摘要
传统的农作物面积统计通常采用人工统计的方法,费时费力,并且精确度不高,实时性不强。为了快速、准确地获取农作物面积,本文根据实际业务需求,充分利用遥感技术,同时结合地理信息技术,与基于PPS二阶空间抽样主法提出了一套切实可行的农作物面积遥感测量方法和流程。
Traditional statistical method of crop area is artificial, which is not only time and labor consumptive, but also low accuracy and bad real time. In order to obtain crop area lastly and accurately, the paper presents a set of practical method and processes of remote sensing measurements, based on actual needs, making use of remote sensing technology, combined with Geographic Information.
