National Soil Database - Detailed Soil SurveysEntry ID: CANEMRCCRSSOC
Abstract: This dataset includes a complete project/pedigree file (mandatory); standard
coverage for the soil theme (mandatory), may include hydro theme (for base
data) and annotheme (only where these data have been digitized by CLBRR); the
PAT (Polygon Attribute File) for the soil theme is extended to include the link
to other attribute files and, optionally, additional properties of the polygon
... (mandatory); a subset of the SNF (Soil Names File) and SLF (Soil Layer File)
which contains all combinations of soil-code + modifier is included as part of
the complete digital soil map for all maps except the national soils of Canada;
all ARC/INFO coverages are in geographic units or documented to be not accurate
on conversion (mandatory); all ARC/INFO coverages include AAT files to allow
feature codes to be identified.
Variables: Landscape area parameters: slope, stoniness, drainage,
rooting depth and type, watertable, mode of deposition, soil taxonomy. Layer
properties: texture, pH, organic matter content, bulk density, moisture
retention, hydraulic conductivity, electrical conductivity, calcareousness,
cation exchange capacity, base saturation.
The coverage for each province is as follows: 50% of the potential
coverage of Alberta, British Columbia, Ontario,Quebec, 60% of the potential
coverage of New Brunswick, 70% of Saskatchewan, 85% of Manitoba, 30% of
Newfoundland, 95% of Nova Scotia, 40% of the Northwest Territories and Yukon
Territory, and 100% of Prince Edward Island. Note that although a per cent of
the potential coverage is complete, this is not all in final form.
Geographic referencing of data contents: map projections for Alberta
are Stereographic and Orthophoto; map projections for British Columbia, New
Brunswick, Newfoundland, Nova Scotia, Ontario, Prince Edward Island, Quebec,
Saskatchewan and the Yukon are Universal Transverse Mercator; map projections
for Manitoba are UTM and Orthophoto; map projections for the Northwest
Territories are UTM and Lambert Conformal; map projections for Canada as a
whole are Lambert Conformal;coordinates system is Latitude/Longitude; range of
Alberta map scales is 1:31,680 to 1:126,720; range of BC, Manitoba and Nova
Scotia map scales is 1:20,000 to 1:126,720; range of New Brunswick map scales
is 1:10,000 to 1:63,360; range of Newfoundland map scales is 1:25,000 to
1:250,000; range of Northwest Territories map scales is 1:250,000 to
1:1,000,000; range of Ontario map scales is 1:10,000 to 1:250,000; Prince
Edward Island maps are either 1:10,000 or 1:75,000; range of Quebec map scales
is 1:20,000 to 1:63,360; range of Saskatchewan map scales is 1:50,000 to
1:126,720; range of Yukon map scales is 1:1,250 to 1:125,000; Canada map scale
is 1:5,000,000.This data is currently applied to maps and reports in computer
generated format (either digital or hardcopy). Where possible, routine
procedures are used to streamline operations. However, custom products are
created as required and within the constraints of resources. The data bases are
intended to be used either on their own or in conjunction with other spatial
data such as climate, land use, etc., to assess the biological productivity of
land areas; to identify areas that have actual or potential problems affecting
land use such as salinity and susceptibility to erosion, and to assess the
severity; to locate areas or parcels of land that may be suitable for
particular types of land use for more detailed investigations, and to assess
other land use and environmental quality issues.
Potential applications: anything that requires a land resource layer
(i.e., pest risk assessment, suitability/capability for agricultural crops,
drainage, suitability for septic tile fields, susceptibility to erosion,
