Abstract:
In determination of cotton planted areas by using satellite images, surface coverage ratio and electromagnetic energy reflection characteristics of the plant constitute are the two most important parameters. In the study, surface covering ratio of cotton was measured every twenty day of its growing period. Using portable spectrometer compatible to LANDSAT 1, 2, 3 and 4 bands, soil and plant reflection values were measured. Considering the surface coverage ratios and reflection characteristics pixel reflection values (mixel) were calculated. Accordingly, surface coverage ratios were determined as 1-4% in April; 4-6 in May; 34% in June; 58% in July and 95% in August. Highest (maximum) reflection values, parallel to the coverage ratio were measured in July 31st and August 20th period. Mixel values and pixels that constituted the test areas in LANDSAT 7 ETM images were correlated and relations were searched. While a considerable negative relation (-0.55) was detected between radiometric measurements and the satellite image captured in May, as a result of correlations of radiometric measurements and July image a very important linear relation (0.97) was determined.
