  1. GloboLakes Global Observatory of Lake Responses to Environmental Change • LIMNADES • GloboLakes Advisory Board Meeting, 15 January 2014 • Evangelos Spyrakos, Peter Hunter and Andrew Tyler • University of Stirling, UK Lake bio-optica​l Measurements and matchup Data for Remote Sensing http://www.globolakes.ac.uk/limnades

  2. LIMNADES Privately shared Publicly-user shared Lake bio-optica​l Measurements and matchup Data for Remote Sensing Global Observatory of Lake Responses to Environmental Change • LIMNADES provides a repository for: • inherent and apparent optical properties • in situ water constituent measurements http://www.globolakes.ac.uk/limnades http://www.globolakes.ac.uk

  3. LIMNADES Hosted data:

  4. LIMNADES • 14 responses during the first month of existence on GloboLakes web-page • Currently, data for 110 lakes, from 20countries on 5 continents (Asia, Africa, N. America, S. America & Europe) GLaSS CoW SAFER GloboLakes DIVERSITY II

  5. LIMNADES

  6. LIMNADES Composition of contributors Composition of data Inherent Optical Properties measurements? biogeochemical measurements? radiometric quantities radiometric quantities?

  7. What are the challenges associated with LIMNADES? • acquisition and preparation of data, metadata, documentation. • missing or incorrect documentation (metadata) • labor intensive • variety of digital formats and structures • range of attributes

  8. LIMNADES: development • Global demand for the repository has led to a subsequent NERC International Opportunities Fund Application (pending) to develop the database Aims: • 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

  9. LIMNADES: development Basic web service Ontology Advanced search interface Final advanced site

LIMNADES: tools • Web Server • Apache Tomcat, open source • Database Management Systems (DBMS) • PostgreSQL • Dynamic ontology development • MongoDB, Cassandra • Statistical Packages • Aggregate, graph • Programming Languages • C++, JAVAScript, Python, Visual Basic • Create Custom code • Visualization tools - jOWL

  12. LIMNADES: data access & policy • 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.
