| Abstract: | The spectral characteristic value and the variables of NDVI, NDBI and NDWI of Landsat-7 image in Changchun were studied using the Landsat TM remote sensing image with Erdas Imagine9.2 software. The comprehensive threshold of all types of ground objects were determined based on the data of elevation and slope. The Landsat TM was classified by supervised classification and expert classification. The role of expert classification in the classification of large scale remote sensing data was evaluated. |
