ACCURACY OF LAND-USE INTERPRETATION FROM INFRARED IMAGERY IN THE 4.5 TO 5.5 MICRON BAND

. Infrared imagery in the 4.5 to 5.5 micron wavelength band was obtained in July, 1965. Interpretation and subsequent field checking indicated that differences in agricultural land use can produce tone differences in infrared imagery and that these differences tend to be more pronounced in day than in night imagery. Differences in soil fertility and cultivation practices were observed that created significant differences in tone of a single crop. The value of first-hand field information in the area being interpreted was clearly demonstrated. Interpretation accuracies of ninety percent for separation of cultivated and noncultivated lands, ninety-five percent for recognition of alfalfa, seventy percent for corn, sixty-five percent for soybeans, and eighty-five percent for separation of wooded and non-wooded areas of noncultivated lands were achieved. Interpretation of tree species and separation of pasture and brush lands were not achieved with an accuracy of over fifty percent.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74170/1/j.1467-8306.1967.tb00610.x.pd
