Landsat 8 Cloud Cover Assessment Validation Data

This collection contains 96 Landsat 8 Operational Land Imager (OLI) Thermal Infrared Sensor (TIRS) terrain-corrected (Level-1T) scenes, displayed in the biomes listed below. Manually generated cloud masks are used to validate cloud cover assessment algorithms, which in turn are intended to compute the percentage of cloud cover in each scene.

Each file contains the Landsat 8 Level-1 data band files in .TIF format, the Quality band .TIF file, the metadata file (MTL.txt), and the manual masks in .img (ENVI) format.

The Approximate Cloud Status column represents the estimated percentage of clouds per scene, using the following guide:

 Clear:    less than 35 percent
 MidClouds:    between 35 and 65 percent
 Cloudy:    over 65 percent

 

The interpretation for the bits in each manual mask is as follows:

Value Interpretation
0    Fill
64    Cloud Shadow
128    Clear
192    Thin Cloud
255    Cloud

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
