The’ Qu'Appelle Valley Lakes system – Topography and Imagery’ series consists of topographic and imagery data for lakes within the Qu'Appelle River Valley in central Saskatchewan. This data was collected in the fall of 2008 and consists of contour lines, shorelines, spot heights, tile index, and imagery

One meter digital elevation model generated from LiDAR point files. LiDAR Services International (LSI), a Calgary-based LiDAR company completed an airborne LiDAR survey for the Redberry Lake Biosphere Reserve (RLBR) and Agriculture and Agri-Foods Canada (AAFC) in October 2011. The project involved collection of LiDAR data for a 362.97 km2 block area, 252.77 km2 for Redberry Lake and 110.20 km2 for AAFC northwest of Saskatoon, SK.

The Agriculture and Agri-Food Canada’s LiDAR Projects dataset was created from existing spatial data. It contains the footprints (outlines) of all the LiDAR data that is openly distributed by Agriculture and Agri-Food Canada. LiDAR (Light Detection And Ranging) is a method of acquiring survey points using optical remote sensing technology. The dataset indicates basic information about the location, source and properties of the data.

One meter hillshade generated from full feature DEM. LiDAR Services International (LSI), a Calgary-based LiDAR company completed an airborne LiDAR survey for the Redberry Lake Biosphere Reserve (RLBR) and Agriculture and Agri-Foods Canada (AAFC) in October 2011.

Deliverables included: • 1 m bare earth and full feature grids in 1 km x 1 km tiles (ASCII XYZ format) • 1 m bare earth and full feature greyscale hillshades (GeoGeoTIF format) • Classified LiDAR point clouds and ASCII extractor program (LAS v1.2 format)

The AAFC Infrastructure Flood Mapping in Saskatchewan 1 meter Bare Earth DEM are the bare earth DEMs created at a 1 m interval for the capture area of Saskatchewan. The bare earth DEM elevations were derived from a TIN surface model of the combined DTM Key Point and Ground classes in the LiDAR point cloud tiles. It should be noted that the grid point elevations have been interpolated from the LiDAR points and may contain greater uncertainty depending on the amount of interpolation performed.

The AAFC Infrastructure Flood Mapping in Saskatchewan 1 meter Full Feature DEM are the full feature DEMs created at a 1 m interval for the capture area of Saskatchewan. The full feature grid point elevations were derived from the highest point in the High Vegetation class. At coordinates with no High Vegetation points the elevation of the corresponding bare earth grid point was applied.

Contour Lines generated from LiDAR data captured by McElhanney Consulting Services Ltd (MCSL). The contour lines connect points of equal elevation for the landscape covered by this project.

The AAFC Infrastructure Flood Mapping in Saskatchewan 1 meter Bare Earth Hillshade is are the bare earth hillshades created at a 1 m interval for the capture area of Saskatchewan. The bare earth hillshade images were derived from the bare earth DEM. The hillshades were created using a 315 degree sun azimuth and 45 degree sun angle.

The AAFC Infrastructure Flood Mapping in Saskatchewan 1 meter Full Feature Hillshade is are the full feature hillshades created at a 1 m interval for the capture area of Saskatchewan. The full feature hillshade images were derived from the full feature DEM. The hillshades were created using a 315 degree sun azimuth and 45 degree sun angle.
