section is fully capable of performing the necessary image processing. 
In the future, as Landsat costs rise sharply, airborne MSS imagery might become 
an attractive alternative to Landsat for some projects, in that the cost dif- 
ferential will not be as great as it is now. (For this study, the Landsat data 
cost $300; acquisition of the airborne MSS data cost $5,000.) The benefits of 
superior spatial and spectral resolution may warrant the extra expense. Whether 
airborne MSS or Landsat data are used, however, it is clear that water quality 
studies stand to benefit from the synoptic view these types of imagery car” 
provide.
