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.

Spatial Analysis

Cities With Population Of 25,000 Or More
(Light Blue Dots)
It took a while to finally get ArcGIS to install on a Mac. But once I figured out how, and began this lab I actually had a fun time with it. In the beginning of the lab I was a little confused with the program due to it having so many capabilities. After messing around with the program for a little while I finally got it figured out. For this lab I chose Maine as my state to work with. For the state of Maine I looked at 3 things.            First, I looked at cities with a population of 25,000 or more.  These cities appear on the make as the light blue dots. Next, I looked at what States touch Maine. As you can see in the Map below only New Hampshire touches Maine. Lastly, I Found all the main roads that intersect Maine. After doing this lab I feel much more comfortable with the program.

GPS Introduction

During this lab I used My Tracks, the android application recommended for this assignment. After I downloaded, and familiarized myself with the app I began to drive around my neighborhood and track the locations of fire hydrants.

At each fire hydrant location, I used a waypoint marker to pinpoint each location and recorded its condition. My Tracks made this lab extremely easy, because it does all the work for you and is very user friendly. I would definitely recommend this application to anyone who would be doing similar assignments or activities. I actually plan on using it to pinpoint great fishing and hunting spots that I come across. For example, I want to be able to pinpoint how many fish I catch, as well as the species of fish that was caught; the amount of ducks I shot, the location, and during what season. I look forward to using this app again!

Lastly,  I wanted to quickly comment on the easiness of uploading the KML files to GE. You can actually download the GPX file directly from My Tracks, and then upload that file as a KML file into GE. It was so easy!

Cylindrical Projections

I wanted to do more research on Cylindrical Projections because they seem to be the most simple. A cylindrical projection can be imagined in its simplest form as a cylinder that has been wrapped around a globe at the equator.

I thought that the simplicity of this type of projection is what made it so interesting. As you can see in the image above, wrapping the Earth in a cylinder places horizontal and vertical lines that correspond with latitude and longitude.
