Soil and Landscape Grid National Soil Attribute Maps - Organic Carbon (1" resolution) - Release 1

This is Version1 of the Australian Soil Organic Carbon product of the Soil and Landscape Grid of Australia at 30 m resolution.

The map gives a modeled estimate of the spatial distribution of total organic carbon 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- https://esoil.io/TERNLandscapes/Public/Pages/SLGA/Resources/GlobalSoilMap_specifications_december_2015_2.pdf. 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）发布的第1版土壤有机碳产品，空间分辨率为30米。
该图谱对澳大利亚全域土壤总有机碳的空间分布开展了建模估算。
澳大利亚土壤与景观网格已推出多款数字土壤属性产品。每款产品均包含六张数字土壤属性图及其上下置信限，分别对应6个土层深度：0-5厘米、5-15厘米、15-30厘米、30-60厘米、60-100厘米及100-200厘米。上述深度标准与GlobalSoilMap.net项目的技术规范保持一致，详见：https://esoil.io/TERNLandscapes/Public/Pages/SLGA/Resources/GlobalSoilMap_specifications_december_2015_2.pdf。该系列数字土壤属性图采用栅格格式，分辨率为3角秒（对应约90×90米的像素尺寸）。
关于澳大利亚土壤与景观网格的详细信息可通过SLGA查阅。
