摘要
针对土地利用动态监测存在的问题 ,探索了充分利用了 GIS中地块边界的信息 ,提取出标准地类地块边界内的灰度特征、纹理特征和形态特征 ,提出基于这些特征建立相应的决策树和判决规则。对于任一待测地块可利用提取的特征信息通过距离判别法判断其所属地类。这种 GIS辅助下的图斑地类新识别方法的准确率较高 ,也是将遥感影像与地理信息结合起来的一种有效的手段。
This paper describes how to made full use of vector boundary information of GIS, and abstracted standard land type’s gray character, texture character, and shape character within boundary of polygon. Based on these features, the decision making tree and regulation were built. Then to any test polygon the land type can be identified based on it’s abstracted characters with the help of Distance Discriminate Analysis. This approach has higher nicety rate than other approaches. It is an effective approach to integrate geographical information and RS image information.
