多源遥感影像融合技术在土地利用更新和变更调查中的应用

Application of Multi-source remote sensing image-fusion technology in update and change investigation of landuse

依据多源遥感影像融合技术的基本理论,结合新时期土地利用更新调查的原则和方法,根据地物在影像的纹理特征,探讨了多源遥感影像技术在土地利用更新和变更调查中的应用,分析比较了融合方法的特点及其实际应用.

This paper introduced the basic concept of multi-source remote sensing image-fusion technology. Combining the principles and methods of update and change investigation of land-use in the new era, and Basing on the image of the texture characteristics, we discussed the application of multi-source remote sensing image-fusion technology in update and change investigation of land-use,compared the characteristic of the those methods,and analyzed their practical application.
