Here's the link to my map, which shows the roads and railways around my hometown of Wyandotte, MI. I'm not sure if this is embedded correctly, or if there's something else I need to do. However, I will fix it as soon as I get feedback.

Thanks!

How Satellite Remote Sensing Works / Assignment

Remote sensing by definition is, "the technique of obtaining information about objects through the analysis of data collected by special instruments that are not in physical contact with the objects of investigation." In up to date utilization, the term usually implies the utilization of aeronautical sensor innovations to locate and classify things on Earth (both on the ground, in ocean, and skies) by method of propogated signals such as electromagnetic radiation emitted from aircraft or satellites.

Active remote sensing and Passive remote sensing are the two most common types of remote sensing. Active remote sensing emits energy itself onto objects and areas  and a sensor picks up and measures the reflected radiation. . Radar is an example of active remote sensing where the time between discharge and return is measured, securing the location, direction, and speed of the object. Passive sensors distinguish natural radiation that's reflected by the item or its surroundings. Reflection from the sun is the most common form of passive remote sensing. One example of this type of passive sensing is photography.

"Digital aerial photography showing devastation in Ocean Springs, Mississippi. This imagery was acquired by NOAA on August 30, 2005, one day after Hurricane Katrina slammed the region."

Radar shown here provides the monitoring of ice sheets which can be used to assess the threat of rising sea levels.

This shows the interaction between satellite and radiation in order to form images.

Activity 1

This is the 1-channel Thematic display type map showing MODIS NDVI that I made after learning the basic applications of multispec.



                                                                          Activity 2

Shown below are 3 finalized map images showing Linear, Equal area, and Gaussian stretches, in ordewr from left to right. We also learned how to use min/max and that is represented by showing enire range, 2% clipped, and 4% clipped, alos from left to right.

                                                                          Activity 3

              This map portrays unsupervised classification with each cluster showing a different area of soil/vegetation

                                                                           Activity 4

This map shows supervised classification of an image file by selecting training areas for selected classes from known areas.

 

Thematic Mapping and Cartography Assignment




 Population distribution in Michigan is most dense in Southeastern Michigan, in and around metro Detroit. From Wayne county, the population sprawls outward in all directions until the south central region of the state, where the population becomes sparse. This low density is also the trend of the northen counties and counties of the upper peninsula. Once you reach the western part of the state, and specifically the southwestern portion, the population increases again. The hispanic population follows the same trend pattern as general population density.

Fire Hydros GPS

I used my smartphone with the Commander Compass application in order to GPS coordinates of local fire hydrants. The process was fairly simple, my grandmother and I walked around and at each hydrant I took a screenshot of what the Compass GPS was showing. A few people thought I was taking pictures of their fire hydrants, which led to some interesting conversations. Originally, I loaded the coordinates wrong when making my .csv file, which led to my coordinates showing Grosse Ile, MI instead in Dearborn when I uploaded the KML file to google earth. Fortunately, it didn't take too long to correct the problem.
