PE&RS June 2007

The images were obtained using ArcGIS Image Server), a new software product from ESRI that allows you to serve multiple representations of imagery products with dynamic on-the-fly processing, making them accessible and usable as soon as possible, enterprise-wide. The Landsat images show examples of processing operations including applying an algorithm to produce a Normalized Difference Vegetation Index (NDVI), or stacking and enhancing the bands to highlight and help identify various ground features. All of these examples are derived from the same Landsat scenes, which are stored only once in their native format.

Clockwise from top right:

• Bands 4, 3, 2 (RGB) closely resemble traditional color infrared aerial imagery, which is most useful in studying vegetation.
• An NDVI image is used to show relative biomass.
• Bands 7, 4, 2 give a natural appearance to the im age— vegetation is displayed in green shades— while providing alternative shades, such as pink, to distinguish soil characteristics.
• Bands 3, 2, 1 create a true color image representing features with the same color as the human eye.
