Real benefits of Geoinformatics
• More usage of model results for science• More feedback to modelers
=> Improved models• More efficient retrieval of data
=> More time to do science
Opportunities for modelers (1/2)
• Join the IOOS Model Data Interoperability Google Group: http://groups.google.com/group/ioos_model_data_interop
• Join the Unstructured Grid Interoperability Google Group: http://groups.google.com/group/ugrid-interoperability
Opportunities for modelers (2/2)
• Try out the Matlab NCTOOLBOX to access CF-compliant model output:http://code.google.com/p/nctoolbox
• Give us feedback! Suggest more functionality! Toolbox is under active development
