Woody Extent and Foliage Projective Cover - Spot, OEH algorithm, NSW

This dataset contains maps of woody vegetation extent and woody foliage projective cover (FPC) for New South Wales at 5 metre resolution.

Woody vegetation is a key feature of our landscape and an integral part of our society. We value it because it contributes to the economy, protects the land, provides us with recreation, and gives refuge to the unique and diverse range of fauna that we regard so highly. Yet it poses a significant threat to us in times of fire and storm. So information about trees is vital for a range of business, property planning, monitoring, risk assessment, and conservation activities.

The datasets are:
Woody vegetation extent. A presence/absence map showing areas of trees and shrubs, taller than two metres, that are visible at the resolution of the imagery used in the analysis. This shows the location, extent, and density of foliage cover for stands of woody vegetation, enabling identification of small features such as trees in paddocks and scattered woodlands through to the largest expanses of forest in the State. Woody extent products contain 'bcu' in the file name.

Woody foliage projective cover (FPC). FPC is a measure of the proportion of the ground area covered by foliage (or photosynthetic tissue) held in a vertical plane and is a measure of canopy density. Woody FPC products contain 'bcv' in the file name.

Both mosaics and tiles are available, along with a shape file that identifies the location of the tiles.

本数据集包含分辨率为5米的新南威尔士州木本植被覆盖范围与木本植被叶投影盖度（Woody Foliage Projective Cover，FPC）地图。

木本植被是区域景观的核心特征，亦是人类社会不可或缺的组成部分。其不仅具有经济价值，可起到水土保护作用，还能为公众提供休闲场所，并为诸多受高度重视的独特多样野生动物提供栖息庇护。但在火灾与风暴灾害中，木本植被亦会对人类构成严重威胁。因此，树木相关信息对于各类商业活动、土地规划、环境监测、风险评估及生态保护工作而言至关重要。

本数据集包含两类产品：
1. 木本植被覆盖范围图：该存在-缺失地图标注了分析所用影像分辨率下可识别的、高度超过2米的乔木与灌木分布区域。该产品可展示木本植被群落的叶覆盖位置、范围与密度，能够识别从牧场内单棵树木、零散林地，直至本州最大连片森林的各类规模木本植被斑块。文件名包含‘bcu’标识的即为木本植被覆盖范围产品。
2. 木本植被叶投影盖度（Woody Foliage Projective Cover，FPC）：该指标指垂直平面内植被叶（或光合组织）覆盖地面面积的比例，是林冠密度的量化表征。文件名包含‘bcv’标识的即为木本植被叶投影盖度产品。

本数据集同时提供影像镶嵌图与分幅瓦片数据，并附带用于标注瓦片空间位置的形状文件（Shapefile）。
