Description:

Multispectral imagery of the state of Alabama is available from the Geological Survey of Alabama for the time period of 1972-1984. Imagery from the Landsat multispectral scanner (MSS) is available as prints or transparencies for all bands (with selected color composites avaliable) at an approximate scale of 1:1,000,000. MSS data is collected in four spectral bands ranging from 0.5 to 1.1 micrometer with a ground resolution of about 80m. Images available from Skylab 3 and 4 include 9 x 9 prints and transparencies at 1:750,000 (skylab 3) and 1:500,000 (skylab 4). These images were taken in 1973 and are along three tracks; northeast from New Orleans, LA to South Carolina, northeast from Pensacola, FL to Columbus, GA, and from Pearl River, Jackson MI to Pensacola, FL. The multispectral photographic facility onboard Skylab provided imagery in several wavelength bands ranging from 0.5 to 0.9 Micrometers. This camera system provided ground resolution of approximately 40 m in visible wavelengths to 75 m in the infrared. A variety of high and low altitude aircraft imagery of Alabama is also available from the Geological Survey of Alabama. Microfiche images of MSS/TM imagery of North America since 1986 (landsat browse imagery) are also available. Similar imagery for other locations and time periods is available from the Eros Data Center.

Description:

The Global Forest Observations Initiative (GFOI) is an initiative of the inter-governmental Group on Earth Observations (GEO) that aims to:foster the sustained availability of observations for national forest monitoring systems; support governments that are establishing national systems by providing a platform for coordinating observations, providing assistance and guidance on utilising observations, developing accepted methods and protocols, and promoting ongoing research and development; and work with national governments that report into international forest assessments (such as the global Forest Resources Assessment (FRA) of the Food and Agriculture Organization, FAO) and the national greenhouse gas inventories reported to the UN Framework Convention on Climate Change (UNFCCC) using methods of the Intergovernmental Panel on Climate Change (IPCC).

Description:

This data set contains raw unregistered Landsat digital data covering most of Alaska. Data obtained from EROS Data Center in Sioux Falls, South Dakota. Data acquired from 1980 and is ongoing. Some Landsat scenes date back to 1972. The data set currently has 585 records with a growth chart at 5-10 records per year. The amount of storage required varies by medium used or full scene or subscene selection; the file structure is sequential. Spatial referencing of data is by 57 x 59 meter grid cell size-MSS data. Data are available on 9-track, 800 bpi, 1600 bpi, 6250 bpi, unlabeled, unblocked, BCD, fixed record length tape. Subsets and custom formats are available. Limited documentation is available. The data is organized in 7 1/2 ' or 15 ' quads. Data is used for false color composites, land cover analysis, geologic analysis, hydrogeologic analysis, land use planning, basis for update of topographic maps, production of image maps.

Description:

The Landsat Level-1 Collection 2 products, produced by the U.S. Geological Survey (USGS), provide high-quality, calibrated, and georeferenced satellite data that support a wide range of remote sensing applications. This dataset encompasses multispectral data captured by the Landsat 1-9 missions, spanning the period from 1972 to present and offers consistent and accurate measurements of Earth's land surface characteristics. These data are processed to established precise standards, meaning they are radiometrically and geometrically calibrated to ensure high accuracy for scientific analyses. The Level-1 products include per-pixel quality assessment information that provides essential metadata to help users select the most suitable data for their needs.

Description:

INPE's only receiving station for Landsat MSS was located in Cuiaba, MT (geographic coordinates approx. 15.5S/56.0W). Data were acquired routinely over the entire range from 1973 until 1986, some time after TM data began being received. MSS data recordings were then reduced to Brazilian territory only. Also, many gaps exist, some of them several months long, related mostly to station downtimes caused by lightning. The MSS tapes recorded at Cuiaba were air shipped to the processing and distribution center in Cachoeira Paulista, SP, where they are kept. The holdings are estimated to be around 75,000 scenes (or 300,000 images, counting individually each of the four spectral bands), not all of them processed. The fifth band (thermal infrared) available on Landsat 3 is not counted for practical purposes. Very few were processed at INPE with disappointing results and it was soon dropped as a product. Demand for MSS products decreased sharply after TM products started being distributed. This determined the reduction and eventually the discontinuing of MSS recordings in 1987. The original processing system, based on 16-bit minicomputers, was dismantled in early 1991. An alternative ingestion system is being developed to allow limited processing of MSS data by the TM system, with a forecast to be ready in late 1998. Meanwhile, available products are limited to reproduction of existing photographic originals (about 150,000 black-and-white and color images). No digital products can be delivered, since no copies were kept from produced CCTs. Requests for products and for image search listings are handled directly by the processing center (listed at the Data Center entry), through contacts by mail, phone or fax. No online remote access is available to the moment, although plans exist to implement it, including the International Directory protocols. No firm date is speculated for that, but hopes are that it can be made before 1998. Information about costs, delivery time and available formats can be requested at the same address.
