Willow Creek LiDAR DEM

Type  Raster Dataset

Tags  LiDAR, elevation, light detection and ranging, terrain, topography, DEM, Willow Creek, Icelandic River, Manitoba

Summary

The Willow Creek 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.

Description

The data provided is a DEM covering 1129 square-kilometres of the Icelandic River / Willow Creek watershed 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.
