Soil and Landscape Grid National Soil Attribute Maps - Bulk Density - Whole Earth - Release 2

This is Version 2 of the Australian Soil Bulk Density - Whole Earth product of the Soil and Landscape Grid of Australia.

It supersedes the Release 1 product that can be found at https://doi.org/10.4225/08/546EE212B0048

The map gives a modelled estimate of the spatial distribution of Bulk Density in soils across Australia.

The Soil and Landscape Grid of Australia has produced a range of digital soil attribute products. Each product contains six digital soil attribute maps, and their upper and lower confidence limits, representing the soil attribute at six depths: 0-5 cm, 5-15 cm, 15-30 cm, 30-60 cm, 60-100 cm and 100-200 cm. These depths are consistent with the specifications of the GlobalSoilMap.net project - GlobalSoilMaps.
The digital soil attribute maps are in raster format at a resolution of 3 arc sec (~90 x 90 m pixels).

本数据集为澳大利亚土壤与景观网格（Soil and Landscape Grid of Australia）出品的澳大利亚土壤容重-全土壤（Whole Earth）产品第2版。
它取代了可通过https://doi.org/10.4225/08/546EE212B0048获取的第1版产品。
本数据集附带的地图提供了澳大利亚全境土壤容重空间分布的建模估算结果。
澳大利亚土壤与景观网格已推出多套数字化土壤属性产品，每套产品包含6张数字化土壤属性地图及其上下置信限，分别对应0-5 cm、5-15 cm、15-30 cm、30-60 cm、60-100 cm及100-200 cm共6个土壤深度层级。该深度划分标准与GlobalSoilMap.net项目（GlobalSoilMaps）的规范保持一致。
本系列数字化土壤属性地图采用栅格格式，分辨率为3角秒（约90×90米像素）。
