Remote Sensing Scientific Visualizations
The following remote sensing visualizations allow you to display a subset of a multiband remote sensing satellite image (Landsat ETM), plot profiles of pixel values at locations of your choice, and create scatterplots. These webpages allow you to interactively display images when you do not have image processing software installed on your computer. Enjoy!
- select a band combination of your choice to display the image
- to create a false color composite (color-infrared), select band 4 (near infrared) for the Red color gun of your display, band 3 (red) for Green, and band 2 (green) for Blue. In other words, assign Band4-Band3-Band2 in this order to RGB
- what is the band combination you would choose for a normal color composite?
- scatterplots or feature space plots (individual bands of remotely sensed data are often referred to as features in the pattern recognition literature) show the frequency of occurrence of brightness values in two bands
- display one band at a time using a grayscale image display
- click on the image at the location of your choice to display pixel value profiles, along rows and columns, and also a spectral profile
