Originally, the National Aeronautics and Space Administration (NASA) was responsible for operating the Landsat satellites through the early 1980s. In January 1983 operations of the Landsat system were transferred to the National Oceanic and Atmospheric Administration (NOAA). In October 1985 the Landsat system was commercialized. After that date, all Landsat commercial rights became the property of Space Imaging, with exclusive sales rights to all U.S. thematic mapper (TM) data. Throughout these changes, the USGS retained primary responsibility as the Government's long-term archive of Landsat data. As of July 1, 2001, Space Imaging relinquished their commercial right to Landsat data. The Land Remote Sensing Policy Act of 1992 (Public Law 102-555) officially authorized the government and assigned responsibility to the Department of Interior delegated down to the USGS.

Description:

Abstract:

The idea of a civilian Earth resources satellite was conceived in the Department of Interior in the mid-1960s. The National Aeronautics and Space Administration (NASA) embarked on an initiative to develop and launch the first Earth monitoring satellite to meet the needs of resource managers and Earth scientists. The USGS entered into a partnership with NASA in the early 1970s to assume responsibility for the archive management and distribution of Landsat data products. On July 23, 1972, NASA launched the first in a series of satellites designed to provide repetitive global coverage of the Earth's land masses. Designated initially as the Earth Resources Technology Satellite-A (ERTS-A), it used a Nimbus-type platform that was modified to carry sensor systems and data relay equipment. When operational orbit was achieved, it was designated ERTS-1. The second in this series of Earth resources satellites (designated ERTS-B) was launched January 22, 1975. It was renamed Landsat 2 by NASA, which also renamed ERTS-1 to Landsat 1. Three additional Landsats were launched in 1978, 1982, and 1984 (Landsats 3, 4, and 5 respectively). Each successive satellite had improved sensor and communications capabilities. NASA was responsible for operation of the Landsats until the early 1980s. In January 1983 operations of the Landsat system were transferred to the National Oceanic and Atmospheric Administration. The Landsat system was commercialized in 1985 and became the property of Space Imaging EOSAT (later, Space Imaging) who maintained responsibility until July 1, 200l when control was returned to the Federal Government.

Purpose:

The USGS Center for Earth Resources Observation and Science (EROS) has managed the Landsat data archive since the launch of Landsat 1. This archive provides a rich collection of information about the Earth's land surface. Major characteristics and changes to the surface of the planet can be detected, measured, and analyzed using Landsat data. The effects of desertification, deforestation, pollution, cataclysmic volcanic activity, and other natural and anthropogenic events can be examined using data acquired from the Landsat series of Earth-observing satellites. The information obtainable from the historical and current Landsat data play a key role in studying changes to the Earth's surface. Landsat data have been used by government, commercial, industrial, civilian, and educational communities in the US and worldwide. They are being used to support a wide range of applications in such areas as global change research, agriculture, forestry, geology, resources management, geography, mapping, water quality, and oceanography. The types of changes that can be identified include agricultural development, deforestation, natural disaster, urbanization, and the development and degradation of water resources.

Supplemental_Information:

Landsat data is available from the USGS. In addition to its Landsat data management responsibility, the USGS investigates new methods of characterizing and studying changes on the land surface with Landsat data.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The identification of features is provided by the distinct electromagnetic energy it emits, reflects, or otherwise transmits. This is called the spectral signature. Other signatures such as tone (lightness or darkness), texture (surface roughness or smoothness), pattern, shadow, shape, and size are as important. Thus, through the use of the thematic mapper sensor, such elements as water features, soils, and vegetation can be identified and distinguished from each other.

Logical_Consistency_Report: N/A

Completeness_Report:

The Landsat platforms operate from a sun-synchronous, near-polar orbit imaging the same 185 km (115 miles) ground swath every 16 days. The landsat system provides for global data between 81 degrees north latitude and 81 degrees south latitude.

Process_Step:

Process_Description:

The EROS Landsat processing system is the National Landsat Archive Production System (NLAPS) System. The Modular Multi-Satellite Preprocessor (MMSP) receives the serial TM-A (radiometrically corrected) or TM-R (radiometrically and geometrically corrected) data from the DCRSi cassette drive. Data resampling begins after the completion of satellite orbit model generation/refinement and radiometric calibration. Data resampling consists of three distinct components; coarse resampling table generation, resampling table densification, and two-dimensional convolution resampling. Coarse table generation consists of calculating relationships between product line/pixel values at a set of grid-points and the corresponding line/pixel values in the raw data. Table densification consists of interpolating similar relationships between the remaining product line/pixel values and the corresponding raw data line/pixel values. Table densification also includes performing a number of corrections to the interpolation to account for various inaccuracies in the raw data.
