HLS-Data-Resources

Welcome! This repository provides guides, short how-tos, and tutorials to help users access and work with Harmonized Landsat Sentinel-2 (HLS) data. In the interest of open science this repository has been made public but is still under active development. All Jupyter notebooks and scripts should be functional, however, changes or additions may be made. Contributions from all parties are welcome.

Resources

Below are data use resources available HLS data.

Name Type/Link Summary Services and Tools

Additionally, the LPDAAC-Data-Resources Repository has general resources associated with datasets hosted by the LP DAAC, as well as links to other repositories for specific datasets such as EMIT, ECOSTRESS, and GEDI.

HLS Background

The Harmonized Landsat Sentinel-2 (HLS) project produces seamless, harmonized surface reflectance data from the Operational Land Imager (OLI) and Multi-Spectral Instrument (MSI) aboard Landsat and Sentinel-2 Earth-observing satellites, respectively. The aim is to produce seamless products with normalized parameters, which include atmospheric correction, cloud and cloud-shadow masking, geographic co-registration and common gridding, normalized bidirectional reflectance distribution function, and spectral band adjustment. This will provide global observation of the Earth’s surface every 2-3 days with 30 meter spatial resolution. One of the major applications that will benefit from HLS is agriculture assessment and monitoring, which is used as the use case for this tutorial.

Prerequisites/Setup Instructions

Instructions for setting up a compatible environment for accessing HLS data are linked to below.
