NSW Native Vegetation Extent Raster 5m v1.4

The purpose of this layer is to help discriminate native tree cover and woodlands from other terrain elements. \r\n\r\nThe NSW Native Vegetation Extent 5m Raster v1.4 was developed under the State Vegetation Type Map program (SVTM) and presents a single surface raster that combines the best available information on native vegetation extent for NSW. The surface differentiates tree cover from candidate native grasslands, water, forestry plantations and a woodland matrix from non-native areas.\r\n\r\nThe surface is built on the 2011 5m NSW Woody Vegetation Extent (Fisher et al., 2016), with updates up to 2018 (Fisher et al., 2017), with the addition of candidate native grasslands, woodlands and wetlands from the visual interpretation of high-resolution imagery (OEH, 2017). \r\n\r\nThe NSW Native Vegetation Extent 5m Raster v1.4 is an integration of five existing datasets which map candidate native vegetation and water bodies for NSW. The sourcing rules from each dataset are documented in the metadata statement at the link below.\r\n\r\nAll Koala Habitat Information Base (KHIB) datasets are available for download below under 'Dataset Relationship'\r\n\r\nFor further information on the data layers and their development, please see the [Koala Habitat Information Base Technical Guide](https://www.environment.nsw.gov.au/research-and-publications/publications-search/koala-habitat-information-base-technical-guide).\r\n本图层的核心功能为区分原生林木覆盖区、林地与其他地表要素。 新南威尔士州（New South Wales, NSW）原生植被覆盖范围5米栅格数据集v1.4是在州植被类型图项目（State Vegetation Type Map Program, SVTM）框架下开发的，该数据集整合了新南威尔士州现有最优的原生植被覆盖范围相关信息，生成单表面栅格产品。该栅格可区分林木覆盖区与候选原生草原、水体、人工用材林，并将林地基质与非原生区域划分开来。 该栅格产品以2011年发布的新南威尔士州5米木本植被覆盖范围数据集（Fisher等，2016）为基础，结合截至2018年的更新数据（Fisher等，2017），并通过高分辨率影像目视解译新增了候选原生草原、林地与湿地信息（OEH，2017）。 新南威尔士州原生植被覆盖范围5米栅格数据集v1.4整合了5套现有数据集，这些数据集用于绘制新南威尔士州的候选原生植被与水体分布图。各数据集的数据源规则已在下方链接对应的元数据说明文档中详述。 所有考拉栖息地信息库（Koala Habitat Information Base, KHIB）数据集均可在下方“数据集关联关系”板块下载。 如需了解该数据集图层及其开发过程的更多信息，请参阅《考拉栖息地信息库技术指南》（链接：https://www.environment.nsw.gov.au/research-and-publications/publications-search/koala-habitat-information-base-technical-guide）。
