Along with flight training, it is vitally important to learn how to to conduct an aerial mission. This protocol is intended to guide the new Ecosynth User through the lengthy Data Processing Pipeline to be able to successfully create Ecosynth forestry products.

  1. First, generate a waypoint path for the copter to fly, Flight Planning
    • In the process of designing your flight plan in GIS, you should consider the placement of GCPs within the Area of Interest (AOI) if GCPs will be used.
    • Refer to this image for an example of how to set out GCPs.
  2. Prepare the field site by moving all equipment and GCPs out to the site. Set up GCPs and measure GCP coordinates using the Trimble GPS.
    • Use the flight checklist [doc / link needed] to make sure you have all of your equipment. It sucks getting to the site and realizing you forgot the cameras!
  3. Fly the mission!
    • Fly an entire mission to collect aerial photos for the Ecosynth pipeline.
    • Make sure the microSD card is properly mounted in the Hexakopter so that telemetry is recorded
  4. Extract images and telemetry
  5. Generate 3D Point Clouds with Computer Vision
  6. Georeference the point clouds
    • When possible, use both the GCP methods so that the results can be compared between the two techniques
  7. Filter point clouds
  8. Generate Point Cloud CHMs
  9. Compute point cloud summary statistics

The final result of the training work will be to generate the following georeferenced data products:

  • A raster CHM map of the acquisition
  • A raster map of point cloud density (points / m2)
  • A raster difference map of [Ecosynth CHM - LIDAR CHM]
