Harmonized Landsat Sentinel Service
The Harmonized Landsat-Sentinel Service API produces high-resolution imagery and NDVI data for a desired area-of-interest. From NASA, the Harmonized Landsat-Sentinel-2 project is an initiative to produce a consistent, harmonized surface reflectance product from Landsat and Sentinel-2 data.
b) HLS Service
The Ag-Analytics® Harmonized Landsat-Sentinel Service (HLS) API provides the service in which a user can provide an area-of-interest (AOI) with additional customized options to retrieve the dynamics of their land at various times from the Landsat-8 and Sentinel-2 satellites. This service provides information on cloud cover, statistics, and Normalized Difference Vegetation Index in addition to MSI bands information.
The Harmonized Landsat-Sentinel (HLS) Project is a NASA initiative to produce a Virtual Constellation (VC) of surface reflectance (SR) data from the Operational Land Imager (OLI) and MultiSpectral Instrument (MSI) onboard the Landsat-8 and Sentinel-2 remote sensing satellites, respectively. The data from these satellites creates unprecedented opportunities for timely and accurate observation of Earth status and dynamics at moderate (<30 m) spatial resolution every 2-3 days.
