Remote Sensing

In the final lab of the semester we were required to use a software called MultiSpec. MultiSpec is a processing system for interactively analyzing Earth observational multispectral image data such as that produced by the Landsat series of Earth satellites and hyperspectral image data from current and future airborne and spaceborne systems such as AVIRIS. The objective of MultiSpec is as an aid to export the results of research into devising good methods for analyzing such hyperspectral image data. 

Question 10.8 Why are the areas between the runways red?

  • In this lab, we needed to use a 4-3-2 combination. This is the reason why band 4 was red. 
Question 10.9 Why do the areas in between the runways now appear bright green?
  • Just like the question before, we needed to use a combination of 3-4-2. We had to manually set band 4 to bright green, this is the reason band 4 appears this bright green.
Question 10.10 Why do the areas in between the runway now appear blue?
  • Lastly, we needed to change the color configuration to a 3-2-4. Band 4 is now represented by the color blue.
