Natural Resource Management (NRM) areas flowing into the Great Barrier Reef Marine Park 2012 (NERP TE 13.1 eAtlas AIMS, source: Dept. Env.)

This dataset corresponds to the Natural Resource Management (NRM) Regions corresponding to river catchments neighbouring the Great Barrier Reef Marine Park. The original aim of this dataset was to show river basins that flow into the Great Barrier Reef (GBR) Marine Park, grouping them by their NRM region. The NRM region boundaries already mostly correspond to a grouping of river basin boundaries and so this regrouping of river basins was unnecessary. The NRM regions did however need some adjustments as they extend out to sea and the Cape York NRM region covers river basins on the east and west coast of Cape York and thus contains river basins that do not flow into the GBR. For this reason the Cape York NRM region was split along the Great Dividing range to remove the western catchments so that only eastern catchments were kept. In addition to this the NRM region polygons were split into the mainland and sea areas to allow this dataset to be used for easy map creation. Because of these changes the polygons in this dataset do not correspond to the NRM boundaries, but are based on the NRM boundaries.

Since 2006, NRM regions have been important in the delivery of Australian Government funding initiatives including Caring for our Country, the Natural Heritage Trust, the National Landcare Program, the Environmental Stewardship Program and the Working on Country Indigenous land and sea ranger program.

The NRM regions included in this dataset: Burnett Mary, Fitzroy, Mackay Whitsunday, Burdekin, Wet Tropics and Cape York (eastern half). Since this dataset was only including catchments neighbouring the marine park it does not include the Torres Strait NRM region and only includes the eastern half of Cape York. The NRM regions were split into mainland and sea features using the Australian Coast 100k 2004 dataset.

This dataset was created for the eAtlas and is not an authoritative source of the NRM boundaries. It should be used for research or display purposes only. It should be noted that from time to time the states and/or territories may revise their regional boundaries in accordance with local needs and therefore alterations to either the attribution or boundaries of the data may occur in the future.

This dataset was derived from River Basins 1997 (Geoscience Australia), NRM Regions 2012 (Department of Environment) and Australian Coast 100k 2004 (Geoscience Australia) datasets.

Processing:

Using ArcMap a copy of the NRM regions shapefile was made (NRM_Regions_2012_GBRMP) and editing enabled. The NRM regions of interest were selected. This selection was then inverted to select all the features we didn't want to keep. These were then deleted.

The River Basins 1997 dataset was loaded into ArcMap and a transformation was chosen to convert the ADG66 data into GDA 94. The coast was checked against the Coast 100k dataset to ensure the transformation was correct.

The Cape York NRM region was split in two by tracing the catchments along the Great Dividing range based on the River Basins 1997 (Geoscience Australia) dataset. The tip of the eastern side basin of Cape York was drawn to the boundary vertically. The western side was then selected and deleted.

The Coast 100k 2004 dataset was added and an a Definition Query was setup to only keep the mainland features ("FEAT_CODE" = 'mainland').

This was then used to split the NRM_Regions_2010_GBRMP using the Split Polygons tool from the Advanced Editing menu.

A new attribute (FEAT_CODE) was then added to the shapefile to indicate if the feature was part of the mainland ('mainland') or part of the marine boundary ('sea').

The Shape_Area attribute was renamed to SHAPE_Area by removing and recreating it. Also Leng_Units and Area_Units was added as text fields.

The Data Frame projection was changed to GDA 1994 Australia Albers equal area projection for recalculate the Shape areas and length. This was done using the Calculate Geometry tool. The The AREA_DESC attribute was removed as it no longer made sense.

The shapefile was then renamed to GBR_eAtlas_NRM_Regions_2012_GBRMP.shp.

本数据集对应毗邻大堡礁海洋公园（Great Barrier Reef Marine Park）的集水区所属的自然资源管理（Natural Resource Management, NRM）区域。本数据集的最初设计目标为展示汇入大堡礁（Great Barrier Reef, GBR）海洋公园的流域，并按其自然资源管理区域进行分组。由于自然资源管理区域的边界大体匹配流域边界的分组，因此原本的流域重新分组并无必要。但自然资源管理区域仍需进行部分调整：其一，部分区域延伸至海域；其二，约克角自然资源管理区域覆盖约克角东西两岸的集水区，其中包含未汇入大堡礁的流域。基于此，本次处理沿大分水岭（Great Dividing Range）对约克角自然资源管理区域进行拆分，移除西侧集水区，仅保留东侧集水区。此外，本数据集将自然资源管理区域的多边形要素拆分为陆域与海域范围，以方便后续地图制作。经上述调整后，本数据集的多边形要素并非完全匹配原始自然资源管理区域边界，而是基于原始边界衍生而来。

自2006年起，自然资源管理区域在澳大利亚政府多项资助计划的落地中发挥了关键作用，包括“关爱我们的国家”（Caring for our Country）、自然遗产信托基金（Natural Heritage Trust）、国家土地保育计划（National Landcare Program）、环境管理计划（Environmental Stewardship Program）以及“乡村工作”原住民海陆巡护员计划（Working on Country Indigenous land and sea ranger program）。

本数据集包含的自然资源管理区域包括：伯内特-玛丽（Burnett Mary）、菲茨罗伊（Fitzroy）、麦凯-惠森迪（Mackay Whitsunday）、伯德金（Burdekin）、湿热带（Wet Tropics）以及约克角（东部区域）。由于本数据集仅纳入毗邻大堡礁海洋公园的集水区，因此未包含托雷斯海峡自然资源管理区域，仅纳入约克角的东部区域。本数据集依托2004年澳大利亚海岸100k（Australian Coast 100k 2004）数据集，将自然资源管理区域拆分为陆域与海域要素。

本数据集专为eAtlas平台制作，并非自然资源管理区域边界的权威数据源，仅可用于研究或展示用途。需注意的是，澳大利亚各州及领地可根据本地需求不时修订其区域边界，因此本数据集的属性或边界未来可能发生变更。

本数据集源自1997年流域（River Basins 1997，澳大利亚地质调查局）、2012年自然资源管理区域（NRM Regions 2012，澳大利亚环境部）以及2004年澳大利亚海岸100k（Australian Coast 100k 2004，澳大利亚地质调查局）数据集。

处理流程：
使用ArcMap软件复制自然资源管理区域形状文件，命名为NRM_Regions_2012_GBRMP并启用编辑功能。选中目标自然资源管理区域后执行反选操作，删除所有不需要保留的要素。
将1997年流域数据集加载至ArcMap，选择坐标转换方案将澳大利亚1966大地坐标系（Australian Geodetic Datum 1966, ADG66）数据转换为澳大利亚1994地心大地坐标系（Geocentric Datum of Australia 1994, GDA94），并对照2004年澳大利亚海岸100k数据集验证坐标转换的正确性。
基于1997年流域数据集，沿大分水岭（Great Dividing Range）追踪集水区范围，将约克角自然资源管理区域拆分为两部分：垂直绘制约克角东侧流域的顶端至边界，随后选中并删除西侧部分。
添加2004年澳大利亚海岸100k数据集，设置定义查询仅保留陆域要素（"FEAT_CODE" = 'mainland'）。
依托上述陆域要素，使用高级编辑菜单中的多边形拆分工具对NRM_Regions_2010_GBRMP进行拆分。
为形状文件新增属性字段FEAT_CODE，用于标识要素属于陆域（'mainland'）还是海域边界（'sea'）。
删除并重新创建Shape_Area属性字段，将其重命名为SHAPE_Area，同时新增文本字段Leng_Units与Area_Units。
将数据框投影更改为GDA 1994澳大利亚阿尔伯斯等面积投影，通过几何计算工具重新计算形状面积与长度，删除不再适用的AREA_DESC属性字段。
将最终的形状文件重命名为GBR_eAtlas_NRM_Regions_2012_GBRMP.shp。
