摘要
在IKONOS影像图上提取草地信息试用了2种方法进行探索。
We can devise algorithm to derive city grassland information based on the high resolution image, through city shadow adjustment which need devising city vegetation classification algorithm and radiation adjustment. It increases classification accuracy.The vegetation texture classification uses vegetation character that various vegetation's textures are different. This thesis combined the texture and pixel value to classify the vegetations which have similar texture. The result revealed that the way could derive grassland from other vegetation the most exactly.
