This study assessed the value of remote sensing techniques in providing reliable, and detailed distribution patterns and area values for post-harvest ground cover conditions in the South Interlake region of Manitoba. The methodology used involved a series of stages based on a computer classification of an October 20, 1986 Landsat 5 TM image in conjunction with ancillary data on soil texture criteria and field measurements and observations collected two weeks prior. 42.14% of the study area was classified as crop residue, 63.96% of which was classified as having 33%-66% crop residue cover, 25.74% as 0%-33% crop residue cover or bare soil, and 10.3% as 67%-100% crop residue cover or stubble. The results of the classification revealed that the crop residue cover types of interest were spectrally separable, and that the information generated (t
