Service Interruption

The NSIDC Web site and data services are currently having intermittent problems and may be unavailable. We are working to restore these services as soon as possible and apologize for any inconvenience this may cause. Please contact NSIDC User Services for assistance.

Searchlight

NSIDC has changed our user access model from "Search and Order" and "Wait and Download" to "Discover and Access." We have enhanced the process for searching and receiving our data with our new infrastructure that supports users finding and browsing actual data holdings online.

Searchlight is a layered architecture built in Java with a PostGIS data base. It is a robust, extensible infrastructure that can be leveraged by applications to discover and access disparate data types with on-the-fly reprojection, regridding, and reformatting. It was efficiently developed by focusing on reusing open source software, following best practices, and implementing proven design patterns. It reuses many open source libraries and utilities to enable rich functionality. This functionality includes processing and outputting of multiple formats, subsetting, reprojection, free text search, and a Web 2.0 interface. Future reuse of Searchlight components are supported at varying levels, ranging from the database and model components to Web services.

The Searchlight architecture is flexible for future enhancements, maintainable for a long expected life span, and capable of scaling to meet future growth and additional services to meet the changing needs of our user community.

For questions about Searchlight, please contact NSIDC User Services.

Applications and Services Using Searchlight

 
Polaris
Polaris serves as a navigation point for limited NSIDC data sets adding subsetting, reformatting, and reprojecting capabilities.
SAGE
The Services for the Analysis for the Greenland Environment (SAGE) adds analysis capabilities and a unique interface for specific Greenland data sets. It is a tool designed to help scientists access, integrate, and analyze data related to the history and status of Greenland's ice sheet in real time using timeseries, scatterplot, histogram, and box and whisker plots. Currently SAGE supports seven data sets.
OpenSearch
Searchlight provides OpenSearch services for data set and granule level data discovery. Searchlight also provides data access and retrieval through REST services which can be accessed from OpenSearch results.
SubsetAgent/GetData
The SubsetAgent/GetData Application Programming Interface (API) provides a simple way to search and access NSIDC's data holdings that are hosted through Searchlight. It allows for the search and customization (subsetting, reprojection, and reformatting) of NSIDC data with immediate downloads.
