Type Raster Dataset
The Red River Valley digital elevation model (DEM) was derived from airborne LiDAR data. The DEM can be used to generate contours. DEM data can be used in a GIS environment.
The data provided is a DEM covering 3800 square-kilometres of the Red River Valley in Manitoba. DEM files were generated at 1-metre resolution from LiDAR points classified as ground points. The DEM is a 32-bit floating point raster in geotiff format, in the horizontal coordinate system of NAD 1983 CSRS UTM Zone 14N and the vertical coordinate system of CGVD28.

LiDAR was acquired by Leica ALS70 HP and Reigl 780i at a point density of 3 points per square metre. DEM tiles were created at 1m resolution
Accuracy value is based on the aggregate error inherent in the production process.
LiDAR was acquired by Leica ALS70 HP and Reigl 780i at a point density of 3 points per square metre. DEM tiles were created at 1m resolution.
Accuracy value is based on the aggregate error inherent in the production process. Vertical accuracy is based on hard flat surfaces.
LiDAR data was acquired on Nov 3, Nov 4, Nov 5 and Dec 3, 2020. LiDAR data was calibrated and classified. The classified data was used to create the DEM using the following classes: 2 (ground). The DEM was created at 1-metre resolution and then exported as a geotiff with 32 bit floating elevations.
