The purpose of this section is to describe the field definitions and data capture rules in detail and to provide the data tables of allowable attribute codes. The attributes collected for Land Systems and Soil Landscape compilation is described in detail in the following sections.
 
Land Systems Data Capture

The Land Systems data is captured on the Land Systems Data Form.
 
Land system number
Land Systems are numbered to show the hierarchical classification of ecoregion, ecodistrict (LRA) and land system. The LRA (Ecodistricts) map is illustrated (Figure 4.1) and the legend is presented in Table 4.1. The Land System number has the following notation:

Field Definition:

Land System Number16.4b.03
  •  Enter the land system number as provided in the above example, where:
      16 = Ecoregion
      4b
      = Ecodistrict (LRA)
      03
      = Land System number
Attribute Coding Rules:
  • The Land System number is a concatenation of Ecoregion, Ecodistrict and the Land System Number.
  • This number will start at 1 for each Ecodistrict and end at the appropriate number of Land Systems in that given Ecodistrict.
  • Land System numbers are unique but a Land System can be composed of more than one polygon (Figure 4.2).
  • River valleys will break at the Ecoregion but will cross Ecodistricts and will be coded with a 00 (example 16.00.1).

Soil correlation area

The Soil Correlation Area (SCA) to which the Land System belongs for naming soils is identified by the SCA number (1 to 24) as defined in Alberta Soil Names, Generation 2 Users' Handbook (Alberta Soil Series Working Group 1993).

Field Definition:
SCA3

Attribute Coding Rules:
  • Enter the SCA number
    Land system name
Land System names consist of two parts; a geographic locator and a morphological descriptor (e.g. Chin Coulee or Stettler Plain).

Field Definition:

 Geographic
Locator
Morphological
Descriptor
Land System NameChinCoulee

Attribute Coding Rules:
Step 1)
Enter a Land System name that reflects a local geographic location.

Step 2)
Select a morphological descriptor from Table 4.2 .
If a morphological descriptor did not exist, the user added a new descriptor.
  • Names are not unique across the province.
Table 4.2 List of Morphological Descriptors (Bates and Jackson 1980).
DescriptorDefinition
basin a. A depressed area with no surface outlet.
b. A low area in the earth's crust where sediments have accumulated.
benchA long, narrow, relatively level or gently inclined strip or platform of land, earth or rock, bounded by steeper slopes above and below and formed by differential erosion of rocks of varying resistance or by a change of base level erosion; a small terrace or step like ledge breaking the continuity of a slope; an eroded bedrock surface between valley walls.
bottomland Low-lying, level land, usually highly fertile (the term signifies a grassy lowland formed by the deposition of alluvium along the margin of a watercourse; an alluvial plain or a flood plain; the floor of a valley.
couleeA dry or intermittent stream valley, gulch or wash of considerable extent; esp. a long steep-walled, trench like gorge or valley representing an abandoned overflow channel that temporarily carried meltwater from an ice sheet.
escarpment a. A long, more or less continuous cliff or relatively steep slope facing in one general direction, breaking the continuity of the land by separating two level or gently sloping surfaces and produced by erosion or by faulting.
b. A steep, abrupt face of rock, often presented by the highest strata in a line of cliffs and generally marking the outcrop of a resistant layer.
deltaThe low, nearly flat, alluvial tract of land at or near the mouth of a river, commonly forming a triangle or fan shaped plain of considerable area.
dunefieldDescriptive of an area with numerous low hills or banks of drifted (wind-borne) sand.
hill(s)a. A natural elevation of the land surface, rising rather prominently above the surrounding land, usually of limited extent and having a well defined outline (rounded rather than peaked or rugged) and generally considered to be less than 300m from base to summit; the distinction between hill and mountain is arbitrary and dependent upon local usage.
b. Any slightly elevated ground or other conspicuous elevation in an area of rugged relief.
c. An eminence of inferior elevation in an area of rugged relief. (d) A range or group of hills, or a region.
lowlanda. A general term for low-lying land or an extensive region of low land.
b. The low and relatively level ground of a region, in contrast with the adjacent higher country.
c. A low or level tract of land along a watercourse.
pediment Gently inclined plannate erosional surface generally veneered with fluvial gravels.
plainAny flat area, large or small, at a low elevation; specif. an extensive region of comparatively smooth and level or gently undulating land, having few or no prominent surface irregularities but sometimes having a considerable slope, and usually at a low elevation with reference to surrounding areas. A plain may be forested or bare of trees, and may be formed by deposition or by erosion.
plateau Any comparatively flat area of great extent and elevation; specif. an extensive land region elevated (more than 150-300m) above the adjacent country; it is commonly limited on at least one side by an abrupt descent, has a flat or nearly smooth surface but is often dissected by deep valleys and surmounted by high hills or mountains, and has a large part of its total surface at or near the summit level. A plateau is usually higher and has more noticeable relief than a plain.
uplanda. A general term for high land or an extensive region of high land.
b. The higher ground of a region, in contrast with a valley, plain, or other low lying land; a plateau.
c. The elevated land above the low areas along a stream or between hills; any elevated region from which rivers gather drainage.
valleya. Any low-lying land bordered by higher ground.
b. A broad area of generalized flat land extending inland for a considerable distance, drained or watered by a large river and its tributaries (example Mississippi Valley).

Surficial geology
The surficial geology of the Land System is identified using the legend modified from Shetsen (1987; 1990) (Table 4.3) which identifies age, mode of deposition, materials and surface form, and relief.

Soil Landscape Data Capture

The following points were some general guidelines for coding attributes for Soil Landscapes.

General
  • the system was designed to provide decision assist tools when coding attributes.
  • there were mandatory fields that were required to be coded as well as optional fields.
  • unique polygon identification was required.
  • the analyst entered the basic evidence for a polygon and was able to edit the data as required
  • the analyst had the option of importing data from an existing polygon and editing the data.
Soil model
  • the order of coding the basic evidence was important. The order in which soils are coded was used to generate a Soil Model.
Landscape model
  • the analyst entered an existing Landscape model or entered the data necessary to describe a landscape if a model did not exist.
Soil landscape models
  • the analyst entered basic evidence for the polygon. Based on the evidence and a set of rules a Soil
Landscape Model was automatically generated for that polygon.
 


Polygon identification

Field definition and examples:
MER
RNG
TWP
POLY#
4
16
29
5

Attribute coding rules
  • Mandatory entry.
  • Analysts ensured that the polygon identification numbers were unique.
  • Analysts coded the meridian, range, township and polygon number. Polygon numbers could not exceed 99.
Ecological setting
Field definition and examples:
Ecoregion
Ecodistrict (LRA)
Land System Number
SCA
05
5d
10
11

Attribute coding rules:
  • Mandatory entry for ecoregion, ecodistrict, Land System number and SCA (Table 4.1).
Analyst and correlator
Attribute coding rules:
  • Analyst name was a mandatory entry (automatically done).
  • For every Soil Landscape polygon coded, a record of the date and name of analyst was stored.
Soil model attributes
Attributes of the Soil Model were captured as basic evidence. The analyst captured only those pieces of evidence that were known. A set of rules were applied to the basic evidence to generate a soil model.

Attribute coding rules:
  • the basic evidence could be recorded to any level of detail to which the soil analyst was confident.
  • the soil model symbol was generated automatically
Attributes:

The analyst coded at least one of the following four attributes:
Soil Series: from Generation 2 Soil Names File
Order: According to the CSSC, Table 4.10
Great Group: According to the CSSC, from Table 4.10
Sub Group: According to the CSSC, from Table 4.10

The analyst coded:
Wetness: Table 4.5
Parent Material: from Table 4.7
Proportion:
a) Dominant (Dom) ³ 60%
b) Co-Dominant (Co-Dom) ³ 30 - £ 60%
c) Significant (Sig) ³ 10 - £ 30%
Allowable combination of proportions:
a) One dominant soil; up to five significant soils
b) Two co-dominant soils; up to four significant soils
c) Three co-dominant soils (ranked in order of occurrence; one significant soil

The analyst had the option of coding:
Modifier: A modifier of the subgroup, from Table 4.8
Variant: from Table 4.9

Landscape model attributes
Landscape models are a conceptual description of a recognizably distinct landscape. The models are used to identify the following characteristics of a landscape:
- surface form (inclined, undulating, hummocky, rolling, etc.).
- slope gradients
- slope lengths
- landform elements
- relief

Surface form can be described and classified by various methods. The most common methods are surface shape (or expression) and geologic landform (which implies method of origin). Table 4.11 illustrates the current list of Landscape Models described by surface form and landform.

Attribute coding rules:
  • Choose one model for Soil Landscape mapping by entering the appropriate code as defined in Table 4.11.
