摘要

巴西莓对亚马逊地区的不同城市具有巨大的经济重要性。研究表明,它们的生产对几个家庭的收入构成有多大帮助。在这方面,评估其空间动态的研究对于理解产品的经济和社会价值至关重要。然而,考虑到它的大小和在森林中的分布,绘制地图是一项艰巨的任务。考虑到这些方面,本文采用高空间分辨率卫星图像对帕拉马拉霍岛地区的acaaizeiro进行了可视化解译。使用PRODES-INPE数据,结合IsoCluster和MAXVER自动分类。结果表明,ITC(单个树冠)制图具有优越性和细节性。相对于其他方法,由Kappa指数证实。然而,在acaaizeiros制图方面,自动分类缺乏准确性。

Mapeamento da palmeira de açaí (Euterpe oleracea Mart.) na floresta Amazônica utilizando imagem de satélite de alta resolução espacial
Acai (Euterpe oleracea Mart.) has enormous economic importance for different municipalities in the Amazon. Researches have shown how much their production helps in the composition of the income of several families. In this regard, studies that assess its spatial dynamics are crucial for understanding the economic and social value of the product. However, mapping is a difficult task given its size and occurrence in the forest. Considering these aspects, this paper presents a mapping of the acaizeiro, in an area Marajo Island, Para, using visual interpretation of the acaizal, in high spatial resolution satellite image. PRODES-INPE data were used, combined with the automatic classifications IsoCluster and MAXVER. The results demonstrate there is a superiority and detail in the ITC (individual tree crowns) mapping. In relation to other methods, confirmed by the Kappa index. However, there is an absence of accuracy of automatic classifications in relation to the mapping of acaizeiros.
