Composition of data
biogeochemical measurements? radiometric quantities radiometric quantities?
Inherent Optical Properties measurements?
• acquisition and preparation of data, metadata, documentation.
• missing or incorrect documentation (metadata)
• labor intensive
• variety of digital formats and structures
• range of attributes
What are the challenges associated with LIMNADES?
LIMNADES: development
• Basic User account Management and document Up/Download
• Ontology based search, analysis and data assimilation
• Dynamic ontology development and data interpretation
• Data visualisation, Quality control & intelligent data capture
• Data discovery and assisted browsing
Aims:
• Global demand for the repository has led to a subsequent NERC International Opportunities Fund Application (pending) to develop the database
Basic web service
Ontology
Advanced search interface
Final advanced site

LIMNADES: tools
• 1. RESEARCH AND EDUCATION. The use of data held by LIMNADES is strictly limited to research and educational purposes. Commercial use of data is only permitted if explicitly indicated in the questionnaire.
• 2. DATA ACCESS. By agreeing to our data policy you consent to the use of the data within the GloboLakes project in accordance to LIMNADES data policy. Data providers have two additional options for sharing data. Eligible additional data users are all other LIMNADES data providers (hereafter referred to as ‘public’) and/or the ESA’s Diversity II project. Data that are not publicly available are accessible to other LIMNADES users but only through prior approval of the original data provider. Only LIMNADES data providers may request access to the data holdings.
• 3. FULL ACKNOWLEDGEMENT. LIMNADES users must fully acknowledge the use of LIMNADES data and the original data provider(s) in any publications arising from the use of the data.
• 4. CO-AUTHORSHIP. Data users should contact the original data provider for approval at an early stage where there is an intent to use their data in publications. Co-authorship is not required, but should be offered particularly where a publication draws heavily on data from one or more providers.
• 5. CORRECTIONS. Corrections of errors and update of the records by data authors are encouraged
