Land units of the Gippsland region of Victoria

A spatial dataset of soil and landform classification in Gippsland. The map units are broad `packages' of land - divided primarily on the basis of soil type, landform pattern and geology. It contains soil and land information at a scale of 1:100 000 for all land in the region.\n\nThe dataset has been derived from a combination of past studies and has been collated primarily by Ian Sargeant and Mark Imhof from 1994 to 2013. Data from older surveys have also been included in this consolidated dataset. Mapping in east and northern Gippsland regions is restricted to freehold lands. Webpages on Victorian Resources Online provide a description of each of the map units and indicate source studies used to define the map unit.\n\nIn June 2013 a dominant soil type was assigned to each unit (by David Rees, Mark Imhof and Ian Sargeant) to facilitate the creation of a digital soil map of Victoria. Australian Soil Classification (Order and SubOrder) have been included in the dataset's attribute table. \n\nAt the map scale of this dataset soil-landform units are not homogeneous. For each defined soil-landform unit, the number and proportion of landforms and soil types will vary. Representative sites and their associated profile properties are recorded on the Victorian Resources Online website (http://vro.depi.vic.gov.au/dpi/vro/wgregn.nsf/pages/wg_soil_detailed).\n\nImportantly it should be noted that soil attributes (for example texture, sodicity, pH) are expected to vary between acquired soil sites. As the variability of soil attributes within a map unit is difficult to predict, it is important to note that representative soils should be used as a guide only.\n\nDOI 10.4226/92/58e719aeb6e7c

吉普斯兰（Gippsland）地区土壤与地貌分类空间数据集。该数据集的制图单元为宽泛的土地组合单元，主要依据土壤类型、地貌格局与地质条件进行划分，涵盖该区域全域范围内1:10万比例尺的土壤与土地相关信息。

本数据集整合自既往多项研究成果，主要由Ian Sargeant与Mark Imhof于1994年至2013年间完成汇编。本次整合数据集亦纳入了早期勘测获取的数据。吉普斯兰东部与北部区域的制图范围仅限定于永久业权土地。维多利亚州资源在线（Victorian Resources Online）平台的相关网页对每个制图单元均有详细说明，并标注了用于定义该制图单元的源研究文献。

2013年6月，由David Rees、Mark Imhof与Ian Sargeant为每个制图单元指定了优势土壤类型，以支撑维多利亚州数字土壤图的制作。数据集的属性表中已纳入澳大利亚土壤分类系统（Australian Soil Classification）的纲（Order）与亚纲（SubOrder）信息。

本数据集对应比例尺下的土壤-地貌单元并非均质单元。对于每个已定义的土壤-地貌单元，其包含的地貌类型与土壤类型的数量及占比均存在差异。典型采样点及其相关土壤剖面属性信息已记录于维多利亚州资源在线平台的相关网页（http://vro.depi.vic.gov.au/dpi/vro/wgregn.nsf/pages/wg_soil_detailed）。

需特别说明的是，已采集的土壤采样点间的土壤属性（如质地、钠质化程度、pH值）存在差异。由于制图单元内部的土壤属性变异性难以预测，故仅可将典型土壤作为参考依据。
