摘要: 为能够快速获得研究区域农业大棚空间信息,选择高分一号2 m全色/8 m多光谱影像为数据源,在地类光谱曲线的研究基础上,计算研究区域不同地类要素的形状指数,利用面向对象法对农业大棚的地理信息进行了提取,并对提取结果进行了精度验证与分析。结果表明,面向对象法提取农业大棚地理信息的精度达到87.6%,能够满足土地调查、规划等需求。

Abstract: The high score No.1 2 m full color/8 m multispectral image was selected as the data source, based on the study of the spectral curve of the study area, calculate the different land elements in the study area. The shape index was extracted by using the object-oriented method to extract the geographic information of the agricultural greenhouse, and the accuracy of the extraction result was verified and analyzed. The results showed that the accuracy of object-oriented extraction of geographic information in agricultural greenhouses reached 87.6%, which can meet the needs of land survey and planning.

Key words: agricultural greenhouse, high score satellite No.1, spectral curve, object-oriented
