PROJECT SUMMARY

The goals of this project are to: 1) examine the effects of year-to-year climatic variation on spectral reflectance patterns of land cover types and land use practices in eastern Kansas, 2) examine in greater detail the effects of management practices on the biophysical and spectral features of grasslands in eastern Kansas; and 3) determine the most suitable combination of season(s), spectral band(s), years, and sensor(s) for discriminating among management practices (i.e., hayed, grazed, and Conservation Reserve Program) on cool and warm season grasslands. The methods used in this research can be summarized as: 1) selection and measurement of field data; 2) selection and processing of spectral data; 3) statistical analysis to determinate relationships between the spectral and field data; and 4) analysis of the effects from other factors such as precipitation, soil, temperature, etc.

Funding provided by the Kansas NASA EPSCoR Project (grant no. 12860).

This work is being conducted in cooperation with the Department of Geography at Kansas State University and the Earth Science Department at Emporia State University.
