Research on a Satellite Remote Sensing Image Atmospheric Correction System Based on PIE Engine
Abstract: This article takes this as a starting point to outline the basic content and main characteristics of atmospheric correction, and analyzes its necessity. It discusses a satellite remote sensing image atmospheric correction system for a spatiotemporal remote sensing cloud platform (PIE Engine) from five aspects: background technology, system architecture, business process, key technology, and specific implementation, for reference.
Keywords: satellite remote sensing images; atmospheric correction; system
1 大氣校正概述
地表反射率是反映和衡量地物真實光譜特性的關(guān)鍵指標,在自然資源調(diào)查中,可為土壤含水量、植被覆蓋度等地表理化參數(shù)估算提供科學(xué)依據(jù),大氣校正作為獲取它的一種方法,操作時工作人員一般通過消除衛(wèi)星遙感影像中的輻射誤差(由大氣效應(yīng)影響產(chǎn)生)實現(xiàn)。(剩余4051字)
