Sentinel-2 on AWS Reader Parameters

General

ClosedFeature Type Name(s)

This parameter allows you to choose different naming schemes for a feature type, and the number of feature types generated for the reader.

The Feature Type Name changes, depending on the selection.

SENTINEL2_L1C_TILE_10m

Each Sentinel-2 product contains 15 band options, most of which are true spectrum bands, with Preview and True Colour bands being composite.

The full list of band options is: B0, B1, B2, B3, B4, B5, B6, B7, B8, B8A, B9, B10, B11, B12, PREVIEW and TRUECOLOUR.

ClosedResolutions

The bands can be broken down into four resolution groupings:

  • 10 meter
  • 20 meter
  • 60 meter
  • RGB preview

The resolution-specific datasets consist of the following bands from the original Sentinel-2 data:

  • 10 meter: B2 (490 nm), B3 (560 nm), B4 (665 nm) and B8 (842 nm)
  • 20 meter: B5 (705 nm), B6 (740 nm), B7 (783 nm), B8a (865 nm), B11 (1610 nm) and B12 (2190 nm)
  • 60 meter: B1 (443 nm), B9 (940 nm) and B10 (1375 nm)

Spatial Filter

ClosedMilitary Grid Reference System

The Military Grid Reference System (MGRS) is a standard designed for use with the Universal Transverse Mercator (UTM) and Universal Polar Stereographic (UPS) grids. MGRS position coordinates are identified by letters and numbers that include grid zone, 100,000-meter square letter identification, and grid coordinates.

  • Select a UTM Zone between 1 and 60.
  • Select a UTM Latitude Band between C and X, excluding I and O.
  • Select an MGRS Square valid for the selected zone and band. The ID is a two-letter identifier. First letter: A-Z, excluding I and O. Second letter: A-V, excluding I and O. A particular grid zone will not have all possible MGRS square IDs.

For technical information about MGRS, see the DMA Technical Manual.

ClosedEnvelope

Using the minimum and maximum latitude and longitude parameters, define a bounding box that will be used to filter the input features. Only features that intersect with the bounding box are returned.

If all four coordinates of the search envelope are specified as 0, the search envelope will be disabled.

Coordinates must be in LL84.

Date Filter

ClosedDate Filter
  • Latest: Get the latest imagery only for the selected grid squares. This may produce more than one feature if there is more than one sequence available for a particular grid square on any of the specified dates.
  • All: Get all available imagery for the selected grid squares.
  • Date Range: Type the start and end dates, or select them from the displayed calendars.
  • Selected Dates: A date is displayed if one or more of the selected grid squares are available on that date. Selecting a date will download all grid squares inside the selection which are available on the selected date.
ClosedQuality Filter
  • Maximum Percentage Cloud Cover: The maximum percentage of the image that may contain cloud cover. Images with more cloud cover than this threshold are skipped.
  • Minimum Data Quality Assessment: The minimum percentage of the image that contains usable data. Images with less usable data than this threshold are skipped.

Schema Attributes

ClosedAdditional Attributes to Expose

Use this parameter to expose Format Attributes in Workbench when you create a workspace:

  • In a dynamic scenario, it means these attributes can be passed to the output dataset at runtime.
  • In a non-dynamic scenario, you can use this parameter to expose additional attributes on multiple feature types.
