These maps provide the user community with land cover type, land cover change, metrics characterizing the magnitude and seasonality of greenness of each pixel, and the magnitude of change.

The HLSL30 product provides 30-m Nadir Bidirectional Reflectance Distribution Function (BRDF)-Adjusted Reflectance (NBAR) and is derived from Landsat 8/9 OLI data products.

A low-resolution red, green, blue (RGB) browse image of bands 5, 4, 3 is also available for each granule.Known Issues GWELDMO known issues can be found in Section 4 of the Algorithm Theoretical Basis Document (ATBD).Improvements/Changes from Previous Versions Version 3.1 products use Landsat Collection 1 products as input and have improved per ...

Jan 25, 2021 · With the long awaited release of the provisional Harmonized Landsat and Sentinel-2 (HLS) version 1.5 data, GIBS and Worldview have worked hard to get this 30 meter imagery into Worldview.

To avoid errors when using the CFMask_State layer, bit 0 should be ignored as an indicator of fill value.Improvements/Changes from Previous Versions GWELD Version 3.2 products now use Landsat Collection 2 products as input while previous GWELD versions use Landsat Collection 1.

Apr 11, 2013 · The Harmonized Landsat Sentinel-2 (HLS) project provides consistent surface reflectance (SR) and top of atmosphere (TOA) brightness data from a virtual constellation of satellite sensors.

Feb 25, 2025 · NASA Worldview has added an “Available Imagery Dates” selector to help users find Harmonized Landsat and Sentinel-2 (HLS) imagery for their area of interest.

The HLSL30 Vegetation Indices (HLSL30_VI) product is derived from Landsat 8 and Landsat 9 OLI data products. Vegetation indices combine specific bands of satellite data to quantify various aspects of vegetation.

Landsat 8 image data files consist of 11 spectral bands with a spatial resolution of 30 meters for bands 1-7 and bands 9-11; 15-meters for the panchromatic band 8. Delivered Landsat 8 Level-1 data typically include both OLI and TIRS data files; however, there may be OLI-only and/or TIRS-only scenes in the USGS archive.

The Operational Land Imager (OLI) is housed aboard the joint NASA/USGS Landsat 8 and Landsat 9 satellites, while the Multi-Spectral Instrument (MSI) is mounted aboard Europe’s Copernicus Sentinel-2A, Sentinel-2B, and Sentinel-2C satellites.
