Digital Image Processing III: Supervised Classification
Objective: In this lab, you will compute all bands’ radiance, stack
individual bands together, and classify the image (study area) using
unsurprised and supervised classification methods. Finally, you will
calculate the flooded area.
Part I: Concepts and short questions:
1. Summarize the differences between multispectral remote sensing and hyperspectral
remote sensing
2. Using a table to summarize four multispectral remote sensors and four hyperspectral
remote sensors in terms of their resolution and coverage (spatial, spectral, radiometrical,
and temporal), sensor type (whiskbroom, pushbroom, or linear and area array), and their
major applications. (if you cannot get all of those information from the text book and
from the lecture notes, you are encouraging to search those from the Internet).
3. Summarize three EOS satellites (Terra, Aqua, Aura) in terms of the launching time,
major sensors, and purposes.
Part II:
1. Preparation:
(1). Create a Lab6 directory under c:\UserData_ENVI\yourname\. Today we will use
the atmospherically corrected image that you processed in Lab4:
p27r40_July8_2002DOS.img. You do not need to copy this image from Lab4 to
Lab6, but directly open it from Lab4, while save your results to Lab6 directory.
