Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
NASA’s Earth Observing System Data and Information System (EOSDIS) is evolving to expose data using standards based geospatial web services, e.g. Web Coverage Service (WCS), Web Mapping Service (WMS). There is a need for fusion of services with existing data systems, and integration with new systems such as NASA’s Cumulus, which will be a cloud-based source of NASA data.
