PI&RS Module 4: Spatial & Spectral Enhancements and Band Indices
Hello friends, In module 4, I learned how to apply spatial enhancements, which is a preprocessing step that gets the imagery ready for use and how to generate band indices and view the characteristics of multispectral imagery. I used ERDAS Image to examine the images and transfered the map to ArcGIS for the layouts. The map shows false image color imagery. Vegetation appears in shades of red, and densly populated urban areas are shown in cyan blue. This band combination gives results similar to traditional color infrared aerial photography. This map shows TM false natural color. This band combination provides the user with a great amount of information and color contrast. Healthy vegetation is bright green and soil is mauve. This combination is useful for vegetation studies. This map shows true color imagery covering snow feature. The dark olive green shows vegetation while the white shows the snow on top of the mountains. This band is similar to wha...
