back to Satellite Product List Product DescriptionNorth American Landscape Characterization (NALC) data consists of Landsat Multi-Spectral Scanner (MSS) time-series triplicates that were acquired in 1973, 1986, and 1991 (+/- one year). The data covers selected locations throughout the conterminous U.S. and Mexico. Each NALC triplicate will consist of at least one MSS scene or scene composite for each of the selected years. The specific temporal windows will vary for geographical regions, based on the seasonal characteristics of the vegetation. Most images are single-scene acquisitions. However some individual scenes may be multi-temporal composites if a high-quality cloud-free single scene was not available. In most cases, the 1980`s image has been precision corrected. The 1970`s and 1990`s scenes have been radiometrically and geometrically corrected, and are coregistered to the 1980`s image. Pixel size for all images is 60 meters. The data has been cast to the Universal Transverse Mercator (UTM) projection and is referenced to the North American Datum of 1927 (NAD27). The files are available in generic binary format and are distributed on CD-ROM, DVD, or are available to download. Additional Information: Back to TopPrices
