• Gravel Railway

        Crossing

  This video is a demonstration of Praire 3D Geoinformatics' vehicular mounted LiDAR and high definition 360 imaging for mobile mapping on unimproved and aggregate road surfaces.

  Gravel and dirt roads can be mapped to survey grade accuracy without impeding traffic flow with road closures or slow moving equipment.

  A 64 LiDAR (Laser Detection and Ranging) system is used with high accuracy GPS/GLONASS (GNSS), 360-degree Ladybug camera, Inertial Measurement Unit (IMU), and Wheel Encoders can be used to map over rough road surfaces.

     Inspection

  This video is a demonstration of Prairie 3Ds abilities, using a vehicular mounted LiDAR and high definition 360 imaging for mobile mapping on paved roads, in traffic, and underneath bridges.

  Paved roads can be mapped to survey grade accuracy without impeding traffic flow with road closures or slow moving equipment.

  A 64 LiDAR (Laser Detection and Ranging) system is used with high accuracy GPS/GLONASS (GNSS), 360-degree Ladybug camera, Inertial Measurement Unit (IMU), and Wheel Encoders can be used to map over rough road surfaces.

  The data is shown above as a colourized point cloud with three-dimensional (3D) and orthographic views as well as 360-degree virtual reality images.

          Crossing

  This video is a demonstration of Prairie 3Ds inspection abilities, a paved railway crossing was scanned at road speed. The LiDAR point cloud and high definition 360-degree images are the closely inspected and meassurments of the the site are taken.

  Paved roads and railways can be mapped to survey grade accuracy without impeding traffic flow with road closures or slow moving equipment.

•      Freeway

      Inspection

  This video shows the use of LiDAR and 360 Imaging on the Preston and Circle Drive interchange.

   This demonstration examines navigating 3D models, geomarking assets, taking measurements from both LiDAR and Imagery views, and the use of repeated scans to monitor changes in infrastructure.

•      Progress

       Tracking

  The progression of infrastructure projects and comparison of the structure to the original design can be easily completed using LiDAR scanning.

  The slider to the right displays the construction of the University of Saskatchewan Holiday Inn Express and  Staybridge Suites over multiple LiDAR scans.

        The tabs below display the capabilities of our custom multi-spectral UAVs for construction, environmental,  design, and publicity purposes.

•    Photometric

     3D Mapping

  Geo referenced UAV Imagery can be used to create terrain and surface models of areas that cannot be reached using conventional surveying.

  The aerial photometric models can be combined with ground based LiDAR for from both underneath tree canopies/ structures and from above.

  

  

  

  

•         Water

        Security

  Multi-spectral remote sensing is used to monitor relative moisture, suspended sediment, changes and relative vegetation density, and the spread and detection of invasive and obnoxious species.

   Photogrammetry is used to model watersheds and produce maps of water flow, elevations, and to monitor bank stability and erosion.

  The images below show the documentation and monitoring of a Blue Green Algae bloom in a southern Saskatchewan Lake. Multi-spectral cameras were used to clearly show the current locations of algae blooms in the water body.

  

  

  Above: Blue Green Algae (Cyanobacteria) clearly visible on Infrared (IR) images of the lake surface

  

  

  Above: Blue Green Algae (Cyanobacteria) subtle on the visual image is shown as a clear band on the Infrared Image

•    Vegetation

         Health

  High definition multi-spectral cameras allow vegetation health to by analyzed using InfraRed (IR) and Ultraviolet (UV) images.

  HD Visual imagery is also collected to aid in interpretation of Vegetation Indexes and multi-spectral images.

  Below are the different channels captured during the UAV scan (Infrared, Red, and Visual).

   Infrared and Red channels are used to produce the Normalized Density Vegetation Index (NDVI) images.

•  Infrastructure

      Inspection

  UAVs can be utilized to quickly inspect hard to reach areas including bridge piers, roof tops, antennas, and power poles.

  Our 12 Mega-Pixel aerial cameras capture small details and allow photos to be easily cropped and zoomed (as shown to the right).

  

  

  

  

  

•  Aerial Imaging

      and Video

  Our UAVs (Drones) are equipped with Ultra High Definition cameras. We are able to Capture 4K video and UHD photos using gimbal and electronically stabilized cameras.

  UAVs are ideal for real estate photography, aerial mapping, aerial panoramas, tourism photos, and publicity photos.
