One of the requirements for this course is to find a remote sensing image on the Web and present it to the class. A "suitable" image is one which:

- you personally find interesting;
- (mostly) fits on one screen without scrolling;
- you are able to provide the following details:

• the location of the area captured in the image
• URL (the link to the image)
• satellite name
• sensor name
• sensor bands or channels used in creating the image (for example, bands 234, or thermal or radar etc.)
• image acquisition date
• spatial resolution of the image

Marks will be assigned as follows:

- 2 marks for having a "suitable" image (this includes providing the requested details (as defined above) about the image)
- 6 marks for a description of the "significance" of the image for physical geography and human geography.
For your "significance" discussion, you could address such topics as: Did you learn anything new? Or, How can these data be used by decision-makers? Include at least 3 points for each of the human and physical geography descriptions.
- 2 marks for your oral presentation: Did you speak loudly, clearly, enthusiastically, and succinctly? Did you try to engage the class in discussion?

Image presentations will take place at the end of the lecture period. Limit your oral presentation to 2-3 minutes in length. Alejandro will introduce you to Powerpoint in the first lab -- I strongly encourage you to use it in your presentation. Doing so will ensure that you can succinctly provide the required information during your presentation.

I was asked why information on both the satellite and sensor was required. The following quote, taken from the NASA website that describes the MODIS sensor, provides an indication of why both elements are needed: "MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (EOS AM) and Aqua (EOS PM) satellites." Thus, the same sensor (MODIS) is carried on two different satellites. Similarly, for the Ikonos satellite, we find that it "is the world's first commercial satellite able to collect black-and-white (panchromatic) images with 82-centimeter resolution and multispectral imagery with 4-meter resolution." That a single satellite carries two (or more) separate sensors is a common practice, since each sensor is designed for different applications (and therefore has different spatial / spectral / radiometric resolution capabilities).

Procedure

1. Search the web and find a remote sensing image suitable for presenting to the class. Be sure that you can also provide the required details for the image.

2. Click on the image with the right mouse button and select Save Picture As ... from the pop-up menu. Save the image to your local disk or USB flash drive.

3. Create a presentation to hand in and to use in your oral presentation.

Be sure your presentation includes:

- the image
- the image location (what area did the sensor capture?)
- URL
- satellite name
- sensor name
- sensor bands or channels used to create the image. Please provide both the spectral wavelengths and the name associated with that region; e.g., 0.63-0.69 um (red).
- image acquisition date
- your name
- the descriptions of the "significance" of the image for physical geography and human geography.

You should use point form.

4. Copy your presentation to a USB drive, or onto a CD, and bring it to class.

5. After your presentation, hand in a printed copy of your presentation for marking.

There is a sign-up sheet outside of my office (Rm 209); three people maximum per class, presentations will be held throughout the term.
