Soil Survey (SL) Project Boundaries (STE_SOIL_PROJ_BOUNDARIES_SVW) contain boundaries (study areas) and attributes describing each SL project (project level metadata), and includes links to the locations of other data associated with the project (e.g., soil survey reports, polygon datasets, plotfiles, scanned maps, legends). This layer is derived from the [STE_TEI_PROJECT_BOUNDARIES_SP](https://catalogue.data.gov.bc.ca/dataset/1313fac7-2ea1-4c6b-995b-bd421b7ec3c6) layer by filtering on the PROJECT_TYPE attribute. Project types include: SOIL, TIMSOI, and SOILSW. SL Project Boundaries should be used in conjunction with [Soil Name and Layer Files](https://catalogue.data.gov.bc.ca/dataset/soil-name-and-layer-files) and [Soil Survey Polygons](https://catalogue.data.gov.bc.ca/dataset/soil-survey-spatial-view) which divide the landscape into units according to soil association, name, type, drainage, parent material, and texture. Soil datasets and resources can also be accessed through the [Soil Mapping Data Packages](http://www.env.gov.bc.ca/esd/distdata/ecosystems/Soil_Data/Soil_Data_Pkgs/) or the interactive mapping application [Soil Information Finder Tool](https://www2.gov.bc.ca/gov/content/environment/air-land-water/land/soil/soil-information-finder). **Current version**: v12 (2026-06-22)

The “Soil Landscapes of Canada V.2.2/V.3.1 - Soil Order” displays the highest (most general) level of soil classification. Within the Canadian System of Soil Classification there are ten recognized soil orders (Soil Classification Working Group 1998). This system is hierarchical (from general to specific). Soil orders are further subdivided to great groups, subgroups, families, and series.

The Prairie Soil Zones file shows the general distribution of major soil zones across the Prairie region of Canada. Soil zones (based on the Canadian System of Soil Classification) are named based on the dominant soil classification of the soils in each zone. Data extent is limited to the Agricultural Zone as defined in Soil Landscapes of Canada v 3.0 (Lefebvre et al. 2005).

Soil Survey polygons contain soils spatial and attribute information utilized by the Ministry of Environment online Soil Information Finder Tool ([SIFT](http://www2.gov.bc.ca/gov/content/environment/air-land-water/land/soil-information-finder)). The information pertains to soil survey data in the Province of British Columbia, as well as links to a variety of reports and maps. Polygons related to soil surveys can be made up of a complex of up to 3 components representing 3 different soil types. These components are aspatial and represent the amount in the polygon indicated by the PERCENT_x field for the component x. Each unique soil type has a soil name and generalized attributes such as drainage, texture and coarse fragment percent. The [Soil Name and Layer Files](https://catalogue.data.gov.bc.ca/dataset/a3bc4cd3-0f1b-4a2f-bd88-76f821756d10) can be joined and related to each of the 3 components of the Soil Survey Spatial View polygons using the SoilSymbol field in the name and layer tables and the `SOILSYM_x` fields in the Soil Survey Spatial View.

The National Ecological Framework for Canada's "Soil Development by Ecoprovince” dataset contains tables that provide soil development information for components within the ecoprovince framework polygon. It provides soil development codes and their English and French-language descriptions as well as the percentage of the polygon that the component occupies. The soil development descriptions are based on the second edition of the Canadian System of Soil Classification (Agriculture Canada Expert Committee on Soil Survey, 1987).

Get consolidated soil data mapped on a county basis in a digitally stitched and standardized product. This soil survey data was mapped by a number of soil surveyors from the 1920s to the 1990s. The product incorporates soil information from a variety of map scales. The project has brought the individual county or regional municipality surveys together to reveal inconsistencies in soil data across county boundaries. The soil complex database contains other descriptive information including: * slope class * Canada Land Inventory (CLI) ranking * stoniness * drainage class * texture

This map displays an assessment of soil erosion risk for the agricultural area of Alberta. Loss of protective residue cover through cultivation will increase the potential risk of soil erosion. The vulnerability of the soil to erosion combined with the intensity of cultivation determines the degree to which the soil may be at risk. The classes shown on the map were ranked from 0 (lowest risk) to 1 (highest risk). This resource was created in 2002 using ArcGIS.

This data series represents the volumetric soil moisture (percent saturated soil) for the surface layer (<5 cm). The data is created daily and is averaged for the ISO standard week and month. The data is produced from passive microwave satellite data collected by the Soil Moisture and Ocean Salinity (SMOS) satellite and converted to soil moisture using version 6.20 of the SMOS soil moisture processor.The data are produced by the European Space Agency and obtained under a Category 1 proposal for Level 2 soil moisture data. The data are gridded to a resolution of 0.25 degrees. Data quality flags have been applied to remove areas where rainfall is present during the acquisition, where snow cover is detected and when Radio Frequency Interference (RFI) is above an acceptable threshold.

Percent of normal soil moisture is the modelled amount of plant available water (mm) in the root zone of the soil, divided by the average amount that has historically been available on that day. This value is intended to provide users with a representation of conditions above or below normal as a percentage.Values are computed using the Versatile Soil Moisture Budget (VSMB)

Difference from normal soil moisture is the modelled amount of plant available water (mm) in the root zone of the soil, minus the average amount that has historically been available on that day. This value is intended to provide users with a representation of conditions above or below normal and by the amount of water (mm).Values are computed using the Versatile Soil Moisture Budget (VSMB)
