本文综述并阐述了利用NOAA - AVHRR数据进行亚马逊流域植被制图和监测的优势。数据主要分为两类：低空间分辨率、高时间分辨率、长时间可用性的数据和高空间分辨率、时间可用性有限的数据。对前一类数据使用情况的审查表明，这在亚马逊流域广泛土地覆盖类别的一般分类中相对成功。然而，在过去，这些一般化的分类试图尽可能地复制大陆或全球比例尺地图上的广泛分类。通过这样做，他们忽略了对数据进行仔细分析后可能发现的关于亚马逊森林地区植被活力和季节性的重要年际和年内信息。全空间分辨率NOAA - AVHRR图像在大尺度森林砍伐制图中的广泛使用…
Abstract This paper reviews and illustrates the advantages of the use of NOAA‐AVHRR data for vegetation mapping and monitoring in the Amazon Basin. The data are considered under two main categories: data of low spatial but high temporal resolution and long time period availability, and data of a higher spatial resolution but more limited temporal availability. A review of the use of the former type of data reveals that this has been relatively successful in generalised classifications of broad land cover categories in the Amazon Basin. However these generalised classifications have in the past attempted to replicate as closely as possible, broad classes represented on continental or global scale maps. By doing so they have overlooked the important inter‐ and intra‐annual information on vegetation vigour and seasonality within Amazon forest areas that may be discerned with careful analysis of the data. The widespread use of the full spatial resolution NOAA‐AVHRR imagery for large scale deforestation mappin...
