rection of image density over the area of the test site has be~n achieved by fittinq moodring 
function% Studies of soil types in the laboratory and in the ficld using various xnmrs and 
scales of resolutian have defined the role played by soil parent m a t e d  aniJ landforms High 
altitude data ar? being used tc define land use, soil me, and landform rcgims In a limited 
test area the corrected image densi:;- i3!- have been correlated with moistuxe status and the

from hydrologic studies the interpretation procedure gives regi~r~al scale land use data. soil
