EOSDIS System Evolution ESDIS was directed to evolve the systems under its budget to accommodate vision identified by a joint EOSDIS Elements Study/Technical team Key vision elements include: –Improve access and processing services, ensure available expert knowledge, reduce operational costs, ensure safe stewardship, maintain IT currency

EOSDIS System Evolution Top 3 cost drivers contribute to approx. 50 % of total budget: –EMD/ECS –GES DAAC –LaRC DAAC Factors that contribute to top 3 cost drivers: –Operating multiple systems (ECS, V0/V1, LaTIS, etc.) –DAAC-unique capabilities and science community support beyond specific operation of ECS/SDPS –Providing sustaining engineering for ECS/SDPS at the four ECS DAACs

ESDIS Evolution Path Approval has been given to embark down an evolution path GES DAAC and ASDC DAAC to evolve away from ECS SDPS at their sites MODAPS to evolve towards archive and distribution of all MODIS products ECS SDPS footprint to be reduced greatly in terms of hardware and custom code Summary of the plan can be found at

EOSDIS Today EOSDIS provides –A production capability for standard science data products from EOS instruments –An “active archive” of Earth science data from EOS and other past and present missions –A distributed information framework (data centers, SIPS, networks, interoperability, other system elements) with partners supporting EOS investigators and other users in science, government, industry, education, and policy EOSDIS_Today_ xls

EOSDIS 2006 Customer Satisfaction Survey EOSDIS’ third survey, about 2800 responders Survey has changed slightly each time, but the standard questions for measuring satisfaction are the same 2006 survey addressed product search, selection and order, distribution, quality, documentation and customer support

Respondent Background Q8. For which disciplines do you need or use Earth science data? (n=2,857)*

Customer Survey Product Quality

Summary of HDF-related comments to the CFI Survey (Informally assessed) Need tools for data handling 20 More useful for various user types (GIS/educational/science) if in some other than HDF format. 19 Make the distribution format fit what the user wants (or at least add more flexibility) 14 Would prefer NetCDF 8 Need to pay attention to usability of data products 3 Need documentation to extract from HDF-EOS (or HDF) file 2 Need program to extract or convert HDF-EOS Data 2 Hard for nonprogrammers to handle HDF 1 HDF-EOS is a bad format for multi-spectral/multi-angle data sets 1 Need windows tool for HDF 1 No response to help 1 We read HDF-EOS data as HDF5 1

How May We Help You? The data gleaned from the survey leads us to conclude that the ESDIS Project needs to examine solutions for the areas of: –Data handling support software –Preprocessed/flexibly-formatted data access paths –NetCDF –GeoTIFF when applicable
