Object Based Image Analysis using IDRISI (Selva Edition)
Object based image analysis is more useful another classification method to produce land cover map for landscape beside pixel based classification and manual visual classification.
There were existing some software which using this classification method, such as ENVI EX, eCognition, ERDAS [Image objective].
I have created some pages which contain simple step to processing satellite imaginary, from prepare data, segmentation, and produce land cover map with this method. My short pages about this process can be downloaded here.
It may useful
Thanks and warmest regard
