 这里显示的数据是通过在800m²的网格单元内汇总当前USDA-NCSS的土壤调查数据（在没有SSURGO的地方用STATSGO回填）获得的。这种数据汇总技术导致地图可能与任何特定点的原始数据不一致，其目的是在全州范围内描述土壤属性的区域趋势。

这个应用程序是由加州大学戴维斯分校的加州土壤资源实验室和加州大学ANR与美国农业部自然资源保护局合作开发的。本网站和网格化数据产品请使用以下引文。

预处理
对于具有深度剖面的图层，将创建一个具有最小深度和最大深度属性的_剖面集合，然后可用于过滤，并允许不同的剖面留在单一属性的图像集合中，例如沙和沙_剖面。

你可以在这里下载数据层，以及分类而非连续的层的查询表。同时，模式金字塔策略也适用于所有的分类图层，你可以在下载页面找到所有分类变量的查询表。
