These data products are being distributed free of charge. Recipients have a responsibility to:

Acknowledge the University of New Hampshire, EOS-WEBSTER Earth Science Information Partner (ESIP) as the data distributor of this dataset.

Additionally, if you create derivative products from these data, or if you have additional Landsat 7 data, or Landsat 5 data that are 10 or more years old, and you would like to provide them to EOS-WEBSTER to distribute freely to other scientists and the general public, please contact our User Support personnel.

Summary:

With the launch of Landsat 7, data are no longer copyright protected and these data may be freely distributed. EOS-WEBSTER, in an effort to provide access to earth science data, has designed an interim system to make Landsat data that we have in our database available to other users. In many cases, in-house researchers have acquired these data directly from the USGS EROS Data Center (EDC) for their research projects. They have provided copies of their data to EOS-WEBSTER for distribution to a wide audience. Therefore, our data holdings come from several different sources and can have a variety of different processing levels associated with them. We have attempted to document, to the best of our ability, the processing steps each Landsat scene has been through. Our data are currently served in two output formats: BSQ and ERDAS Imagine, and three different spectral types (when available): multispectral, panchromatic, and thermal. A header file is provided with each ordered image giving the specifics of the image.

Please refer to the references to learn more about Landsat and the data this satellite acquires. We hope to add more data as it becomes available to EOS-WEBSTER. If you have any Landsat data that you are willing to share, EOS-WEBSTER can provide access to it to a broad audience by adding it to our database. Landsat 7 data and Landsat 5 data older than 10 years can be distributed without copyright restrictions. Please contact our User Support personnel if you would like to distribute your Landsat data, or other earth science products, via EOS-WEBSTER's FREE data distribution mechanism.

In the near future we hope to release a new Satellite Interface, which would allow a user to search for satellite data from a number of platforms based on user-selected search parameters and then sub-set the data and choose an appropriate output format.

If you have any other questions regarding our Landsat data holdings, please contact our User Support personnel.

Available Data Sets:

Five catelogues are available: United States, Russian, South America, Southeast Asia, and Other Landsat scenes. These catalogues may be searched separately by clicking on the Landsat Data icon on the data page. Tables 1-3 provide the current scenes available in these catalogues.

Spatial & Temporal Scales

Our database has three separate catalogues that can be searched independently: 1) Landsat data for the domain of the United States, 2) Landsat data for the domain of Russia/East Asia, and 3) Other Landsat scenes for other regions of the world.

The spatial scale of these data are defined by the WRS Path & Row designations. Please see the footprint map for each catalogue to see the approximate spatial coverage of our Landsat scenes, or the search system for exact locations of the Landsat Path & Row scenes held by the EOS-WEBSTER database.

Note on Landsat WRS1 vs. WRS2 Referencing Systems: Please note that in 1983 the path/row referencing system used to index landsat data changed from the World Referencing System 1 (WRS1) to the World Referencing System 2 (WRS2) to correspond with the differences in orbits of landsat 1,2, and 3 vs. 4,5, and 7 respectively. Though the two referencing systems correspond in their indexing of rows, all paths are slightly shifted between the two systems resulting in different paths for the same location on the ground. Please be aware of this shift when attempting to order corresponding scenes referenced in the two different systems.

Footprint Maps:

The temporal range of Landsat data which are in the EOS-WEBSTER holdings are defined in the above tables.

Data Format:

The data are currently held in EOS-WEBSTER in two different formats:

Generic Binary/Band Sequential (BSQ) with separate header file
ERDAS Imagine (.img)
Browse Image (.jpg)

Data can be ordered by spectral type. For Landsat 7, three spectral types are available: 1) Multispectral (bands 1-5 & 7), 2) Panchromatic (pan), and 3) Thermal (bands 6 a&b) (see Table 2). The multispectral (ms) files contain six bands of data, the panchromatic (pan) files contains one band of data, and the thermal (therm) files contain two bands of data representing a high and low sensor gain.

A header file is provided for both data formats, though a header file is not needed to open the .img file using software programs which have the capability of reading .img files.
