One meter digital elevation model generated from bare earth LiDAR points. 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.

Series of Panchromatic orthophotos for 4 reservoir areas, Duncairn, LaFleche, Moosomin, Gouverneur taken in 2005. The photos were meant to coincide at a time when the reservoirs where at high flood supply levels (FSL).

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.

The AAFC Infrastructure Flood Mapping in Saskatchewan - Contours - 50 centimetre is the LiDAR contours with an interval of 0.5m of the capture area of Saskatchewan. The contours were modeled from the ground class at a maximum vertical distance of 0.5m and a horizontal distance of 20 m. Breaklines were not used around water features therefore a uniform height of water bodies is not necessarily present if overlapping data was collected on different days. Major contours were defined every 5m and minor contours every 0.5 m

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 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.

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 LiDAR data was produced for an Agriculture and Agri-Food Canada land and water resource study. The data is required to produce high resolution DEMs to improve hydrologic and environmental resource modelling within the area.
