TAVI与地形校正后NDVI抗地形影响比较
Topographic elimination performance comparison between TAVI and NDVI after topographic correction
摘要
Abstract
In order to compare the topographic elimination performance between TAVI and topographic correction method, applying Landsat 8 OLI image data and DEM data of Lianjiang district in Fuzhou, Fujian Province, with four topographic correction models, like C correction model, SCS+C correction model, SCS correction model, Cosine correction model. From the visual analysis, mean value and standard deviation parameters of the corrected image, the correlation between the cosine of the incident angle of the sun and the correlation of each band of the image is analyzed. The optimal C calibration model was selected to calculate NDVI of the correction results. Contrast topographic elimination per-formance from several aspects, the results show that the topographic elimination performance of TAVI is better than C correction.关键词
