GLO Landscape Classification polygons 20170324 v06

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis dataset contains polygon and line shapefiles representing the Gloucester terrestrial (both a multipart and singlepart version) and riverine Landscape Classes respectively. It also contains KMZ exports of these features.\n\n\n\nNote: This differs from previous versions in that the extent was extended to the Gloucester AE boundary (previously the extent was to the PAE) so the discontinuous river lines that weaved in and out of the PAE boundary could be wholly included.\n\n\n\nThe polygon landscape Classes are as follows.\n\n\n\nTerrestrial (polygons)\n\nForrested Wetlands\n\nFreshwater Wetlands\n\nRainforests\n\nDry sclerophyll forests\n\nWet sclerophyll forests\n\nSaline wetlands\n\n(Non-GDE) Native vegetation\n\nPlantation or production forestry\n\nDryland agriculture\n\nIrrigated agriculture\n\nIntensive uses (includes mining)\n\n\n\nNote forestry that selectively logs native forests is included in the "(Non-GDE) Native vegetation" class rather than the economic "Plantation and production foresstry" class.\n\n## **Dataset History** \n\nThe terrestrial Landscape class polygons are sourced directly from the two input polygon source datasets and clipped to the Gloucester PAE.\n\n\n\nGDE landscape classes derive directly from the source NSW OoW GDE layer's Keith Form attribute, though the "Riverine Forests" Keith form are combined with the "Forested Wetlands" LC and the "Mangrove Swamps" and "Saltmarshes" Keith Forms are combined to form the "Saline Wetlands" LC . \n\n\n\nThe remaining non-GDE terrestrial LC polygons are mainly sourced from the ACLUM catchment landuse from the PRIMARY V7 classification, and retain the source class names except that "1 Conservation and natural environments" is rename the "non-GDE Native Vegtation" LC. A further exception is the "Plantation and Production Forestry" LC. This is derived from the SECONDARY_V7 classification where:\n\n\n\n"SecondV7" = '2.2 Production forestry' OR "SecondV7" = '3.1 Plantation forestry' OR "SecondV7" = '4.1 Irrigated plantation forestry'\n\n\n\nThe Riverine LC lines are derived directly from the Rivertypes source dataset\n\n\n\nNote for the 2016 March 9 IESC Deep Dive for GLO was necessary to tease out the Keith Forms of the "non-GDE native vegetaton" Landscape class in order to generate areal statistics for endangered species habitats. These were sourced from the Greater Hunter vegetation mapping. This sub-LC differentiation is retained in this dataset\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) GLO Landscape Classification polygons 20170324 v06.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）基于多源数据集衍生而来。源数据集的相关信息详见本元数据声明中的“谱系（Lineage）”字段；该衍生数据集的生成流程则记载于本元数据声明的“历史（History）”字段中。

本数据集包含分别对应格洛斯特（Gloucester）陆地景观类（分为多部件与单部件两个版本）与河滨景观类的多边形形状文件（shapefile）与线状形状文件，同时附带上述要素的KMZ导出文件。

注意：本数据集与过往版本的区别在于，其空间范围已扩展至格洛斯特AE边界（此前范围仅覆盖PAE），借此可完整纳入曾穿梭于PAE边界内外的断续河道线状要素。

多边形景观类详情如下：
陆地景观（多边形）
森林湿地
淡水湿地
热带雨林
硬叶旱生林
硬叶湿生林
盐渍湿地
（非地下水依赖生态系统（Non-GDE））原生植被
人工林或用材林
旱地农业
灌溉农业
高强度用地（包含矿业活动用地）

注意：对原生林进行选择性采伐的林业活动，归类至“（非GDE）原生植被”类，而非经济类“人工林与用材林”。

**数据集历史**
陆地景观类多边形要素直接来源于两个输入多边形源数据集，并经裁剪至格洛斯特PAE范围。

地下水依赖生态系统（Groundwater Dependent Ecosystem，GDE）景观类要素直接来源于源数据中新南威尔士州水资源办公室（NSW Office of Water，OoW）的GDE图层的Keith Form属性字段。其中，“河滨林”Keith Form与“森林湿地”景观类（Landscape Class，LC）合并；“红树林沼泽”与“盐沼”Keith Form则合并为“盐渍湿地”景观类。

其余非GDE陆地景观类多边形要素主要来源于ACLM流域土地利用的PRIMARY V7分类数据集，保留源分类名称，仅将“1 保护与自然环境”重命名为“非GDE原生植被”景观类。另一项例外为“人工林与用材林”景观类，其来源于SECONDARY_V7分类数据集，分类规则如下：
当`SecondV7`字段值为`2.2 用材林`、`3.1 人工林`或`4.1 灌溉人工林`时，即归入此类。

河滨景观类线状要素直接来源于Rivertypes源数据集。

注意：为获取濒危物种栖息地的面积统计数据，需针对“非GDE原生植被”景观类的Keith Form进行细分，此项工作于2016年3月9日GLO项目IESC深度研讨中完成，细分数据来源于大亨特（Greater Hunter）植被制图数据集，本次数据集保留了该子景观类的细分结果。
