The soil mapping and soil site information can be used to inform a variety of decisions, including land management practices for agriculture, forestry or other uses. ecosystems, wildlife habitat characterization, water holding capacity and drainage, and others, Soil attributes include soil composition (mineral or organic), soil texture, coarse fragment content, drainage, soil layer thicknesses and characteristics, soil physical and chemical properties, as well as landform and parent material. Soil mapping is also the basis for derived or interpreted products or themes including soil capability for agriculture, erosion potential, soil suitability for urban settlement or septic field absorption capability or engineering uses, areas subject to inundation or with high water tables, and other interpretations,
Soil surveys range is age, map scale and quality. Most soil surveys were completed prior to the mid 1980's. These
maps typically show up to three soils that are known or expected to occur in each polygon. Minor amounts of other soils may also be present but could not be specifically mapped at the scale of the survey. Polygon boundaries are also approximate. Therefore, at any point on the map, it is probable that one of the mapped soils will be present, but it is not guaranteed. The likelihood that the information is accurate at any given point on the ground depends on survey
and mapping scale, as well as activities that have taken place on that point since the area was mapped (i.e., cultivation, drainage installation, erosion).

Original soil mapping would have been completed on aerial photos, manually transferred to paper topographic maps which were drafted to create published maps, and later digitized. With NAD coordinate shifts and overlay of this data on more recent topographic basemaps, polygon boundaries may be sifted relative to topographic features such as lakes and rivers; though shifts are not necessarily consistent across a mapsheet or region. Similar spatial accuracy issues exist with the BCSIS soil pit dataset.
