Weston

About The Project

Full topographic survey of Weston subdivision between Rogers Rd. and Junction Rd., as well as between Dupont St. and Strachan Ave.  This survey combined GPS/Total Station surveying, aerial drone flights, and 3D laser scanning.  Some GPS/Total Station surveying was also completed off the corridor, along the West Toronto Rail Path and other adjacent areas.

3D laser scannning was completed both in the rail tunnels (Strachan Ave. and tunnel south of St. Clair), as well as at Bloor GO Station and on St. Clair Avenue at road level.  Linework and points at Bloor GO and St. Clair were digitized using Virtusurv software.  The software allows a technician in the office to create CADD linework using scan data, which can be incorporated into the final CADD deliverable.

The entire length of site was flown for an aerial drone survey, producing a Recap point cloud and ortho photos.

Services Provided

  • 3D Laser Scanning

    With scanning, we provide our clients with a fast and easy solution to gather large quantities of information with a high degree of accuracy. Using the 3D laser scanner to gather point cloud data that contains both location and RGB information makes it easy for Groma’s customers to dimension and display cross sections. Point clouds are easily imported into AutoCAD or can be dimensioned right on the web using online tools.

  • Aerial Drone Surveying

    Using unmanned fixed-wing and rotorcraft we can provide economical ways to perform aerial surveys. Our drones can be launched and sent to remote or hazardous locations to gather survey data or perform visual inspections. Using LiDAR techniques, the data can be used to provide geo-referenced results in a variety of formats.

  • GPS/Total Station

    Our field teams use Leica robotic Total Stations, Leica, Trimble, and Topcon GNSS units and Leica DNA03 digital levels to provide a wide range of services for projects of any size; includes topographical surveys, construction layout, control networks, deformation monitoring, site volume calculations, as-built surveys and much more.
