Answer and Calculate some questions in Assignment4. You don’t need to answer (v) in Part2.
Provide three powerpoint in class. Maybe can be used to answer and calculate.?
Please do it ASAP. And create a new doc to answer. Thanks
GIS 205 Assignment 4: Aerial Photography and Remote Sensing
Deliverable: A typewritten report, uploaded to Blackboard as a PDF or DOCX document.
Grading: 5 points total, points for each part indicated below.
Part 1: Principles of Aerial Photography. (3 points)
(i) Measure your height in feet and inches. With the help of a friend, go outside at noon
and stand with your back to the sun and measure the length of your shadow in feet and
inches. Use these measurements and the equation given in class to estimate the
latitude of Tempe. (2 points)
(You?ll need to note the date on which you take your measurement).
(ii) What would the length of your shadow be if you repeated this experiment on June 21?
Part 2: Remote Sensing (2 points)
(iii) Describe why there are two identical MODIS sensors flying, one on the Terra and one on
the Aqua satellite? . (Hint- Topic 8 lecture covers this) (0.5 pts)
(iv) NASA has recently launched a new satellite called SMAP (Soil Moisture Active Passive).
Research this new satellite (on the web) and answer the following questions. (0.125 pts
? When was the satellite launched (Month/Day/Year)?
? What is the satellite?s orbit?
? What is the satellite?s height above the earth (km)?
? What is the spatial resolution of the ground measurements from the onboard
Use the NASA Image Composite Explorer tool to look at remote sensing imagery about
rainforests in Panama. Read the information about the ?Rainforests at the Crossroads? project:
Go to exercise 1 and read the information about spectroradiometers:
(v) Create a Color Infrared image for March 2000 with Landsat imagery. (Hint- Use band 4
for Near Infrared. Topic 8 lecture covers what bands should be Red, Green, Blue).
Answer the following questions about the CIR image (1 pt):
? Using the Select Region tool, draw a box approximately 2,000 km2 in an area
comprised mostly of vegetation and create a histogram of the values contained
within your selected area. What is the range of values for the Near Infrared
band? (Hint ? you will need to identify which color is the Near Infrared band).
If you need help, please read the User Guide for the NASA Image Composite Explorer (ICE) tool.
