The Soil and Landscape Grid of Australia (SLGA) is a comprehensive dataset of soil attributes across Australia at 3 arc-second resolution (~90m pixels). The surfaces are the outcomes from modelling that describe the spatial distribution of the soil attributes using existing soil data and environmental covariates. See Viscarra Rossel et al (2015) for further details. The SLGA can be used in studies of vadose zone processes, including solute transport, groundwater and nutrient fluxes beyond the root zone, as well as a wide spectrum of ecological, hydrological, and broader environmental applications.

Each product contains six digital soil attribute maps and their upper and lower confidence limits, representing the soil attribute at six depths: 0-5cm, 5-15cm, 15-30cm, 30-60cm, 60-100cm, and 100-200cm. These depths and soil attributes are consistent with the specifications of GlobalSoilMap.

This collection has 12 images. Ten of them contain data for GSM primary soil attributes; the other two contain regolith depth and soil depth GSM attributes.

澳大利亚土壤和景观网格 (SLGA) 是澳大利亚土壤属性的综合数据集，分辨率为 3 弧秒（~90m 像素）。表面是建模的结果，使用现有的土壤数据和环境协变量描述土壤属性的空间分布。有关更多详细信息，请参阅 Viscarra Rossel 等人 (2015)。 SLGA 可用于包气带过程的研究，包括根区以外的溶质运输、地下水和养分通量，以及广泛的生态、水文和更广泛的环境应用。

每个产品包含六个数字土壤属性图及其上下置信限，代表六个深度的土壤属性：0-5cm、5-15cm、15-30cm、30-60cm、60-100cm和100-200cm。这些深度和土壤属性与 GlobalSoilMap 的规范一致。

这个集合有 12 张图片。其中十个包含 GSM 主要土壤属性的数据；另外两个包含风化层深度和土壤深度 GSM 属性。
