... not applicable Note 1. Built-up area data are taken from multiple sources. The 1971 built-up area is based on Canada Land Inventory: Land Use (CLI: LU) and Canada Land Use Monitoring Program (CLUMP). CLI: LU and CLUMP built-up areas that were not built-up in the AAFC Land Use, 1990 dataset were removed from the 1971 built-up data and reclassified according to their 1990 cover. To improve comparability with the other years, roads included in the 1971 core built-up area were identified and removed to produce the 1971 settled area. As the 1971 dataset did not include roads outside the core built-up area, roads were modeled by applying the ratio of roads to settled area from 1990 to the 1971 settled area. Built-up area estimates for 2011 are based on Land Use, 1990, 2000 and 2010, codes 21 (Settlement–Built-up and urban) and 25 (Roads–primary, secondary and tertiary). Return to note 1 referrer Note 2. Arable land lost to settled area is calculated by overlaying the growth in settled areas from 1971 to 2011 on the CLI: LU base layer and, for areas where the 1971 settled area was trimmed, on the area reclassified using AAFC Land Use, 1990. The following CLI: LU classes were included: cropland, improved pasture and forage crops, orchards and vineyards and horticulture. Return to note 2 referrer Note 3. Natural and semi-natural land lost to settled area is calculated by overlaying the growth in settled area from 1971 to 2011 on the CLI: LU base layer and, for areas where the 1971 settled area was trimmed, on the area reclassified using AAFC Land Use, 1990. The following CLI: LU classes were included: forest, natural pasture and rangeland, outdoor recreation areas, rock and unvegetated surfaces, open wetland and unmapped areas. Return to note 3 referrer Note 4. The balance of change row reports the change, other than arable and natural and semi-natural land lost to settled area, that occurred from 1971 to 2011. These values are determined using an accounting procedure and represent the remaining difference between the opening and closing stock. Some rounding may occur.
