Based on the research results of“feature”by neuroscience

this paper discusses the definition of“spatial feature”and its applications on targets recognition and classification in remote sensing images of high spatial resolution. The research shows spatial feature consists of two aspects: spatial original feature and spatial functional feature. The former is a reflection of the characteristic of constituent elements of spatial entity

and is for recognition of spatial entity (that means“what it is”); the latter is a functional classification indication of spatial entity (that means“what it does”). The paper also illustrates an experiment about airport recognition and classification ground on a remote sensing image of high spatial resolution.
