The Operational Land Imager (OLI) and the Thermal Infrared Scanner (TIRS) are the two instruments carried on board Landsat 8 (also known as LDCM - Landsat Data Continuity Mission) satellite.
These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 metres (visible, NIR, SWIR), 100 metres (thermal) and 15 metres (panchromatic). The spectral coverage and radiometric performance (accuracy, dynamic range, and precision) are designed to detect and characterise multi-decadal land cover change in concert with historic Landsat data.
The OLI provides two new spectral bands in respect to the Landsat 7 ETM+ instrument, one tailored especially for detecting cirrus clouds and the other for coastal zone observations, and the TIRS collects data for two more narrow spectral bands in the thermal. The nominal schedules expect the collection of at least 400 OLI and TIRS scenes per day where each scene is a digital image covering a 185-by-180 km surface area.
The objective of scheduling and data collection is to provide cloud-free coverage of the global landmass on a seasonal basis. The main objective of ESA's implementation of the Landsat 8 PDGS is the provision of the LDCM data to the European user community within 3 hours after the sensing time.

Due to scheduled maintenance activities, searching for some Third Party Missions collections in the EOLI-SA Catalogue may temporarily be unavailable on Wednesday 19 April 2017, from 09:00 to 17:00 CEST.

A new processing tool has been developed to bundle information contained in large amounts of satellite data, paving the way for the wealth of Copernicus Sentinel satellite data to be more easily incorporated into online environment-monitoring services.
