Improving Data Access, Discovery, and Usability Amanda Leon - Deputy DAAC Manager Renea Ericson - DAAC Software Project Lead

Current DAAC efforts to improve: DISCOVERY ACCESS Programmatic access to services Worldview/GIBS Polar Map Application AppEEARS On-demand services USAGE

Imagery exploration in NASA Worldview/GIBS Visual data exploration benefits a range of users The DAAC and SIPS are producing GIBS imagery for targeted data Available now: MODIS 500 m Snow | SMAP | MEaSUREs Freeze/Thaw Available by end of FY16: SSM/I-SSMIS TBs & Sea Ice | MEaSUREs Greenland & Antarctic Ice Sheet, NH State of Cryo | Aquarius Soil Moisture Future: MODIS ? | ICESat-2 | Others? “Visualize” button takes users to preloaded imagery and date in Worldview Overlay and compare hundreds of NASA data layers Download a GeoTIFF or native data files

On-demand data services Addresses main data challenges and use cases cited by our user communities Heterogeneous data formats and projections Specific parameters or regions of interest Data volumes Establishing a service baseline for our high level-of-service, EOSDIS products Current: AMSR | ICESat | MODIS | SMAP | SSM/I-SSMIS Planned: AMSR-U | ICESat-2 | MeASUREs | VIIRS Requires an extensible, sustainable architecture Leverage technologies (gdal, OPenDAP) to efficiently extend to new data Scalable processes for testing and maintaining Subset Parameter Spatial Temporal Reformat Reproject GeoTIFF NetCDF ASCII HDF KML UTM Geographic Polar stereo EASE

Programmatic access to data services Access to on-demand services has been through a user interface (Reverb, Earthdata Search) Offering programmatic (machine-to-machine) access will allow expert users to integrate them into their data workflows Identified as key ICESat-2 user need Will expose OPeNDAP API with instructions for accessing with common applications (Matlab, Panoply) Working with ESDIS and EED on a standards-based (WCS) API access to the suite of existing on-demand services

Polar Map Application Integrated tile caching Replaces desired functionality of Atlas of The Cryosphere (EOL) Including key polar-focused data layers Sea Ice Extent |Sea Ice concentration |GLIMS Glacier Outlines Using relevant imagery layers from GIBS Coastlines | Graticule | Blue Marble Technology can be leveraged for other domain-focused map applications (e.g. snow, soil moisture) Uses GeoServer Integrated tile caching Robust support of OGC protocols Maturity – Large user base, active internet community

Polar Map Application Progress to-Date Next Step Ingest utility Currently command line Functional with raster and vector data Can be leveraged by other project GeoServer REST interface Admin GUI Next Step Complete user Interface Evaluate other datasets for incorporation into Polar Map Application (PMA) Leverage PMA to replace functionality of other NSIDC tools

AppEEARS – LP and NSIDC DAAC Collaboration Application for Extracting and Exploring Analysis Ready Samples Developed at LP DAAC Provides aggregated time series at a point; will be extended to polygons Current NSIDC subsetting services do not aggregate into single file Data aggregation using OPeNDAP

AppEEARS – LP and NSIDC DAAC Collaboration Progress to-Date NSIDC used LPDAAC code to create prototype Ingested MODIS MOD10A1 data Successful testing LP & NSIDC DAACs have found and addressed some collaboration issues Planning next phase Phase 2 Build Operational Server Ingest, test and operationalize all MODIS snow data Development starts late August Target for operational functionality 12/2016 Potential next use cases - SMAP
