5. (2 points) Assume you have a portion of a Landsat 7(ETM+) scene covering the Durham County, NC. Some pertinent information about the image includes: - Path: 16 - Row: 35 - Acquisition Date: July 27, 2002 Start Time 2002:208:15:41:26.9259374 Stop Time 2002:208:15:41:54.0019999 As the Lab\#6, you select target C and D at pixel location (323,956) and (345,916) and get the following pixel values(DN) at four different bands: 1) Examine spectral data in the table above (wavelength versus DN) for target C and D. and determine land cover type (vegetation or building) for each of them based on their spectral characteristics. State your reasoning. 2) As in Lab\#6 exercise, you calculated Gain and B values: G=0.639764B==5.1 for Band 4 and G=0.621653B=5.0 for Band 3. Instead of using ENVI software use the Gain, B value and formula you used in the Lab\# 6 to calculate the radiance for Target C and D. 3) Assume Solar Spectral Irradiances for band 3 and 4 are 1533 and 1039 watts/(meter squared * m) respectively. Instead of using ENVI software, use parameters such as solar zenith angle and formula you used in the Lab\#6 to calculate the reflectance and NDVI value for Target C and D. 5.
