NSW Forest Extent 2022 (UTM Zones 55 & 56)

The 2022 NSW Forest extent layer was created by the NSW DPIRD Forest Science team applying spatio-temporal analysis of the 2017-2022 National Forest and sparse woody vegetation data (Version 7.0 - 2022 Release) (Department of Climate Change, Energy, the Environment, and Water's). The data is available on data.gov.au.\r\nThe dataset was further analysed and masked to exclude non-forest areas and create a forest extent layer with a 20 percent canopy cover for the NSW UTM Zones 55 & 56. The mask layer includes various datasets such as NSW Land use 2017, State Vegetation Type map (SVTM), Land Zoning, Water body, etc. The DPIRD Plantation unit's Authorised plantation layer (current as Aug 2024) was used to characterise forest types, i.e. Native forest and Plantation.

2022年新南威尔士州（New South Wales，简称NSW）森林覆盖范围图层由新南威尔士州第一产业与区域发展部（NSW DPIRD）森林科学团队，基于澳大利亚气候变化、能源、环境与水利部发布的2017-2022年国家森林与稀疏木本植被数据（7.0版-2022发布版）开展时空分析后制作完成。该数据集可于data.gov.au平台获取。
本数据集经进一步分析与掩膜处理，剔除非森林区域，并针对新南威尔士州通用横轴墨卡托投影带（UTM Zones）55与56区域，生成冠层覆盖率为20%的森林覆盖范围图层。该掩膜图层整合了多类数据集，包括2017年新南威尔士州土地利用数据、州植被类型图（State Vegetation Type Map, SVTM）、土地区划数据、水体数据等。本次研究采用NSW DPIRD种植单元的授权种植区图层（截至2024年8月更新）对森林类型进行分类界定，具体分为原生林与人工林两类。
