Abstract:

This study is to examine the feasibility of using Chinese HJCCD remote sensing data to estimate cotton and midseason rice planting area in southern Jianghan Plain， Hubei Province Filed investigation has been done for the study Spectral property and NDVI index during the growing period analyzed on the six available HJCCD images in 2011 Threshold configurations were set to build decision trees for cotton and midseason rice planting area estimation Finally， planting area of cotton and midseason rice were extracted with decision trees method The precision testing result show that area accuracy and sample point accuracy were not less than 90% and Kappa coefficient was 0983 5 Therefore， it is concluded that cotton and midseason rice planting area could be estimated precisely as long as you can get the key HJ Satellite CCD Data during cloudless days in late May， early June， early July， late July or early August or middle of August and early October It should be able to provide scientific basis for planting structure adjustment and evaluation work of agrometeorological disaster
