Element Description

Note: This wiki page is a draft/ work in progress

The Tiling Identification System element defines a named two-dimensional tiling system related to the collection.

Best Practices

A tiling identification system is a defined 2-D grid which covers the surface of the Earth. Each segment of the grid, or tile, should have a name or numerical designation. Tiling identification systems can be used to categorize data by location in a data catalog, and can often be used as a search parameter when searching for data. An example of a tiling identification system is

This element should only be used for established tiling identification systems and should not contain ad hoc names not defined anywhere outside of the metadata.

The Ancillary Keywords element is optional, and is an uncontrolled free-text field. It can be leveraged to provide any additional keywords needed to describe the collection in addition to the Science Keywords (which

An example of a tiling identification system is the Worldwide Reference System (WRS) where the surface of the Earth is split into numbered paths and rows. The WRS-2 system is used to catalog Landsat data and is a popular way to search for Landsat data. Another example are the various MODIS grids, such as the MODIS Sinusoidal Tile Grid system which divides the Earth into 595 10 x 10 degree tiles.

There are five sub-elements used to specify a tiling identification system. If provided, all of the sub-fields are required:

Tiling Identification System Name: This field identifies the name of the tiling identification system. The name must be selected from a controlled

vocabulary list). This can be useful for providing tags needed for other applications or for providing niche keywords which may not fit in the current scope of the controlled science keyword vocabulary. Ancillary keywords are indexed for search using the CMR API, however, they do not appear as faceted keywords in the Earthdata Search Client user interface.

enumeration list which includes the following values: CALIPSO, MISR, MODIS Tile EASE, MODIS Tile SIN, WELD Alaska Tile, WELD CONUS Tile, WRS-1, WRS-2, Military Grid Reference System

Coordinate 1/ Minimum Value: Identifies the minimum value for one dimension (e.g. horizontal) of the two dimensional tiling system.

Coordinate 1/ Maximum Value: Identifies the maximum value for one dimension (e.g. horizontal) of the two dimensional tiling system.

Coordinate 2/ Minimum Value: Identifies the minimum value for the other dimension (e.g. vertical) of the two dimensional tiling system.

Coordinate 2/ Maximum Value: Identifies the maximum value for the other dimension (e.g. vertical) of the two dimensional tiling system.

Examples:

TilingIdentificationSystemName: MISR

Coordinate1/MinimumValue: 1

Coordinate2/MaximumValue: 233

Metadata Validation and QA/QC

All metadata entering the CMR goes through the below process to ensure metadata quality requirements are met. All records undergo CMR validation before entering the system. The process of QA/QC is slightly different for NASA and non-NASA data providers. Non-NASA providers include interagency and international data providers and are referred to as the International Directory Network (IDN).

Priority Categorization	Justification
Red = High Priority Finding	This element is categorized as highest priority when: The Tiling Identification System Name does not match an enumeration value (CALIPSO, MISR, MODIS Tile EASE, MODIS Tile SIN, WELD Alaska Tile, WELD CONUS Tile, WRS-1, WRS-2). The Tiling Identification System provided is incorrect for the dataset.
Yellow = Medium Priority Finding	This element is categorized as medium priority when: The Tiling Identification System Name does not match an enumeration value when the metadata format is anything other than UMM-JSON (this field is not controlled in other metadata dialects).
Blue = Low Priority Finding	This element is categorized as low priority when: A recommendation is made to add a tiling identification system to the metadata when appropriate.
Green = No Findings/Issues	The element is provided, and follows all applicable criteria specified in the best practices section above.
