Australian Soil Classification (ASC) soil type map of NSW

This map identifies the dominant soil types across NSW using the Australian Soils Classification (ASC) at Order level. It uses the best available soil resource mapping coverage incorporating over 55 different datasets of multiple scales across NSW. \r\n\r\nThe formal ASC classification has been slightly modified in this map to further identify 2 extra sub-classes - soils with alluvial origins in the Rudosol order and soils with sodium-rich subsoils in the Kurosol order category. \r\n\r\nSoil types are representative of the dominant facet (sub-landscape) of each map unit and allocated using a lookup table system, linking a Great Soil Group classification soil type to the most appropriate Australian Soil Classification (ASC) class (see LUT table in data package). In some areas (north coast region and Cobargo area), an ASC classification has been assigned to map units directly without using a lookup system. These areas are identified in the ASC confidence map found within in the data package. While the ASC classification commonly equates to a particular GSG soil type classification, this is is not always the case and therefore ASC classifications allocated manually, will have a higher accuracy. \r\n\r\n__Online Maps:__ This dataset can be viewed using [eSPADE](http://espade.environment.nsw.gov.au/) (NSW’s soil spatial viewer), which contains a suite of soil and landscape information including soil profile data. Many of these datasets have hot-linked soil reports. An alternative viewer is the [SEED Map](https://geo.seed.nsw.gov.au/Public_Viewer/index.html?viewer=Public_Viewer&locale=en-AU); an ideal way to see what other natural resources datasets (e.g. vegetation) are available for this map area.\r\n\r\n__Reference:__ Department of Planning, Industry and Environment, 2021, _Australian Soil Classification (ASC) Soil Type map of NSW_, Version 4.5, Department of Planning, Industry and Environment, Parramatta.本地图依据澳大利亚土壤分类（Australian Soils Classification, ASC）的纲级分类标准，对新南威尔士州（New South Wales, NSW）范围内的优势土壤类型进行识别。本数据集采用当前最优的土壤资源制图覆盖范围，整合了新南威尔士州内55余种不同比例尺的数据集。 本次制图对标准ASC分类体系进行了小幅调整，额外划分出两个子类别：归属于鲁多索尔土纲（Rudosol）的冲积成因土壤，以及归属于库罗索尔土纲（Kurosol）的富钠底土土壤。 土壤类型代表了每个制图单元的优势地貌单元（亚景观，sub-landscape），并通过查找表（Look Up Table, LUT）系统完成分类赋值，将大土组（Great Soil Group, GSG）分类的土壤类型与最匹配的澳大利亚土壤分类（ASC）类别进行关联（详见数据包内的LUT表）。在部分区域（如北海岸地区与科巴戈（Cobargo）区域），无需借助查找表系统，可直接为制图单元赋予ASC分类，这些区域的相关信息可在数据包内的ASC置信度图中查看。尽管ASC分类通常与特定的GSG土壤类型分类一一对应，但实际情况并非总是如此，因此手动赋予的ASC分类具备更高的准确率。 __在线地图：__ 本数据集可通过[eSPADE](http://espade.environment.nsw.gov.au/)（新南威尔士州土壤空间可视化工具）进行查看，该平台包含一系列土壤与景观相关信息，涵盖土壤剖面数据，其中多数数据集附带热链接土壤报告。另一个可选的可视化工具为[SEED地图](https://geo.seed.nsw.gov.au/Public_Viewer/index.html?viewer=Public_Viewer&locale=en-AU)，该工具可用于查看本制图区域内可获取的其他自然资源数据集（如植被数据集），是了解此类信息的理想途径。 __参考文献：__ 规划、工业与环境部，2021年，《新南威尔士州澳大利亚土壤分类（ASC）土壤类型地图》，版本4.5，帕拉马塔，规划、工业与环境部。
