4DM provided spatial modeling to support Canada’s next generation weather radar network

The infrastructure of the current Canadian weather radar network is aging. As a result, it is encountering more frequent operational problems. In addition, there is a need for additional coverage, as well as a need for more advance radar systems in areas experiencing severe weather and northern regions of Canada to improve now-casting data and information. Today, Environment Canada, through Meteorological Service of Canada (MSC), maintains 31 sites across Canada and is currently undergoing a renewal project.

In support of their radar renewal activities, 4DM provided technical services and performed a needs analysis to determine coverage gap areas across Canada, and offered options and recommendations to MSC for the strategic planning and design of the next generation of their weather radar network. The project involved conducting weather radar user requirements, thematic spatial data development, and applying a multi-criteria analytical model to create a needs index to help prioritize potential new radar sites locations and modifications to the existing locations at a macro-scale

The Central Corridor Energy Group (CCEG), comprised of 14 First Nations communities, is focused on the development of power transmission and green energy projects in northwestern Ontario on behalf of its members. CCEG is interested in identifying and assessing potential corridor options for a 115kV transmission line that would connect the Red Lake transmission node to 4 Keewaytinook Okimakanak (KO) member communities in remote areas of northwestern Ontario.

4DM, in partnership with SENES Consultants Ltd., has been selected by CCEG to identify, analyze, and evaluate potential corridors from Red Lake to 4 KO First Nations member communities. 4DM is using a numerical spatial routing model to optimize a corridor path based on available data and input from CCEG as well as affected community members. The modeling is a consensus approach accounting for opportunities and constraints to determine a least impact corridor. These results will be utilized as a starting point for the environmental assessment planning.

4DM contracted to perform hyperspectral land classification to support hydrological modeling in the City of Surrey, BC

The City of Surrey acquired hyperspectral data using the Compact Airborne Spectrographic Imager (CASI) to support land surface classification for municipal transportation project and surface runoff determination, whereby hyperspectral imagery provides unique spectral signatures needed to differentiate between a variety of land covers.

4DM utilized a semi–automated process to identify the pervious (i.e. grass lawns, parks, forest, agriculture, etc.) and impervious (e.g. asphalt, concrete/gravel, etc.) areas. In conjunction with the hyperspectral imagery, a combination of available vector mapping data, orthoimagery, and processed LiDAR digital surface model was used to apply classification techniques using software tools such as LiDAR Analyst, QT Modeler, ArcGIS, and ENVI/IDL software.

4DM completed development of satellite based object motion mapping application

4DM was awarded financial support from the National Research Council of Canada’s Industrial Research Assistance Program (IRAP) to extract the speed, trajectory, position, area, and counts of moving objects (e.g. vehicles) from a single-pass high resolution satellite image for a variety of applications, such as transportation planning and coastal surveillance. The work involved translating the developed mathematical algorithms into a software application that can be interfaced with third-party software tools for future licensing. The model has been completed and validated for a selected study area using different satellite images and available traffic information achieving a speed detection of ± 5 km/h.

4DM and Synthesis Network Ltd. contracted to map the agri-food supply chain network within Ontario’s Golden Horseshoe

The Golden Horseshoe boasts rich agricultural land, a moderate climate and abundant fresh water resources. In response to this wealth of opportunities, as well as the unique challenges for agriculture in the face of rapid urban population growth, the Greater Toronto Area Agricultural Action Committee, the Region of Niagara, and the City of Hamilton in partnership with the Friends of the Greenbelt Foundation released a 10-year plan — Food and Farming: An Action Plan 2021. This action plan provides recommendations for supporting and expanding a thriving, integrated food and farming sector in the Golden Horseshoe. To ensure the implementation of this action plan, the Golden Horseshoe Food and Farming Alliance (GHFFA) was formed in 2012.

4DM and Synthesis Network Ltd. have been contracted by GHFFA to assemble an asset map of the agri-food supply chain in the Golden Horseshoe which will include producers, processors, and distributors, as well as marketing infrastructure, research centers, and service industry. The maps will assist providing GHFFA awareness of the depth of the agri-food supply chain in Golden Horseshoe and the data to conduct the economic analysis of the existing assets and identify gaps within the food and farming cluster of the region.

4DM and SENES contracted by MECC to study mitigating erosional impacts related to Adam Creek

The Lower Mattagami River Complex (LMRC) consists of four hydroelectric stations that historically have been providing base and peak electricity production for the Ontario electrical grid. As a part of this system, Adam Creek is used as a necessary spillway corridor to offset the passage of dangerous flows through the four associated generating stations for safety reasons. Unfortunately, diverting high peak volumes and velocity flows through Adam Creek has reshaped its physiography, including the Mattagami River confluence, as a result of severe erosion.

4DM and SENES were contracted by the Mattagami Extensions Coordinating Committee (MECC) to assess potential mitigative measures that could reduce the impacts to the downstream environment associated with releasing high flows into Adam Creek. Potential solutions will be qualitatively assessed and evaluated. It is anticipated that no single solution will resolve all of the existing issues, but that it will be a combination of comprehensive monitoring solutions, preventive intervention, and mitigation measures that will lead to a reduction in erosion along Adam Creek.

4DM, with SENES, was selected to identify and evaluate potential hydro electric transmission corridors from Pickle Lake to 10 CCEG member First Nations communities

The Central Corridor Energy Group (CCEG), comprised of 14 First Nations communities, is focused on the development of power transmission and green energy projects in northwestern Ontario on behalf of its members. CCEG is interested in identifying and assessing potential corridor options for a 115kV/44kV transmission line that would connect the upgraded Pickle Lake transmission node to 10 of its member communities in remote areas of northwestern Ontario.

4DM, in partnership with SENES Consultants Ltd., has been selected by CCEG to identify, analyze, and evaluate potential corridors from Pickle Lake to a preliminary group of 10 First Nations member communities. 4DM is using a numerical spatial routing model to optimize a corridor path based on available data and input from CCEG. The modeling is a consensus approach accounting for opportunities and constraints to determine a least impact corridor. These results will be utilized as a starting point for the environmental assessment planning.

4DM and Airborne Imaging awarded contract to acquire and process elevation data for TRCA hydraulic modeling projects

The accuracy of topographic data is critical as it is a determining factor in the hydraulic modeling of the flood plain extents. The flood plain line is a component of the Toronto and Region Conservation Authority (TRCA) regulation policy and must be kept current. In areas where the flood plain is difficult to map using the TRCA standard 1-D modeling approach, a more complex 2-D analysis must be used. Elevation data acquired from LiDAR and DEM sources are best suited for use with the software that the TRCA intends to use to model the selected spill zones in its jurisdiction.

4DM will be responsible for hydrologically flattening and enforcing the LiDAR elevation data acquired by Airborne Imaging that will be used by the TRCA to model selected spill zones in its jurisdiction. This post-processing is required to adjust for discrepancies and inaccuracies in the raw LiDAR data. The TRCA will use the processed LiDAR data to create a DEM for modeling purposes whereby the raw data may not adequately define the natural drainage pattern of the study area. The 4DM team will use their operational set of tools to efficiently and accurately hydrologically flattened and enforce the raw LiDAR data to properly define the downward drainage pathways and shorelines for TRCA modeling projects.

4DM, with HDR, awarded AAFC contract for dam safety classification and inundation mapping in Saskatchewan

The Water Infrastructure Division (WID) of Agriculture and Agri-Food Canada (AAFC) operates a diverse portfolio of water infrastructure in southwestern Saskatchewan, including thirty-three water storage projects. AAFC manages these reservoirs which were originally built from the 1930s to 1960s under the former Southwest Saskatchewan Water Supply System Development Program to serve as water storage and delivery systems to support irrigation. In conformity with the principles and practices of the Canadian Dam Association (CDA) Dam Safety Guidelines (2007), AAFC has commissioned a detailed consequence assessment of five of these structures, the Gouverneur, Admiral, Cadillac, Eastender, and Braddock dams, to be completed in early 2013.

4DM, in partnership with HDR, will be utilizing LiDAR data and orthophotography to support and conduct hydraulic dam breach modeling needed to determine the incremental flood inundation. The information from the modeling will be used to conduct consequence classification of the Gouverneur, Admiral, Cadillac, Eastend, and Braddock Dams as well as provide AAFC, where applicable, with inundation maps for use in for Emergency Preparedness Planning and Response activities.

4DM contracted to provides spatial modeling support for Niagara Escarpment Crossing Study Class Environmental Assessment, Sept 10, 2012

4DM, as sub-consultant to Hatch Mott MacDonald, was awarded The Niagara Escarpment Crossing Study Class Environmental Assessment.  The Region of Niagara has re-opened a Class Environmental Assessment (Class EA) to evaluate truck route alternatives across the Niagara Escarpment. In 1997 the Regions of Niagara and Hamilton-Wentworth completed a comprehensive study that sought to address the issue of heavy trucks traveling on steep grades across the Niagara Escarpment through residential areas. The purpose of this study is to review the Class EA completed in 1997 for a new or improved escarpment crossing of the area to accommodate commercial traffic, while minimizing negative impacts to residents and motorists. The project team will build on the available data and update it where necessary to complete an identification and screening of the planning alternatives, followed by the development of design concepts for the preferred alternative.4DM role is provide spatial data and cartography support as well as utilize a multi-criteria decision support spatial model to determine least impact solutions for alternative and preferred crossings.
