6. On which of the three Airborne TM Images does:

  NC CIR B/W Thermal
Vegetation looks most natural.        
Vegetation most distinguishable from the land cover type.        
Vegetation types most distinguishable from other vegetation types.        
Wetlands show up best.        
Agricultural fields show up best.        
Urban areas show up best.        
Sediment in the estuary shows up best.        
Underwater features show up the best.        

7. Compare the 1996 Color Infrared Airborne (CIRA) Image to the 1972 Color Infrared Aerial Photograph (CIRAP).

  CIRA CIRAP
Which has the best resolution (sharpest features)    
Is there a difference in vegetation appearance between the two?    
Is there a difference in appearance between Sand Bars and Flats?    

8. List two other differences that you observed between the Color Infrared Aerial

Photograph and the Color Infrared Airborne Scanner Image.
