The purpose of this investigation was to determine the utility of Skylab S190A and B photography for providing reservoir management information in New England. LANDSAT, Skylab S190A and S190B and RB75RC8 images were reduced to a common scale of 163,360 for a mapping base to demonstrate the extent to which the imagery could be utilized in the preparation of reconnaissance land use maps. These types of maps are required in the baseline evaluation of areas for reservoir management planning and for future environmental planning activities, i.e. permit evaluation and impact statements. Visual intepretations were accomplished on orginal NASA color infrared S190AB and RB57RC8 transparencies and a LANDSAT false color print made in-house. Ancillary data were not used during the mapping exercise to eliminate bias in the comparisons and to ensure the results were derived strictly from interpretations of tones and textures on the photography. Significant findings of this investigation were as follows 1 S190B imagery is superior to the LANDSAT MSS imagery for land use mapping and is as useful for category I and II land use mapping as the high altitude RC8 imagery. Detailed land use mapping at levels III and finer from satellite imagery requires better resolution. However, the larger areal coverage available from the S19OB imagery is a great advantage. Thus the S19OB imagery was found to be nearly ideal for detailed, regional land use mapping. 2 For evaluating volume runoff potentials the S19OB imagery was found to be as useful as the RB-57RC8 imagery.
