Tasmania - National Intertidal-Subtidal Benthic NISB Habitat Map (PLUS)

The NISB Habitat Map was created by the University of Tasmania for a partnership between the Department of Climate Change and the National Land and Water Resources Audit. It supports the DCC/Audit partnership by providing a nationally consistent set of the available mapping data for those habitats that occur between the approximate position of the highest astronomical tide mark (HAT) and the location of the outer limit of the photic benthic zone (approximately at the 50-70 m depth contour). This area is broadly equivalent to the 'inner' and 'mid-shelf' regions identified by Geoscience Australia. The resulting map data set forms a core component of the ECM National Habitat Map Series. The habitat classes include: coral reef, rock dominated habitat, sediment dominated habitat, mangroves, saltmarsh, seagrass, macroalgae and filter feeders (e.g. sponges), as defined in the NISB Habitat Classification Scheme. The scheme is designed to support the development of marine 'ecoregions' or bioregional subregions. Details of the scheme and the process of its development are available in National Intertidal/Subtidal Benthic (NISB) Habitat Classification Scheme Version 1 (Mount, Bricher and Newton, 2007). The NISB Habitat Map consists of two layers for each state. _NISB.shp consists of the entire available habitat mapping at a resolution finer than 1:50 000 (with a few exceptions, outlined in the data quality section below). _NISB_PLUS.shp consists of all the data in _NISB.shp along with coarser resolution data, including NVIS and OzEstuaries data. These layers were used to produce the National ECM Key Habitat Distribution Map Series 10 km and 50 km tile maps.

Note: This data is labelled as “NISB_plus”, indicating that it is the NISB Habitat layer plus other lower quality layers.

NISB生境地图（NISB Habitat Map）由塔斯马尼亚大学为气候变化部（Department of Climate Change）与国家土地与水资源审计署（National Land and Water Resources Audit）的合作项目研发。该数据集为DCC/审计署合作项目提供支撑，提供了一套全国统一的测绘数据，覆盖大致位于最高天文潮位线（Highest Astronomical Tide Mark, HAT）与透光带底栖区外边界（约50-70米等深线处）之间的各类生境。这一区域大致对应澳大利亚地质科学局（Geoscience Australia）划定的“内陆架”与“中陆架”区域。最终生成的测绘数据集构成了ECM国家生境地图系列（ECM National Habitat Map Series）的核心组成部分。生境分类包括：珊瑚礁、以岩石为主的生境、以沉积物为主的生境、红树林、盐沼、海草、大型藻类以及滤食性生物（如海绵），分类依据为NISB生境分类体系（NISB Habitat Classification Scheme）。该体系旨在支撑海洋“生态区”或生物区域亚区的划定工作。该体系及其研发细节可参阅《国家潮间带/潮下带底栖（National Intertidal/Subtidal Benthic, NISB）生境分类方案 第1版》（Mount、Bricher与Newton，2007年）。NISB生境地图为每个州设置两个图层：_NISB.shp图层包含所有分辨率优于1:50000的可用生境测绘数据（少数例外情况详见下文的数据质量章节）；_NISB_PLUS.shp图层包含_NISB.shp的全部数据，同时补充了低分辨率数据，包括NVIS与OzEstuaries数据集。上述两个图层被用于制作10公里与50公里瓦片格网的全国ECM关键生境分布地图系列。注：本数据标注为“NISB_plus”，表明其为NISB生境图层叠加其他低质量图层后的数据集。
