The National Soil DataBase

The NSDB is the set of computer readable files which contain soil, landscape, and climatic data for all of Canada. It serves as the national archive for land resources information that was collected by federal and provincial field surveys, or created by land data analysis projects. The NSDB includes GIS coverages at a variety of scales, and the characteristics of each named soil series. The principal types of NSDB data holdings (ordered by scale) are as follows: National Ecological Framework (EcoZones, EcoRegions, and EcoDistricts); Soil Map of Canada / Land Potential DataBase (LPDB); Agroecological Resource Areas (ARAs); Soil Landscapes of Canada (SLC); Canada Land Inventory (CLI); Detailed Soil Surveys.

国家土壤数据库（NSDB）是一组可由计算机读取的文件，其中包含了加拿大境内土壤、景观和气候数据。该数据库作为国家土地资源信息的国家级档案库，汇集了由联邦及省级实地调查收集或通过土地数据分析项目创建的信息。NSDB包含了不同比例尺的地理信息系统（GIS）覆盖层，以及各命名土壤系列的特征。按比例尺顺序排列，NSDB的主要数据存储类型如下：国家生态框架（生态区、生态区域和生态小区）；加拿大土壤图/土地潜力数据库（LPDB）；农业生态资源区（ARAs）；加拿大土壤景观（SLC）；加拿大土地清查（CLI）；详细土壤调查。
