Extraction of the corn planting area based on multi-temporal HJ-1 satellite data
Crop planting area is significant to agricultural structure adjustment and regional food balance policy. Based on field investigation and spectral property analysis of corn in HJ1-CCD images, different threshold configurations are set to build decision trees and corn planting area is precisely extracted utilizing multi-temporal HJ-1 CCD images in Zhecheng county, Henan Province of China. Both statistical planting area data from government and that extracted from Landsat TM images are deployed for evaluation and the results give an accuracy of 99.36% and 91.34%, respectively. It demonstrated that HJ1-CCD images are potentially good data source for crop planting area extraction.
