The Landsat satellite record stretches from 1972 to the present. This gallery includes all Landsat images published on the Earth Observatory, Visible Earth, and Landsat Science web sites from all seven Landsat satellites (Landsats 1-8, Landsat 6 failed to achieve orbit). All of the images are in the public domain and may be used with attribution. The correct attribution for imagery obtained. Since 1972, the joint NASA/ U.S. Geological Survey Landsat series of Earth Observation satellites have continuously acquired images of the Earth's land surface, providing uninterrupted data to help land managers and policymakers make informed decisions about natural resources and the environment. Landsat is a part of the USGS National Land Imaging (NLI) Program. Latest Landsat Headlines. The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth.It is a joint NASA/USGS program. On July 23, 1972 the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat. The most recent, Landsat 8, was launched on February 11, 2013.The instruments on the Landsat satellites have acquired millions of images Newly acquired Landsat 7 and Landsat 8 scenes become available for download typically less than 12 hours after data acquisition. On the EarthExplorer Data Sets tab, Level-1 scenes can be found under the Landsat category, Landsat Collection 1 Level-1 subcategory, as shown in the image below
Welcome to the LandsatLook Viewer! The LandsatLook Viewer is a prototype tool that was developed to allow rapid online viewing and access to the USGS Landsat image archives. This viewer allows you to: Interactively explore the Landsat archive at up to full resolution directly from a common Web browser; Search for specific Landsat images based on area of interest, acquisition date, or cloud. When the archive was opened, there were more Landsat images outside it than in it. Many images were retained by the global network of receiving stations. An effort to consolidate these has added more than 3 million images to the repository since 2010; agreements are in place for a further 2 million to be ingested. — Wulder & Coops , Sep 4, 2014 + more quotes With a launch in 2023. Landsat 8 Launched on February 11, 2013, Landsat 8 (formerly the Landsat Data Continuity Mission, LDCM) is the most recently launched Landsat satellite. It is collecting valuable data and imagery used in agriculture, education, business, science, and government

11. Creating a Composite Image from Landsat Imagery. And, listed as the top file in the list of files in the Image Analysis window: Next, let's discuss what we see in the Table of Contents. It shows Band 1 as Red, Band 2 as Green, and Band 3 as Blue. But remember from th The Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) sensors capture reflected solar energy, convert these data to radiance, then rescale this data into an 8-bit digital number (DN) with a range between 0 and 255. It is possible to manually convert these DNs to ToA Reflectance using a two-step process. The first step is to convert the DNs to radiance values using the bias.

Landsat collects images in long narrow strips called swaths. Each swath is 185 kilometers (115 miles) wide and is 2,752 kilometers (1,710 miles) from the next adjacent swath taken that day. It takes 16 days for the swaths to overlap enough to image the whole Earth. Previous Landsat sensors swept back and forth across the swath like a whisk broom to collect data

The instruments on the Landsat satellites have acquired millions of images. The first three satellites caried the Multispectral Scanner (MSS) as the main imaging instrument with a Return Beam Vidicom (RBV) as a subsidiary The images from the Landsat 8 could also be used to monitor agricultural practices, road and city construction, deforestation, and changes in sea ice among others. In order to carry out its mission, the next step for the Landsat 8 is the calibration of its instruments. Settings on the spacecraft have to be adjusted so that it can accurately measure the light that its sensors pick up. One of.
