【摘要】:應(yīng)用遙感技術(shù)提取水稻種植信息是農(nóng)業(yè)遙感的重要內(nèi)容。GF-1衛(wèi)星WFV數(shù)據(jù)為農(nóng)業(yè)信息提取提供了新的途徑,面向?qū)ο蟮姆诸惙椒ㄊ沁b感解譯的重要方法。本研究以揚(yáng)州市為研究區(qū)域,基于GF-1影像WFV數(shù)據(jù),采用面向?qū)ο蟮姆诸惙椒?提取水稻種植信息,并實(shí)地調(diào)查驗(yàn)證試驗(yàn)結(jié)果,試圖探討GF-1數(shù)據(jù)面向?qū)ο蠓诸惙椒ㄔ谒痉N植信息提取中的可行性與影響提取精度的因素。結(jié)果表明,應(yīng)用GF-1數(shù)據(jù),采用面向?qū)ο蟮姆诸惙椒軌蚝芎玫赝瓿蓳P(yáng)州市水稻種植信息的提取,2016年揚(yáng)州市有水稻種植面積214 524 hm~2,總體精度達(dá)到98.5%,Kappa系數(shù)0.95,面積精度達(dá)97.5%;實(shí)地考察能夠提高提取精度,地形破碎程度越低,提取精度越高。
[Abstract]:Using remote sensing technology to extract rice planting information is an important content of agricultural remote sensing. GF-1 satellite WFV data provide a new way for agricultural information extraction. Object-oriented classification method is an important method of remote sensing interpretation. In this study, Yangzhou City was used as the research area. Based on the WFV data of GF-1 image, the information of rice planting was extracted by using the object-oriented classification method, and the results of the experiment were verified by field investigation. This paper attempts to explore the feasibility of object oriented classification of GF-1 data in rice planting information extraction and the factors affecting the extraction accuracy. The results show that the extraction of rice planting information in Yangzhou can be accomplished well by using GF-1 data and object-oriented classification method. The total precision of 214,524 hm~2, of rice planting area in Yangzhou in 2016 is 98.5%. The Kappa coefficient is 0.95and the area precision is 97.5. Field investigation can improve the extraction accuracy, the lower the degree of topographic fragmentation, the higher the extraction accuracy.
