Element Description

The type of the service being described. These types of services are back-end service types. 

Best Practices

Curators must use the controlled list for the type of service. 

• OPeNDAP: A type of service that enables researchers to access and share NASA Earth science data from a wide variety of programs. For more information, see https://www.earthdata.nasa.gov/engage/open-data-services-and-software/api/opendap. 
• THREDDS: A type of service that provides researchers with access to a large collection of real-time and archived dataset from a variety of environmental data sources at a number of distributed server sites. For more information, see https://www.unidata.ucar.edu/software/tds/. 
• WEB SERVICES: A type of interoperable machine-to-machine software function that is hosted at a network addressable location. A web service has an interface that hides the implementation details so that it can be used independently of the hardware or software platform on which it is implemented and independently of the programming language in which it is written. For more information, see https://www.earthdata.nasa.gov/technology/web-services.  
• ESI: A EOSDIS service interface (ESI) web-service that runs on an internal host (i.e. only accessible on the DAAC internal network). Its primary functionality is to route service requests to subagents, but also includes a test-support inventory access ("drill-down") and service access capability, including the ability to generate echo forms. For more information, see 4.8.21.1.1 EOSDIS Service Interface (ESI) EED3-609 Release 22.1
• ECHO ORDERS: A type of service that enables the delivery of data via CMR legacy services. 
• WCS: A web coverage service that offers multi-dimensional coverage data for access over the Internet. For more information, see https://www.ogc.org/standards/wcs. 
• WMS: A web map service that providers a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. For more information, see https://www.ogc.org/standards/wms. 
• WMTS: A web map tile service that offers a standard protocol for serving pre-rendered or run-time computed georeferenced map tiles over the Internet. For more information, see https://www.ogc.org/standards/wmts. 
• EGI - No Processing: 
• SOFTWARE PACKAGE: An assemblage of files and information about those files. For more information, see https://en.wikipedia.org/wiki/Software_package. 
• TOOL: A desktop application which must be downloaded to the user’s processing platform in order to use them. For more information, see EOSDIS Tools and Services Portfolio Home. 
• WEB PORTAL: A web-based platform that collects information from different sources into a single user interface and presents users with the most relevant information for their context. For more information, see https://www.liferay.com/resources/l/web-portal. 
• International Web Portal: An internationally focused web-based platform that collects information from different sources into a single user interface and presents users with the most relevant information for their context. For more information, see https://www.liferay.com/resources/l/web-portal.
