The boundary is a depiction of the original Green/White Area established by Orders-in-Council dated January 26, 28 & 29, 1948 (113/48, 114/48); September 1, 1948; October 7, 1948 (1152/48) and May 2, 1949 (497/49, 498/49). The area is captured for historical purposes, to analyze the changes between the original areas and the one that exists today as the Green/White Area.

Historical Green/White Area boundary is built by selecting and putting available Source Data (described below) into an edit environment of the layer, to assemble the Geoadministrative Areas (GA) boundary. The GA boundary built uses Base Features (BF) Source Data which includes arc layers of Alberta Township System (ATS), Hydrography, Hypsography and Access. In cases where BF Source Data does not exist, Alberta Data Partnerships (ADP) Cadastral Source Data including block, lot, plan, ownership and right-of-way are used. Legal Subdivision (LSD) arcs supplied by ADP are also used. ATS data layer is considered to be the foundation by which all other Source Data should be registered with when the GA boundary layer is compiled. The Cadastral Source Data maintained by ADP is used in the hierarchy order of block, lot, plan and right-of-way; regardless which version it is. The ADP cadastral representation of ATS and Hydrography is not used. The ADP LSD arcs are used for boundary segments that are interpreted as aligning with legal subdivision lines according to the defining document, but the representation of Section, Quarter Section and Road Allowance are not allowed to be used as these lines should be derived from the BF ATS Source Data. If none of the above Source Data is available and the defining document refers a specific elevation or contour, Hypsography contour data is used. If no source arc for the particular contour or elevation exists, interpolation of the contours or elevation graphically is obtained by averaging between successive contours on either side of the range of elevation values. If the defining document describes a mountain peak, interpretation of the contours to determine the highest point of the peak is determined or in certain cases a spot height point in the Hypsography cartographic layer is used to identify the peak. If the defining document describes a boundary segment as Height-of-Land (HOL), HOL data is captured by digitization or graphical construction.
In cases if the GA boundary is described, but no Source Data is available except from a digital reference file provided by data authority, with data authority's expressed permission, arcs are copied from the digital reference file.
Segments of the boundary which adjoin to Provincial Boundary or National Park, arcs are copied from these 2 layers to define the GA boundary so that the layer does conform to these 2 key layers.
Once all the Source Data has been copied and put into the edit environment, Constructed arcs are used to close polygon in cases where a gap between 2 Source Data arcs exceeds 0.001 meters. If a gap is less than 0.001 meters, one of the Source Data is extended to close the polygon, in accordance with the Source Data edit hierarchy i.e. with the highest order of importance to the least importance which is in the order of ATS, Hydrography, Hypsography, ADP data, Access, Height-of-Land or digitized arcs and digital reference file. Spatial relationship of the boundary layer compiled is maintained with the Base Features (BF) Source data and other Source Data with the geometry of all the Source Data remains unaltered throughout the editing process. Edit tolerance is set to zero for node snap and arc snap. The GA polygons compiled have all the linework precisely closed.
Attribute tables are created according to item definition, with only one label point exists per GA polygon. Clean processes on the Source Data beyond the tolerances specified above is prohibited. Source Data is edited manually in order to maintain polygon topology using BUILD processes. After polygons are built, they are attributed according to the Base Features GA Specification table standard i.e. CODE and NAME.
