Description
A global reference grid for Landsat 4, 5, 7, 8, and 9 satellite imagery, using the Worldwide Reference System-2 (WRS-2). The dataset, sourced from the USGS and hosted by the Australian Ocean Data Network, provides path and row identifiers for locating daytime scenes. It is intended as a reference layer for determining the approximate extent of imagery, though the polygon boundaries are noted to be indicative and not perfectly match the actual image footprints.
Use Cases
Identifying the correct Landsat scene for a study area based on WRS-2 path and row identifiers.
Approximating the geographic extent of Landsat 4-9 imagery for project planning.
Creating a reference map layer to visualize the global Landsat tiling system.
Strengths
Covers the global tiling system for a major Earth observation program (Landsat 4-9).
Specifically describes the WRS-2 system used for daytime descending scenes.
Sourced from the authoritative USGS and cached for availability.
Limitations
The scene polygon boundaries are only indicative; they do not precisely match the shape or location of actual Landsat 5, 8, and 9 imagery.
Description metadata is limited; actual data quality and structure require manual inspection after download.
Column-level documentation is absent; field semantics must be inferred after download.
Provenance

The dataset is explicitly noted as not suitable for use as a clipping mask for Landsat imagery due to geometric discrepancies between the grid polygons and the actual images.
