORT OF GLOBAL CHANGE/CLIMATE RESEARCH AND ENVIRONMENTAL RESEARCH AND MONITORING AND THE VALUE OF NON-SATELLITE DATA TO THESE PROGRAMS;
TAKING INTO ACCOUNT THAT THE ACQUISITION, PROCESSING, AND SUPPLY OF
DATA, ESPECIALLY SPACE DATA, INVOLVE MAJOR INVESTMENTS, AND THAT DATA HAVE
VALUE;
RECOGNIZING THAT THESE INVESTMENTS AND VALUES SHOULD BE RESPECTED BY
DATA SUPPLIERS AND USERS;
RECOGNIZING THE EXISTENCE OF VARIOUS POLICY AIMS SUCH AS MAXIMIZING THE USE OF THE DATA FROM ALL SOURCES AND SHIFTING THE FUNDING RESPONSIBILITY FOR CERTAIN REMOTE SENSING SYSTEMS TO USERS OR OTHER SOURCES;
Aware that success in global change/climate and environmental research and monitoring requires a continuing commitment to the establishment, maintenance, validation, description, accessibility, and distribution of highquality long-term data sets, many of which rely on space borne observations;
Anticipating the potential benefits of compatible policies and mechanisms for data exchange in obtaining access to global dara;
REAFFIRMING THE COMMITMENT OF CEOS MEMBERS TO THE GENERAL PRINCIPLE
OF NONDISCRIMINATORY ACCESS TO DATA;
RECOGNIZING THE IMPORTANCE OF APPROPRIATE LEGAL REGINES FOR THE EXCHANGE
OF REMOTELY SENSED DATA;
RECOGNIZING THE IMPORTANCE OF APPROPRIATE LEGAL REGIMES FOR THE EXCHANGE OF REMOTELY SENSED DATA;
RECOGNIZING THE COMMON GOAL OF PROVIDING DATA TO GLOBAL CHANGE RESEARCHERS FROM ALL MISSIONS ON A CONSISTENT BASIS REFLECTING PRIMARILY THE COST OF FILLING THE USER REQUEST; RECOGNIZING ALSO THAT THE CONSTRAINTS OF THE MISSION OPERATIONS AND OF AVAILABLE RESOURCES MAY REQUIRE DIFFERENT MECHANISMS FOR DATA EXCHANGE/SHARING TO BE FOUND FOR DIFFERENT PROGRAMS;
CEOS members endorse the following pricnciles relating to SATELLITE data exchange in support of global change/climate and environmental research and monitoring and agree to work toward implementing them to the fullest extent possible. Principles for data exchange in support of other data uses beyond global change/climate and environmental research and monitoring will be developed for CEOS endorsement as a next step.
1. Preservation of all data needed for long-term global change/climate and environmental research and monitoring is required.
2. Data archives should include easily accessible information about the data holdings, including quality assessments, supporting ancillary information, and guidance and aids for locating and obtaining the data.
3. International standards, including those generated by the CEOS Working Group on Data, should be used to the greatest extent possible fo recording/storage media and for processing and communication of data sets.
4. Maximizing the use of satellite data is a fundamental objective. An exchange/sharing mechanism among CEOS members is an essential first step to maximize use.
5. NONDISCRIMINATORY ACCESS TO SATELLITE DATA BY ALL USERS FOR GLOBAL CHANGE/CLIMATE AND ENVIRONMENTAL RESEARCH AND MONITORING IS ESSENTIAL. THIS SHOULD BE ACHIEVED WITHIN THE FRAMEWORK OF THE EXCHANGE AND SHARING MECHANISMS SET UP BY CEOS MEMBERS.
6. Programs should have no exclusivee period of data use. Where the need to provide validated data is recognized, any initial period of exclusive data use should be limited and explicitly defined. The goal should be release of data in some preliminary form within 3 months after the start of reoutine data acquisition.
7. Criteria and priorities for data acquisition, archiving, and purging should be harmonized. (Changes since the last plenary in capital letters.)
