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.

Interactive Map-Detroit

Making an interactive map was much easier than I thought it would be. ArcGIS gave step by step instruction to follow that were very clear and easy to understand. In my interactive map I chose the city of Detroit's sports teams. I pointed out on the map where each team plays with a marker that is a basketball, soccer ball, and a tennis ball. This way my markers reflect the theme of my map.

Population Density Maps

The first map posted below is a choroplethic map. In this map I show the population density of Michigan by persons per square mile. In my maps legend you can see the color coding for counties. It looks like the majority of Michigan's population is located in the lower peninsula. More specifically in the Southeastern section of the state surrounding Wayne County.
This second map below is a dot density map. This map also show the population of Michigan. As you can see in my map legend one dot is equal to two thousand people. Once again you can see the majority of the population is located in the southeastern section of the state surrounding Wayne County.
