The Tiling Identification System element defines a named two-dimensional tiling system related to the collection.
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 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 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 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
Providing a Tiling Identification System is optional. An unlimited amount of Tiling Identification Systems may be provided (Cardinality: 0..*)

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).
