| Abstract: | For the purpose of land use/land cover information extraction,we had made a study on the selected Jiangxia District of Wuhan City as the test TM remote sensing image data,together with the statistical characteristics of its information and analysis based on the optimum index factor（OIF）,especially with the study on the TM image of the best bands combining with method of spectral characteristics of the test region.The results showed that TM bands 543 of land use/land cover in the TM remote sensing image was the optimum band combination,and the composition of pseudocolor image had good visual effects,which provided land use/land cover information with some effective extraction basis. |
| Keywords: | TM image optimum band selection land use and land cover remote sensing |
