基于RS与GIS技术的变更图斑自动识别方法研究

基于RS与GIS技术的土地利用变更图斑自动识别方法,即"以遥感正射影像图为基础,以地理信息和地物反射光谱为判别依据"的变更信息识别方法,能够尽量避免传统利用遥感影像分类技术进行地物变更识别存在的不足。本文通过对距离算法的改良,有效利用遥感数据的实时性和丰富性,在地理信息系统的支持下,提高了对地物变更地块的识别精度。

Research on automatically landuse change plot recognition based on RS and GIS

Based on the technology of RS and GIS,which uses orthophotomap as basis,geo-information and object reflex spectrum as judgment standard,we can automatically identify the landuse change plot.With this method,the disadvantages of traditional Remote Sensing technique can be avoided.In this sense,this article puts forward a method to improve the precision of judgment by improving arithmetic on the Mars distance and with the hel Pof both GIS and RS.
