An API expresses a software component in terms of its operations, inputs, outputs, and underlying types, defining functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising the interface. A good API makes it easier to develop a program by providing all the building blocks, which are then put together by the programmer. An API may be for a web-based system, operating system, or database system, and it provides facilities to develop applications for that system using a given programming language." As examples in EOSDIS, NASA's Common Metadata Repository (CMR) and Global Imagery Services (GIBS) provide an APIs to support client developers. ### Notes ### Examples ### Sources - NESDIS Data Management Lexicon and Related Terms ___ ## 2 Definition A set of functions and procedures allowing the creation of applications that access the features or data of an operating system, application, or other service. ### Notes An application programming interface (API) is an interface that defines interactions between multiple software applications or mixed hardware-software intermediaries. It defines the kinds of calls or requests that can be made, how to make them, the data formats that should be used, the conventions to follow, etc. It can also provide extension mechanisms so that users can extend existing functionality in various ways and to varying degrees. An API can be entirely custom, specific to a component, or designed based on an industry-standard to ensure interoperability. Through information hiding, APIs enable modular programming, allowing users to use the interface independently of the implementation. ### Examples ### Sources - CEOS CalVal Portal --- # Appraisal URL: https://ceos-org.github.io/eo-glossary/terms/appraisal Tags: core, to be discussed, calval ingest, WGISS, WGCV Summary: Procedure for assessing the value and suitability of Earth observation space data sets for long-term preservation. # Appraisal ## 1 Definition Procedure for assessing the value and suitability of Earth observation space data sets for long-term preservation. ### Notes ### Examples ### Sources - [CEOS/WGISS/DSIG/GLOS](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) --- # Archival Information Package URL: https://ceos-org.github.io/eo-glossary/terms/archival_information_package Tags: core, to be discussed, calval ingest, WGISS, WGCV Summary: Information package containing content and preservation description information preserved within an OAIS. # Archival Information Package **Synonyms**: AIP ## 1 Definition Information package containing content and preservation description information preserved within an OAIS. ### Notes An Information Package, consisting of the Content Information and the associated Preservation Description Information (PDI), which is preserved within an OAIS. ### Examples ### Sources - [CEOS/WGISS/DSIG/GLOS](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) - [Reference Model for an Open Archival Information System (OAIS), Recommended Practice CCSDS 650.0-M-2, Magenta Book 2012](https://public.ccsds.org/pubs/650x0m2.pdf) - NESDIS Data Management Lexicon and Related Terms --- # Archive URL: https://ceos-org.github.io/eo-glossary/terms/archive Tags: core, to be approved, calval ingest, WGISS, WGCV Summary: System for long-term storage of data products with guaranteed preservation. # Archive ## 1 Definition System for long-term storage of data products with guaranteed preservation. ### Notes - This function includes all operations to identify, store and retrieve the data and ensure their integrity. ### Examples ### Sources - [EO Data Stewardship Glossary](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) - [CEOS/WGISS/DSIG/GLOS](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) - [Reference Model for an Open Archival Information System (OAIS), Recommended Practice CCSDS 650.0-M-2, Magenta Book 2012](https://public.ccsds.org/pubs/650x0m2.pdf) ;

This type of request would likely always involve the transfer of data from Glacier to S3/EFS. ### Examples ### Sources - OSGS/CLASS - NCEI/DAB - NESDIS Data Management Lexicon and Related Terms --- # Business Continuity URL: https://ceos-org.github.io/eo-glossary/terms/business_continuity Tags: core, to be approved Summary: An organisation's readiness to continue functioning during times of disruption. # Business Continuity ## 1 Definition An organisation's readiness to continue functioning during times of disruption. ### Notes ### Examples ### Sources - [WGISS Shared Collection Lifecycle Management Principles for Earth Observation Data](https://ceos.org/document_management/Working_Groups/WGISS/Documents/Shared%20Collection%20Lifecycle%20Management%20Principles%20for%20Earth%20Observation%20Data_March2025.pdf) --- # Calibration URL: https://ceos-org.github.io/eo-glossary/terms/calibration Tags: core, source missing, to be discussed, calval ingest, WGISS, WGCV Summary: Process of quantitatively defining a system's response to known, controlled inputs using reference measurements. # Calibration ## 1 Definition Process of quantitatively defining a system's response to known, controlled inputs using reference measurements. ### Notes ### Examples ### Sources ___ ## 2 Definition Operation that establishes and applies a relation between measurement standard values and instrument indications to derive measurement results. ### Notes ### Examples ### Sources - (1) CEOS/ISO:19159 [RD10]: ISO/TS 19159-1:2014(en), Geographic information - Calibration and validation of remote sensing imagery sensors and data — Part 1: Optical sensors - (2) VIM/ISO:99 [ [RD18](https://www.bipm.org/en/publications/guides/vim.html) ] --- # Calibration Data URL: https://ceos-org.github.io/eo-glossary/terms/calibration_data Tags: core, to be discussed, calval ingest, WGISS, WGCV Summary: Data required to calibrate instrument science data, engineering data, and spacecraft data, including pre-flight and in-flight measurements, calibration coefficients, and ground truth. # Calibration Data **Synonyms**: CAL/VAL Data ## 1 Definition Data required to calibrate instrument science data, engineering data, and spacecraft data, including pre-flight and in-flight measurements, calibration coefficients, and ground truth. ### Notes CAL/VAL data can be considered as a digital data object (object composed of a set of bit sequences) part of a content information, related to other digital objects (i.e. primary data) through context information (the information that documents the relationships of the content information to its environment;

This approach helps align data citation and publication with the much more mature practices surrounding journal article publication. In this alignment, granules can be thought of as the words in that article. This functional definition allows for flexibility as well; just as current science domains have their own standards for what qualifies as a minimally citable body of work that can go into a single journal article, different data domains across NOAA can do the same and determine what makes sense to go into one of their collections. If NOAA should ever reach a more detailed definition, adjustments can be made to align the collection metadata with that new definition. ### Examples ### Sources - [CEOS/WGISS/DSIG/GLOS](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) -

Provisional Product was defined to facilitate data exploration and process studies that do not require rigorous validation. These data are partially validated and improvements are continuing; quality may not be optimal since validation and quality assurance are ongoing. Validated Products are high quality data that have been fully validated and quality checked, and that are deemed suitable for systematic studies such as climate change, as well as for shorter term, process studies. These are publication quality data with well-defined uncertainties, but they are also subject to continuing validation, quality assurance, and further improvements in subsequent versions. Users are expected to be familiar with quality summaries of all data before publication of results; when in doubt, contact the appropriate instrument team. - Stage 1 Validation: Product accuracy is estimated using a small number of independent measurements obtained from selected locations and time periods and ground-truth/field program efforts. - Stage 2 Validation: Product accuracy is estimated over a significant set of locations and time periods by comparison with reference in situ or other suitable reference data. Spatial and temporal consistency of the product and with similar products has been evaluated over globally representative locations and time periods. Results are published in the peer-reviewed literature. - Stage 3 Validation: Product accuracy has been assessed. Uncertainties in the product and its associated structure are well quantified from comparison with reference in situ or other suitable reference data. Uncertainties are characterized in a statistically robust way over multiple locations and time periods representing global conditions. Spatial and temporal consistency of the product and with similar products has been evaluated over globally representative locations and periods.

The term "time" instead of "duration" is often used in this context and also for an infinitesimal duration. - For the term "duration", expressions such as "time" or "time interval" are often used, but the term "time" is not recommended in this sense and the term "time interval" is deprecated in this sense to avoid confusion with the concept of "time interval". - The exact duration of a time scale unit depends on the time scale used. For example, the durations of a year, month, week, day, hour or minute may depend on when they occur (in a Gregorian calendar, a calendar month can have a duration of 28, 29, 30, or 31 days; in a 24-hour clock, a clock minute can have a duration of 59, 60, or 61 seconds, etc.). Therefore, the exact duration can only be evaluated if the exact duration of each is known. - This definition is closely related to NOTE 1 of the terminological entry "duration" in IEC 60050-113:2011, 113-01-13. ### Examples ### Sources - ISO 8601-1:2019, 3.1.1.8 --- # Dwell Time URL: https://ceos-org.github.io/eo-glossary/terms/dwell_time Tags: core, to be approved Summary: Time that an antenna beam spends on a target. # Dwell Time ## 1 Definition Time that an antenna beam spends on a target. ### Notes - In the context of radar sensing. ### Examples ### Sources - KCEO --- # Earth Observation URL: https://ceos-org.github.io/eo-glossary/terms/earth_observation Tags: high-impact, to be discussed Summary: Science domain dealing with technologies and methods of collecting and analyzing observations about the different Earth spheres. # Earth Observation ## 1 Definition Science domain dealing with technologies and methods of collecting and analyzing observations about the different Earth spheres. ### Notes - Earth Observation (EO) can be categorised by location of the sensor into space-borne, air-borne, sea-borne, ground-based, underwater and underground EO. - Earth Observation (EO) includes Remote Sensing, such as satellite imagery, as well as in-situ observations, e.g., with ground-based devices. ### Examples ### Sources - Modified GEO definition [GEO (earthobservations.org)](https://earthobservations.org/resources#key) --- # Earth Observation Based Output URL: https://ceos-org.github.io/eo-glossary/terms/earth_observation_based_output Tags: core, to be approved Summary: Higher-level processing and integration output (indicative level 4 and beyond) that goes beyond basic data processing. # Earth Observation Based Output ## 1 Definition Higher-level processing and integration output (indicative level 4 and beyond) that goes beyond basic data processing. These outputs are often designed specifically for policy or decision-making needs, and can be categorized into sub-categories: - Outputs from models/model integration: use of EO products as inputs in numerical models or combining them with other data sources in modelling frameworks. - Indicator-based outputs: EO products transformed through specialized algorithms (including statistical methods, machine learning, and pattern recognition) to create meaningful metrics based on spatio-temporal analysis. - Outputs from reanalysis: merging of EO products with other observations and models, creating consistent long-term records of past atmospheric, oceanic, and land surface conditions, and filling gaps through data assimilation techniques. ### Notes ### Examples ### Sources - KCEO --- # Earth Observation Product URL: https://ceos-org.github.io/eo-glossary/terms/earth_observation_product Tags: core, to be approved Summary: Direct output from standardized satellite data processing chains (indicative levels 2 and 3), representing fundamental geophysical and biophysical variables. # Earth Observation Product ## 1 Definition Direct output from standardized satellite data processing chains (indicative levels 2 and 3), representing fundamental geophysical and biophysical variables. These products demonstrate direct Traceability to original satellite measurements through rigorous Calibration and Validation processes.

Because routing services use internal Location encodings not usually available to others, a geocoder is an integral part of the internals of such a service. ### Examples ### Sources - ISO 19133:2005;

Specialized data APIs also support subsetting for order fulfillment (Common Access). In research communities (for example, [earth sciences](https://en.wikipedia.org/wiki/Earth_science) , [astronomy](https://en.wikipedia.org/wiki/Astronomy) , [business](https://en.wikipedia.org/wiki/Business) , and [government](https://en.wikipedia.org/wiki/Government) ), subsetting is the process of retrieving just the parts of large files which are of interest for a specific purpose. This occurs usually in a client—server setting, where the extraction of the parts of interest occurs on the server before the data is sent to the client over a network. The main purpose of subsetting is to save bandwidth on the network and storage space on the client computer. Subsetting may be favorable for the following reasons: [[1](https://en.wikipedia.org/wiki/Subsetting#cite_note-Institute2012-1) ] - restrict or divide the time range - select [cross sections](https://en.wikipedia.org/wiki/Cross-sectional_data) of data - select particular kinds of [time series](https://en.wikipedia.org/wiki/Time_series) - exclude particular observations Subsetting within Programs You can subset within statistical software programs to help speed up the process of subsetting if needed. There are many different types of subsetting that can provide challenges with using software programs though. Some types of subsetting are: - Atomic Vectors - Lists - Matrices and Arrays - Data Frames - S3 Objects - S4 Objects ### Examples ### Sources - [ECS Project](http://edhs1.gsfc.nasa.gov/waisdata/docsw/pdf/tp1520303.pdf) - [NCEI/DAB](https://calvalportal.ceos.org/web/guest/t-d_wiki?p_p_id=com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn&p_p_lifecycle=0&p_p_state=normal&p_p_mode=view&_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_mvcRenderCommandName=%2Fwiki%2Fedit_page&_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_redirect=https%3A%2F%2Fcalvalportal.ceos.org%2Fweb%2Fguest%2Ft-d_wiki%3Fp_p_id%3Dcom_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn%26p_p_lifecycle%3D0%26p_p_state%3Dnormal%26p_p_mode%3Dview%26_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_mvcRenderCommandName%3D%252Fwiki%252Fview_page%26_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_nodeName%3DCEOS_Terms_and_Definitions%26_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_title%3DSubsetting&_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_nodeId=668236&_com_liferay_wiki_web_portlet_WikiDisplayPortlet_INSTANCE_B9cyrDcwYNcn_title=NCEI%2FDAB) - NESDIS Data Management Lexicon and Related Terms --- # Swath URL: https://ceos-org.github.io/eo-glossary/terms/swath Tags: core, to be discussed, calval ingest, WGCV, WGClimate Summary: Area covered by spatial samples collected during a scan of a spaceborne instrument, determined by its incidence angle. # Swath ## 1 Definition Area covered by spatial samples collected during a scan of a spaceborne instrument, determined by its incidence angle. ### Notes ### Examples ### Sources - [CEOS/WGISS/DSIG/GLOS](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) - [CEOS EO Data Stewardship Glossary](https://ceos.org/document_management/Working_Groups/WGISS/Interest_Groups/Data_Stewardship/White_Papers/EO-DataStewardshipGlossary.pdf) - NESDIS Data Management Lexicon and Related Terms --- # System URL: https://ceos-org.github.io/eo-glossary/terms/system Tags: core, to be discussed, calval ingest, WGISS, WGCV Summary: Set of interrelated or interacting elements. # System ## 1 Definition Set of interrelated or interacting elements ### Notes ### Examples ### Sources - ISO:9000 [ [RD7](https://www.iso.org/standard/45481.html) ] --- # Systematic Error URL: https://ceos-org.github.io/eo-glossary/terms/systematic_error Tags: core, to be discussed, calval ingest, WGCV, WGISS Summary: Component of measurement error that remains constant or varies predictably across replicate measurements. # Systematic Error ## 1 Definition Component of measurement error that remains constant or varies predictably across replicate measurements. ### Notes ### Examples ### Sources - VIM/ISO:99 [ [RD18](https://www.bipm.org/en/publications/guides/vim.html) ] --- # Tagging URL: https://ceos-org.github.io/eo-glossary/terms/tagging Tags: core, to be discussed, calval ingest, WGISS, WGCV Summary: Process of adding tags or annotations to components of unstructured data at a granular level to prepare it for analysis, enabling deeper insight beyond broad categorization. # Tagging ## 1 Definition Process of adding tags or annotations to components of unstructured data at a granular level to prepare it for analysis, enabling deeper insight beyond broad categorization. ### Notes see metadata; Metadata tagging has traditionally been a manual and often laborious process.

Workflows occur across every kind of business and industry. Anytime data is passed between humans and/or systems, a workflow is created. Workflows are the paths that describe how something goes from being undone to done, or raw to processed. Workflows happen throughout the workspace. Some are very structured, and others are unstructured, but workflows exist anytime data moves from one task to another. ### Examples ### Sources - [1] [Cornell Center for Advanced Computing](https://www.cac.cornell.edu/education/training/StampedeJan2015/workflowsAndDataManagement.pdf) - NESDIS Data Management Lexicon and Related Terms
