Table summary
This table displays the different types of land cover and land use for Ottawa–Gatineau-Ont. part. The row headers provide information on the total land area, total built-up which is further split into settled and roads, arable and natural and semi natural lands, in 1971, 1991, 2001, and 2011. In 2011, the natural category is further split into forest, water and other. The row headers also provide information on the land cover and land use change from 1971 to 2011 for total built-up, arable, and natural and semi natural. The column headers provide information on area, in square kilometres, and percentage change for the CMA, and CMA-ecosystem. The column headers also provide information on CMA as a proportion of CMA-ecosystem as a percentage.

.. not available for a specific reference period ... not applicable Note 1. 2011 census metropolitan area (CMA) boundaries are used for all years. Total area excludes water. Return to note 1 referrer Note 2. The CMA-Ecosystem (CMA-E) combines any Soil Landscapes of Canada (SLC) polygon that is contained within or that intersects with the CMA boundary, as well as SLC polygons that are fully contained within this newly formed boundary of the CMA-E. Includes all terrestrial and water surfaces. Return to note 2 referrer Note 3. Built-up area for 1971 is based on Canada Land Inventory Land Use (CLI: LU) and Canada Land Use Monitoring Program (CLUMP), code B – Urban Built-up. 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 core built-up area were identified and removed to produce the 1971 settled area. 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. Return to note 3 referrer Note 4. Arable land area is composed of the cropland, tame or seeded pasture and summerfallow land from the Interpolated Census of Agriculture. Return to note 4 referrer Note 5. Natural and semi-natural land is the residual area remaining after subtracting built-up and arable land from the total area. Because it was calculated residually, the class also includes some homes and other buildings, particularly those located on large lots and in rural areas, since these may not be captured by satellite imagery as built-up, due in part to the resolution of the data and overlying tree canopy. Return to note 5 referrer Note 6. Built-up area estimates for 1991, 2001 and 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 6 referrer Note 7. For 2011, forest and water are broken out separately based on data from AAFC Crop Inventory, 2011 and CanVec+ respectively. Other natural and semi-natural land is a residual class calculated by subtracting all other classes from the total area. The change over time for these categories requires further validation.
