摘要

Remote sensing and geographical information systems are becoming valuable tools for the creation, manipulation, and analysis of environmental systems. The Reynolds Creek Experimental Station was involved in the creation of a few hydrologic models. High-resolution multispectral videography provided a means by which biophysical properties (leaf area index, percent of cover) were spatially and temporally distributed throughout a few watersheds from relationships to point frame data in the field. The high-resolution imagery was then used to reduce the effects of atmosphere and to observe the effects of scaling as imagery was analyzed from 0.3 m to 30 m. The imagery and other data were used to create vegetation, contour, aspect, and slope cover layers to be used in distributed hydrologic models. The final outputs were then placed into a geographical information system package so that it could be used for the hydrologic modeling.
