- The combination of Bands 7,4 and 2 used to prepare this mosaic provides a "natural-like" rendition, while also penetrating atmospheric particles and smoke. Healthy vegetation will be a bright green and can saturate in seasons of heavy growth, grasslands will appear green, pink areas represent barren soil, oranges and browns represent sparsely vegetated areas. Dry vegetation will be orange and water will be blue. Sands, soils and minerals are highlighted in a multitude of colors. This band combination provides striking imagery for desert regions, and is useful for geological, agricultural and wetland studies. If there were any fires in this image they would appear red. This combination is used in the fire management applications for post-fire analysis of burned and non burned forested areas. Urban areas appear in varying shades of magenta. Grasslands appear as light green. The light-green spots inside the city indicate grassy land cover - parks, cemeteries, golf courses. Olive-green to bright-green hues normally indicate forested areas with coniferous forest being darker green than deciduous. This description is from Portland State University Image Processing class notes, available here: http://web.pdx.edu/~emch/ip1/bandcombinations.html . Band 7 (2.08 -2.35u m): has separated land and water sharply. Band 7 has a strong water absorption region, and a strong reflectance region for soil and rock. Urban areas, croplands, highways, bare croplands have appeared as bright tone, and water body, forest have appeared as dark tone. Band 4 (0.76 - 0.90u m): operates in the best spectral region to distinguish vegetation varieties and conditions. Because water is a strong absorber of near IR, this band has delineated water bodies (lakes and sinkholes), distinguished between dry and moist soils (barren land and croplands). In this band croplands and grasslands have showed higher reflectance (brighter tone) than the forest. This band has also separated croplands from bare croplands. Since standing crops (vegetation) has higher reflectance in the near IR region, they have appeared as brighter tone, and due to presence of moisture content in the bare croplands, they have appeared as darker tone. In the band 4 barren lands, urban areas and highways have not been highlighted and they appeared as dark tone. Band 4 is useful for crop identification and emphasizes soil-crop and land-water contrast. Band 2 (0.52 - 0.60u m): it is sensitive to water turbidity differences. Because it covers the green reflectance peak from leaf surfaces, it has separated vegetation (forest, croplands with standing crops) from soil. In this band barren lands urban areas and roads and highways have appeared as brighter (lighter) tone, but forest, vegetation, bare croplands, croplands with standing crops have appeared as dark (black) tone.
- Abstract
- This image is a mosaic of Landsat 7 Enhanced Thematic Mapper Plus (ETM+) pan sharpened imagery, covering Wisconsin and parts of adjoining states. The image resolution is 14.25 meters by 14.25 meters. The image has been projected to Wisconsin Transverse Mercator (see http://dnr.wi.gov/maps/gis/wtm8391.html). The Tri-Decadal Global Landsat Orthorectified ETM+ Pan Mosaic browse images are displayed as a 7,4,2 (RGB) color composite. (Note that when loaded into ArcView, these are labelled Bands 1,2,3.) The mosaic covers a 5 degree (north-south) segment of a standard 6 degree wide (east-west) UTM zone. It is further subdivided into four 2.5 degree by 3 degree quadrants. The original browse images were generated from full-resolution data that is orthorectified and UTM-projected, using the World Geodetic System 1984 datum. Full-resolution data may be downloaded from the USGS Global Visualization Viewer (GloVis) at no charge: http://glovis.usgs.gov/AboutBrowse.shtml .
- Purpose
- Wisconsin DNR staff downloaded the Landsat mosaics in March 2010 from the USGS Global Visualization Viewer (GloVis) for use as a small-scale image backdrop for WDNR image services.
