There are many definitions of GSD. The value of this field should be related to the spatial resolution at the sensor, rather than the pixel size of images after orthorectification, pansharpening, or scaling. The GSD of a sensor can vary depending on geometry (off-nadir / grazing angle) and wavelength, so it is at the discretion of the implementer to decide which value most accurately represents the GSD. For example, Landsat8 optical and short-wave IR bands are all 30 meters, but the panchromatic band is 15 meters.

| instrumentShortName | StringAttribute | yes | STAC core attribute | instruments | mandatory | mandatory | na | Can be array of strings. | name of the Instrument | An array of all the sensors used in the creation of the data. For example, data from the Landsat-8 platform is collected with the OLI sensor as well as the TIRS sensor, but the data is distributed together so would be specified as ['oli', 'tirs'] | List of the instruments providing the acquisitions used for producing the product. This is used to search and filter on instrument. If multiple values, use comma seperator without whitespace. | VEGETATION | VEGETATION | |
| metricGridSpacing | IntegerAttribute | yes | STAC core attribute | gsd | mandatory | mandatory | na | CLMS specific | The nominal Ground Sample Distance for the data, as measured in meters on the ground. There are many definitions of GSD. The value of this field should be related to the spatial resolution at the sensor, rather than the pixel size of images after orthorectification, pansharpening, or scaling. The GSD of a sensor can vary depending on geometry (off-nadir / grazing angle) and wavelength, so it is at the discretion of the implementer to decide which value most accurately represents the GSD. For example, Landsat8 optical and short-wave IR bands are all 30 meters, but the panchromatic band is 15 meters. The gsd should be 30 meters in this case because that is the nominal spatial resolution at the sensor. | Refers to the nominal grid spacing of the product, expressed in meters. The purpose of this additional field is to filter on the nominal grid spacing as a number eg. metricGridSpacing > 300. | 1000 | 1000 | ||

| Name | StringAttribute | yes | STAC core attribute | id | na | mandatory | na | product name unique within a Collection, | Data file name | It is important that an Item identifier is unique within a Collection, and that the Collection identifier in turn is unique globally. Then the two can be combined to give a globally unique identifier. Items are strongly recommended to have Collections, and not having one makes it more difficult to be used in the wider STAC ecosystem. If an Item does not have a Collection, then the Item identifier should be unique within its root Catalog or root Collection. | Unique name of the product. | c_gls_NDVI300_202506210000_GLOBE_OLCI_V2.0.1_nc | c_gls_NDVI300_202506210000_GLOBE_OLCI_V2.0.1_nc | |
| nominalDate | DateTimeOffsetAttribute | yes | STAC core attribute | datetime | na | mandatory | na | CLMS specific | This is likely the acquisition (in the case of single camera type captures) or the 'nominal' or representative time in the case of assets that are combined together. Though time can be a complex thing to capture, for this purpose keep in mind the STAC spec is primarily searching for data, so use whatever single date and time is most useful for a user to search for. STAC content extensions may further specify the meaning of the main datetime field, and many will also add more datetime fields. All times in STAC metadata should be in Coordinated Universal Time (UTC). If there's clearly no meaningful single 'nominal' time, it is allowed to use null instead. In this case it is required to specify a temporal interval with the fields start_datetime and end_datetime from common metadata. | The nominal date is the reference date for the data acquisition period covered by the product. This date will be used to extract YYYY/MM/DD in the folderstructure. | 2025-06-21T00:00:00.000000Z | 2025-06-21T00:00:00.000000Z | ||

Time is in UTC | Creation date and time of the corresponding STAC entity or Asset (see below), in UTC. | Date of first creation of the product file. For CLMS data this is the mtime attribute from the rclone copyto info. | 2025-07-02T09:30:01.282075Z | 2025-07-02T09:30:01.282075Z | |
| platformAcronym | StringAttribute | yes | STAC core attribute | constellation | mandatory | mandatory | na | CLMS specific | The name of a logical collection of one or more platforms that have similar payloads and have their orbits arranged in a way to increase the temporal resolution of acquisitions of data with similar geometric and radiometric characteristics. This field allows users to search for related data sets without the need to specify which specific platform the data came from, for example, from either of the Sentinel-2 satellites. Examples include landsat-8 (Landsat-8, a constellation consisting of a single platform), sentinel-2 (Sentinel-2), rapideye (operated by Planet Labs), and modis (NASA EOS satellites Aqua and Terra). In the case of modis, this is technically referring to a pair of sensors on two different satellites, whose data is combined into a series of related products. | List of the platformAcronyms providing the acquisitions used for producing the product. If multiple values, use comma seperator without whitespace. | Sentinel-2 or multimission | Sentinel-2 | ||
| platformShortName | StringAttribute | yes | STAC core attribute | platform | mandatory | mandatory | na | name of the Platform | The unique name of the specific platform the instrument is attached to. For satellites this would be the name of the satellite, whereas for drones this would be a unique name for the drone. Examples include landsat-8 (Landsat-8), sentinel-2a and sentinel-2b (Sentinel-2), terra and aqua (part of NASA EOS, carrying the MODIS instruments), mycorp-uav-034 (hypothetical drone name), and worldview02 (Maxar/DigitalGlobe WorldView-2). | List of the platformShortNames providing the acquisitions used for producing the product.
