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:

•  Enter the land system number as provided in the above example, where:
  16 = Ecoregion
  4b = Ecodistrict (LRA)
  03 = Land System number

• 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).

• enter the analyst name and date (year/month/day)

• Enter the SCA number
  Land system name

• Names are not unique across the province.

Descriptor	Definition
basin	a. A depressed area with no surface outlet.
	b. A low area in the earth's crust where sediments have accumulated.
bench	A 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.
coulee	A 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.
delta	The 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.
dunefield	Descriptive 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.
lowland	a. 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.
plain	Any 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.
upland	a. 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.
valley	a. 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).
