    This layer represents Land use polygons as determined by a combination of analytic techniques, mostly using Landsat 5 image mosaics . BTM 1 was done on a federal satellite image base that was only accurate to about 250m. The images were geo-corrected, not ortho-corrected, so there is distortion in areas of high relief. This is not a multipart feature

    Fraction of absorbed photosynthetically active radiation (fAPAR) quantified the absorbed by green foliage. fAPAR has been identified by the Global Climate Observing System as an essential climate variable required for ecosystem, weather and climate modelling and monitoring. This product consists of a national scale coverage (Canada) of monthly maps of fAPAR during a growing season (May-June-July-August-September) at 20m resolution. References: L. Brown, R. Fernandes, N.

    Each pixel value corresponds to the day-of-week (1-7) from which the Weekly Best-Quality NDVI retrieval is obtained (1 = Monday, 7 = Sunday).

  • Categories  

    Each pixel value corresponds to the mean historical “Best-quality” Max-NDVI value for a given week, as calculated from the previous 20 years in the MODIS historical record (i.e. does not include data from the current year). These data are also often referred to as “weekly baselines” or “weekly normals”.

    The Saskatchewan Digital Land Cover was created to be used in the interim. The National Land Cover Project plans to integrate land cover information compiled by Natural Resources Canada, Canadian Forest Service, and Agriculture and Agri-Food Canada. The Saskatchewan Digital Land Cover raster provides a seamless provincial coverage of the province and was created by combining the Saskatchewan Research Council's Northern Digital Land Cover (NDLC) with the Southern Digital Land Cover (SDLC).  With exception to the SDLC's value 2 (i.e. Hay Crops) and value 3 (i.e. Native Dominant Grass Lands), the NDLC takes precedence over the SDLC in areas that the two rasters overlap because the NDLC is more current than the dated SDLC. The SDLC's values 2 and 3 were preserved because these land covers are not specifically represented in the NDLC. For the purpose of this dataset, some of the SDLC and NDLC values were reclassified to new values to reconcile varying definitions.  It should also be noted that because the NDLC's 30 x 30 metre pixels do not align with the SDLC's 30 x 30 metre pixels, this raster was snapped to the NDLC. Last, as is with the SDLC and the NDLC, the extent of this raster does not extend all of the way to the Saskatchewan boundary, specifically, the Information Services Corporation's SaskGIS Provincial Boundary dataset, in numerous areas along the west, south and southeast borders: There are gaps of up to 500 m wide of "no data" between the provincial boundary and the raster along these areas of the Saskatchewan boundary.

    Landcover dataset created for the agricultural portion of Saskatchewan. Download: here A satellite imagery classification of Southern Saskatchewan based mainly on 1994 Landsat5 imagery. Developed by the Saskatchewan Research Council after 1997. Background: A group of Provincial and Federal Agencies formed a partnership in March of 1997 to share the cost of obtaining satellite imagery and interpreting this imagery to create a landcover dataset for the agricultural portion of Saskatchewan. The partnership included Saskatchewan Research Council (SRC), Saskatchewan Agriculture and Food (SAF), Saskatchewan Crop Insurance (SCI), Saskatchewan Property Management Corporation (SPMC), Environment Canada, the Prairie Farm Rehabilitation Administration (PFRA) and Saskatchewan Environment Resource Management (SERM). The University of Regina was also involved as an 'in kind' partner providing research services in the area of land cover classifications, accuracy assessment and data conversions. The Partnership Agreement required SRC (partner doing the bulk of data processing) to provide digital files for each of 328 1:50,000 NTS map sheets. The digital files included not only raw imagery, but also one file for each map sheet where the imagery was classified into 24 landcover types. The accuracy of this classification was to be demonstrated by SRC to be at least 90 per cent correct. In addition to the data processing done by SRC, SPMC provided the necessary positional control data (road intersection coordinates) and verified the positional accuracy of the final product. The other partners provided feedback to SRC on classification errors, which improved the overall accuracy of the final product.

    Topographic maps produced by Natural Resources Canada conform to the National Topographic System (NTS) of Canada. Indexes are available in three standard scales: 1:1,000,000, 1:250,000 and 1:50,000. The area covered by a given mapsheet is determined by its latitude and longitude. 1:1,000,000 mapsheets are identified by a combination of three numbers (e.g. 098). 1:250,000 mapsheets are identified by a combination of numbers, and letters ranging from A through P (e.g. 098C). Sixteen smaller segments (1 to 16) form blocks used for 1:50,000 mapping (e.g. 098C03).
