Service Description:

This image service contains global Landsat TM imagery from the 1990 timeframe. The Landsat TM imagery was dynamically processed using the Tasseled Cap transform which is ideal for monitoring vegetation health and vigor, as well as urban growth. It is based on the tasseled cap transformation concept implemented by Kauth and Thomas (1976) and modified for Landsat TM by Crist and Cicone (1984), for monitoring vegetation development over a growing season and predicting crop maturity and yields.

The tasseled cap transformation is a special case of principle components analysis (PCA) where the original Landsat bands are transformed into three main components; Brightness which contains most of the variability in the image and is similar to panchromatic imagery, Greenness which is ideal for discriminating between plant species and vigor, and Wetness which is related to water and moist features. The remaining bands contain noise such as haze, clouds and atmospheric affects. Brightness, Greenness and Wetness are displayed as red, green and blue respectively, where bright man-made and natural areas are red, vegetation is green and wet or moist features are blue.

Time Enabled: Yes. (Start Time Field: GLS_START_DATE; End Time Field: GLS_END_DATE)

Data Source: This image service was compiled from Global Land Survey (GLS) datasets: 1990. GLS datasets are created by the United States Geological Survey (USGS) and the National Aeronautics and Space Administration (NASA) using Landsat images. These global minimal-cloud cover, orthorectified Landsat data products support global assessments of land-cover, land cover-change, and ecosystem dynamics such as disturbance and vegetation health.
