Flying Tips

  • Always fly from the highest point.
  • Make sure you have a decently sized car that can handle the tough terrain of farms and be able to get from block to block easily..
  • Make sure that there is no more than 30m elevation difference per flight.
  • Fly between 9.30am and 3.30pm. Smaller trees or vines can be flown from 9:30am. Bigger  trees to be flown closer to solar noon. Start the day and end the day with smaller trees, which reduces the possibility of shadows. Bigger trees will have larger shadows for a longer portion of the day.
  • Don’t fly when there is rolling or scattered clouds. You can fly when there is full cloud cover.
  • Make sure the DJI Drone camera is using default settings. 
  • Make sure your MicaSense camera is updated to the latest firmware. Check for the latest update here.
  • In between flights, load your data on your computer and ensure there are no defective or missing images. It is best to ensure everything is there before you leave the farm. You don’t want to get home and attempt to upload but have missing images or insufficient coverage.
  • When selecting a boundary to fly, ensure you fly with a buffer to ensure enough coverage. Either pull the blue dots out or fly with a bigger flight path. Often the MicaSense camera misses a photo when it turns.
  • We have had cases of the power plug on the MicaSense camera losing connection. We recommend securing the cable with some putty or hot glue to ensure the vibrations during flight don’t cause the camera to switch off and miss images.
  • To make sure you have enough Micasense MSP coverage from your flights, drop all the images into the AeroView uploader in the field.
  • If the boundary is a triangle please redraw the boundary as shown below:

Organising your data

  1. Offload data from both the MicaSense and Phantom every 2-3 flights onto a laptop
  2. To ensure your data looks good, have a look at the first and last images.
  3. To ensure you don't have any corrupt files, arrange the images in order of size - any photos with a size of 0kb are corrupted. 
  4. To organise the collected data, create a folder called flight 1. Within that folder, create two folders, one called MSP and one called Visual. Copy the visual images from the DJI Phantom memory card to the Visual folder and copy the Multispectral images form the MicaSense memory card to the MSP folder. Do that for every flight thereafter.
