MULTIDISCIPLINARY ANALYSES OF SKYLAB PHOTOGRAPHY FOR HIGHWAY ENGINEERING PURPOSES
A background of highway-related disciplines utilizing air photointerpretation is outlined, and LANDSAT-1 investigation results for geomorphology, hydrology, and vegetation damage reports are summarized. The visual aspects of SKYLAB photography, i.e. photointerpretation methodology, and multistage study and comparisons with LANDSAT imagery and conventional aerial photography were the prime means of study and data extraction. Highway-associated vegetation damage sites were limited within the study region, but significant damage areas of other types were identified. Resolution was not adequate for the delineation of small damage sites, since areal extent of damage must be extensive to be detected. A single large watershed was studied in detail, using four SKYLAB films, U-2 aircraft photography and LANDSAT imagery. Vegetation cover types and ridge line delineations were compared and relative values of media analyzed. Detailed studies of glacial landforms (geomorphology) were made of two selected areas in regions of diverse morphology. Detailed and generalized maps are included that show features identified on SKYLAB and other media. The synoptic coverage of eastern Maine revealed possible new correlation data. S190B photography was superior to S190A, and both were better than ERTS imagery for hydrologic and geomorphic studies. An appendix of film evaluations by field personnel is included. /Author/
