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. An example of a tiling identification system is the Worldwide Reference System (WRS) where the surface of the Earth is split up 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 several 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 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

Coordinate 1/ Minimum Value: Identifies the minimum

value for one dimention

Examples:

"Hurricane Katrina"

"Mineral Resources"

"BEDI"

"Modified SAVI"

"Discrete-Band Normalized Difference Water Index"

"Principal Component Analysis"

"Hydrology"

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

Coordinate2/MinimumValue: 1

Coordinate2/MaximumValue: 80

TilingIdentificationSystemName: MODIS Tile SIN

Coordinate1/MinimumValue: 0

Coordinate2/MaximumValue: 35

Coordinate2/MinimumValue: 0

Coordinate2/MaximumValue: 17

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).

ARC Priority Matrix

Justification
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 data set
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) ancillary keyword contains a spelling errorThe element is being used incorrectly
This element is categorized as medium priority when: A recommendation is made to change an existing keyword The ancillary keyword is unnecessarily long The keyword doesn't seem appropriate or in any way related to the data set	N/A	add a tiling identification system to the metadata when appropriate
The element is provided, and follows all applicable criteria specified in the best practices section above.
