Abstract: In order to investigate the effect of the extraction of cultivated land and provide some information for the application of the image, by making use of the image data of Landsat8 OLI newly launched by the United States, we conduct computer correction and enhancement for the 12 Landsat8 OLI images of Shandong Province through the adoption of ENVI (a remote sensing image processing software). The study was carried out with interactive classification method by visual interpretation, supervised and unsupervised classification method to extract information of cultivated land in Shandong Province. The results showed that the combination of Band 5, 4, 3 and Band 6, 5, 2 of Landsat8 OLI data was suitable for extract information of cultivated land. The extraction accuracy was 91.8%. Landsat8 OLI data could meet the requirements of timely access to information of cultivated land in cultivated land use and management.
