UAV Survey, Mapping & Inspections

When ground-based survey methods are impractical due to project size, location, terrain complexity, safety hazards or stringent timing requirements, then an aerial approach may be the solution to your problem.

Through our alliance with CASA approved Scoutaerial, and the combining of our capabilities, BJNorth Surveys have the resources, experience and expertise with using automated commercial UAV (rotary and fixed winged drones) for a wide range of  aerial surveying. mapping and asset inspection activities.

Our capability includes the use of thermal imaging, LIDAR and photogrammetry for high resolution aerial mapping and inspection with a level of accuracy that can be used to plan and engineer structural changes and developments. Our full inhouse large data analyzing capabilities ensures full protection of  client sensitive data while creating meaningful insights for our client operations.

Agricultural mapping use photogrammetry to stitch multiple photos of a large area into a single image, NDVI (Normalised Difference Vegetation Index) analytics are applied to provide a deeper view.

NDVI is a well-established, scientifically recognised process that is used to identify plant species and condition vegetation. By using sensors that enhance and improve the analytical process, we can increase the accuracy of the data and GPS tag to a high level of precision.

BJNorth UAV Aerial Mapping applications key focus areas include:

  • Stockpile mapping survey for volumes
  • Tailings dams
  • Mapping mine surfaces for volumes and production decisions
  • Asset Inspection
  • Aerial surveys and topographic mapping
  • Development mapping
  • Infrastructure mapping
  • Detailed mapping of urban, agricultural, industrial and forestry areas
  • Infrastructure corridors
  • Council surveys (roads, bridges, pipelines etc)
  • Watercourses and flooding
  • Sites with Access issues
  • Ability to capture in restricted air space
  • Disaster/Emergency/Crises mapping providing 35mm to 50mm vertical accuracy using same principles as conventional aerial mapping, utilising ground control , image overlap, GPS/RTK positioning
  • 3D mapping using digital photogrammetry tools
  • Photogrammetry for survey and mapping to ascertain measurement between objects
  • LIDAR with claimed 20mm vertical accuracy.
