Dear allWe are developing a large-scale agriculture project in Nigeria (5,000ha) and started to use drones to survey and map topography.The intention was then to use the Digital Elevation Model for…Continue

Dear Quan Le
Thanks for adding me. I read through your very interesting discussion and found quite a lot good info. As there are lot of great UAV company in that area and the fact that I'm base in Malaysia, it is unlikely or economical for me to undertake the job there. But since I'm using very similar equipment and software as yours, I'm happy to provide any info for you.
For your requirement, I agree GCP and higher side lap, 70 % or so will be require. This is because many time the drone will grab an angle relative to the flight line due to cross wind condition and depending on the grab angle, it will reduce the overlapping. All software need sufficient data to generate accurate result.

Dear Keeyen
You are right the flying we can work with a number of providers. It is the processing especially for oil palm including looking at signs of stress that we will still need help on. Would you be able to work with us or point us to the right direction in relation to mapping and assessing growth issues of oil palm plantations?

Btw congrats on your 100km achievement. We are interested in purchasing the UAV also.

Best

Dear Quan Le
We do work with a few establish oil palm plantation here in Malaysia and Indonesia. Currently the most popular application for the drone data is palm inventory, road / drainage measurement, block area calculation ect.
As for oil palm growth issue such as nutrients deficiency or water stress, generally you can use near infra red camera such as Tetracam or Micasence to capture NIR data and generate NDVI map which may tell you the good and the bad and anything in between. Jeff also have a low cost NIR filter to be fix with any point and shoot camera. But all these may need ground calibration and ground truth data to interpret it.
Both Tetracam lite and Micasence can easily fitted to your current drone. I read somewhere that Micasence give better data.

Many thanks for your advice Keeyen - hope we can work together somehow. Could we use some of your oil palm images you put online as demonstration of capability of UAV tech?
