微机大面积水稻遥感信息提取研究

本文探讨了大面积遥感图像的区划问题，提出了专题信息提取的最佳波段组合选择方法，实现了基于地理信息系统的遥感图像的分类，同时针对微机遥感图像处理的特点设计了一系列高效处理算法，并在无锡县水稻专题信息提取中得到了应用检验。

EXTR ACTING RICE INFORMATION IN LARGE AREA FROM REMOTE SENSED IMAGE BASED ON MICROCOMPUTER

his paper investigated the regionalization problem of remote sensedimage and generated the regionalization map using remote sensed image and otherthematic maps such as soil type and landuse etc.The paper also introduced the multi-dimension bright value overlap index to select the best bands compose,and fulfilledthe remote sensed image classification on the base of geographic information system.Finally,a rapid resample program and a fast Bayes classifier were provided,bothmethods used the computer base memory as large as possible,so they were much fastthan usual methods.All methods above were examined in the rice information extra-ction in Wuxi county,Jiangsu Province.
