| 摘 要： | 以SPOT510m多光谱高分辨率影像为数据基础,建立东沙岛地物信息提取的时空属性和地学规律等先验知识,在此基础上选取地物样本,并进行东沙岛地物光谱分析,从而进行东沙岛的融合信息分析,减少信息提取的误差,使解译的精度提高,结果表明,以先验知识为基础选取的样本光谱能够较好地反映地物光谱的信息含量;高分辨率影像能反映东沙岛的地物特征,并且在影像上能够反应东沙岛潟湖、口门等的发育状态,有效地揭示了地物的区分和地貌发育特征.以此进行的分类结果具有合理性;Kappa分析的分类精度达78.33%.

| Abstract: | Information extraction and geographic law knowledge were established based on SPOT5 10m multi-bands high resolution images.In order to reduce error of the information extraction and to improve interpreting precision,a spectral analysis for the choosed samples,and a fuse information analysis were made.The results show that(1) the samples based on fuse information can indicate spectral information,(2)high resolution images make Dongsha Island characteristics clear and siow lagoons,and sea mouth developed states.and(3)the fuse information of high resolution images can clearly show land use type. On the basis of the Kappa analysis,the error of the method reaches 78.33%.,which can indicate Dongsha Island land use well. |
