4DM, with SENES, was selected by the CCEG to identify and evaluate potential electric transmission corridors from Red Lake to 4 Keewaytinook Okimakanak 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 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.
