4DM awarded the project for conducting quality review and hydrological enforcement of LiDAR data acquired on the Mattagami and Abitibi River Systems for Ontario Power Generations

Ontario Power Generation is updating their base mapping using orthophotography and LiDAR data. The data sets are being used for corporate planning and to support operational needs. Additional data collection has been added to the existing project that includes 19 river systems across Ontario. 4DM is responsible for quality review of the data that involves confirming data coverage, ensuring data integrity is met and the quality meets the specifications. Another component of the project involves enforcing the natural drainage of the river system to better define the stream network and river shoreline. A set of tools developed in ArcGIS along with other LiDAR software tools are being used to conduct this process. The extent of the coverage area is approximately 600 sq km.
