FAQ

Why does it take 3-4 weeks to ship my drone system?

Every drone system is built to order and rigorously tested by flying the drone in various conditions. We also install and test the software and the workflow so that by the time we ship the system, we are confident that it will work as described.

Do I have to have radio control flying experience?

AgriDrone is an autonomous system, in other words, the drone flies itself according to a mission that is pre-planned. The only flying you will have to do is to take off, which involves raising the throttle till the drone has lifted off. Thereafter you simply press a button on the radio to enable autonomous mode, from there on the drone flies the mission by itself and then returns to its home position and lands.

How accurate is your NDVI imagery?

The imagery generated from the AgriDrone using our standard workflow has been shown to be 95% correlated with ground-based chlorophyll content measurements (see here). Our workflow involves using pixel value averaging, which alleviates bias due to reflectance variation. You can rest assured that, with the imagery you generate from the system, you are getting an accurate picture of the extant of stress among your crops.

Why don’t you use a higher resolution camera?

The small modified action cameras that we use are robust and simple to operate. They do not have the dpi and large image sizes of more expensive cameras, but they are very easy to operate and will survive a lot of abuse. The resolution is sufficient for the purpose.

Do you offer a repair/replace service for damaged drones?

Yes, we are able to repair and replace broken items on any of our AgriDrones. Repair rates are R400 per hour, excluding parts. The owner is responsible for shipping costs to and from our base here in the Cape Winelands.

Aren’t drones illegal?

Depending on your country/state, you may be required to write an exam, perform a skills test and then comply with certain restrictions such as flying below 400ft and not within a certain range of people and buildings. Please ascertain the regulations for drones within your country/state.

Will I be able to geo-reference the photomap? 

Yes, this can be done using a GIS application that is provided with the system. We explain how to do this in the AgriDrone user manual

Why can’t I just buy the drone?

The AgriDrone is a system, not just a drone. We ultimately sell a data-producing solution rather than just an air vehicle and without the laptop and software the drone cannot generate any data. However, for existing customers we will obviously be able to supply a complete replacement drone should theirs be lost somehow.
