LBA-ECO CD-37 Secondary Forest Biomass and Age Class, Rondonia, Brazil

This data set provides tree age, forest formation, and land cover classification maps, and estimates of landscape-level above-ground live woody biomass (AGLB) for secondary forests in Rondonia, Brazil. The Threshold Age Mapping Algorithm (TAMA) was applied to a densely spaced time series of Landsat images (1975 to 2003) to derive forest type and age classification maps. The AGLB of the secondary forest was estimated by combining the forest classification map with coincident biomass estimates from the Geoscience Laser Altimeter System (GLAS).

There are five raster images and three comma-delimited data files with this data set.

本数据集提供了罗纳尼亚巴西次生林树木年龄、森林形成以及土地覆盖分类图，并对景观尺度上的地面活木质生物量（AGLB）进行了估算。阈值年龄映射算法（TAMA）被应用于1975年至2003年间的密集时序Landsat影像，以推导出森林类型和年龄分类图。通过结合森林分类图与地质科学激光测高系统（GLAS）的同步生物质估算数据，对次生林的AGLB进行了估算。数据集包含五张栅格图像和三个以逗号分隔的文件。
