Note: This site provides HTTP file transfer access to the TexasView public Landsat archives. A more robust, "visual" presentation of these data is available through TexasView GloVis. These data may be freely downloaded and used by anyone. The site is provided as a public service by the Forest Resources Institute (FRI), Stephen F. Austin State University(SFASU), in cooperation with the TexasView Remote Sensing Consortium, The Texas Natural Resources Information System (TNRIS) and the Center for Space Research(CSR) at the University of Texas in Austin.

Landsat data on this site are provided in multiple formats and are organized by Path/Row. Each available scene for a particular path/row is archived in a seperate directory structure. Clicking on a path/row in the map above will take you to an FTP directory containing a subdirectory that scene. The subdirectory names reflect the acquisition data of the scene contained within it, organized by year and day of year. If you prefer a month-day-year notation, please use TexasView Glovis.

At present, four Landsat data sets are available through this interface, Landsat 7 ETM+ data, Landsat 4 and 5 Thematic Mapper(TM) data, the Landsat ETM+ Ortho product, and North American Land Chariterization (NALC). Select the desired dataset using the pull-down menu above the map. Not all data sets include data for all path/rows. You will get a "No Data Available" response if you click on a path/row for which we currently have no data of the selected type. If this happens, please select another data set and try again..

SCENE FOLDER CONTENTS
Folder contents vary with the data sets. Landsat Ortho and NALC data have only one scene (one triplicate scene in the case of NALC) for each path/row. The other data sets may contain many scenes acquired on different dates, organized by year and day-of-year. A simple Moth/Day/Year to Day-of-year converter can be found HERE.

Within the scene folder, various data formats are avaialble. All data is available in NLAPS format. Many scenes are also available in three band geotiff and Jpeg formats. Other format, such as ERDAS .IMG.

FILE NAMING CONVENTION:
The file naming conventions vary by data sets. NLAPS data retains the original NLAPS naming. Derived products, such as the three and conposite geotiff and jpeg files use the following naming convention:

p25r37_1999_11_14_321.tif

p25r37 - Path 25, Row 37
1999_11_14 - the acquisition date
321 - bands 3, 2, 1
.tif - TIFF file format

In some cases the file name may be too long to display completely in your browser. Usually, it is only the extension that is missing. Remembering that the TIFF World file (.tfw) will be listed before the TIFF data file (.tif) will help.

A better discovery tool for some of these data is available through TexasView GloVis, particularly if you are uncertain which scenes you are interested in. Please give it a try. Please note that at present, the TexasView GloVIS instance does not contain the Landsat ETM+ Ortho or NALC data sets.
