Abstract: 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 RB-57/RC8 images were reduced to a common scale of 1:63,360 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 interpretations were accomplished on original NASA color infrared S190A/B and RB-57/RC8 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 that the results were derived strictly from interpretations of tones and textures on the photography. The classification scheme was a modified version ofthe U.S. Geological Survey Land Use Classification System for use with remote sensor data. The mapping units delineated from each of the data products were as follows: LANDSAT-1 MSS -5 individual level, I 2combined level I,and 8 level II; S190A -6 level I and 13 level II; S190B -6 level I, 17 level II and 1 level III; and RB-57/RC8 -6 level I, 21 level II and 5 level HE. This investigation demonstrates that for land use mapping the Skylab S190B photography compares favorably with the RC8 photography and is much superior to LANDSAT-1 MSS imagery and Skylab S190A photography. The relative utility of the multiband imagery in identifying and quantifying hydrologic factors was evaluated. The land use statistics for two small watersheds were determined and the effects of these land use factors were appraised for possible contribution to runoff potential. This appraisal indicated that basin topography and the nature of runoff may be more important factors in predicting volume of runoff from a watershed than land use factors. 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 S190B imagery is a great advantage. Thus the S190B imagery was found to be nearly ideal for detailed, regional land use mapping; 2) for evaluating volume runoff potentials the S190B imagery was found to be as useful as the RB-57/RC8 imagery; 3) where regional hydrologic surveys and land use mapping are critical requirements in urban planning and natural resource development, the S190B imagery is of great potential value.
