LiDAR mapping tools

The EICD has been working with the Province of Manitoba and the International Water Institute (IWI) to develop tools utilizing LiDAR (Light Detection and Ranging) a highly accurate elevation model collected from a plane using lasers. These tools will help prioritize conservation type project locations and assist in water management.

LiDAR was collected in the Icelandic River/Washow Bay watershed in 2011. The EICD has worked with our project partners to analyze this dataset to help provide watershed residents, resource professionals, and local, provincial and regional official’s relevant land and water information.    

The below maps and links to download the .KMZ file can be viewed using Google Earth. Each map is a layer that was built utilizing International Water Institute (IWI)/Red River Basin Decision Information Network System.  


The first step to utilizing LiDAR for water management and conservation projects is to Hydro-Condition the LiDAR data.  This refers to the process of editing the LiDAR DEM (Digital Elevation Model) to remove barriers to water when we run our simulations.  When LiDAR is flown it does not "see" a culvert underneath a driveway which causes a barrier in our water flow simulation.  These 'barriers' change the way that the simulated water flows.  This does not accurately represent real life water flow and conditions.  In order to make the simulation more accurate to real life conditions, we edit the LiDAR data using our culvert inventory, local knowledge and site visits.
