Every Pixel - Processing Data

Once the ground stations receive data from Landsat, there's still a lot of processing to make every pixel usable. Here's an overview of some of that work.

GOES-16 and Landsat 8

These infrared satellite images were collected on May 24, 2019 over the Washington, D.C. area.

The larger image comes from the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellite (GOES) 16, a geostationary spacecraft at 22,500 miles. The near infrared image has a resolution of 1 kilometer per pixel. The smaller
