Establishing continuous scaling of NDVI based on fractal theory and GEOEYE-1 image

Abstract

The continuous spatial scaling model(CSSM) of NDVI based on fractal theory was proposed and implemented.Based on GEOEYE-1 image and taking NDVI as experimental object,the paper studied the availability of fractal methodology for high-resolution image,and discussed the selection of the best reasonable scale-level for establishing NDVI's CSSM.It w as concluded that the fractal methodology is suitable for high-resolution RS image.In some definite conditions,the best reasonable scale-level for establishing NDVI's CSSM exists and can be computed.For the fractal methodology,the results in the paper extended its available range of retrievals and image's resolutions.
