This magazine isn't online, but you can get it on your iPad, Kindle or Android tablet via NextIssue. The article is a pretty basic overview, with examples of using a Rite Wing Zephyr and a hexacopter along with a Canon s100 modified with the IR filter removed. But it's notable that drones are getting this kind of attention in agriculture.

Very interesting info. Currently I am doing aerial mapping for an oil palm plantation. The main objective of this operation is to count palm stand and discover vacant point. I am also using Canon S100. The resolution is about 10 cm per pixel at 300 meter altitude. We can map about 250 Ha of land in 30 to 40 minutes.
It happen that I also got a maxmax modify Canon S100. Have not try out yet. I understand that the so call ndvi obtain by the camera is relative and if we map a large area, light condition change will affect the result. May be agpixel can have a breakthrough in this area?
Pretty good article really. I agree with your comments Kevin. I believe that they would hold true here in Australia. I can see that drones will be used as a tool for agronomists / consultants rather than everyday farmers. I have tried to find software to automate the process of analyzing the photos but have come up blank. Sounds like the Agpixel program is exactly what I've been looking for. Do you have any other information on it? Are you beta testing it?
Also in the article you mentioned you mapped 640 acres in 18 minutes. Do you mind posting your process of achieving this? I wonder what accuracy the photos had? Did you use ground control points? or camera gps? Did you use photoscan to mosiac the photos? What photo overlap did you use? The article mentioned the camera took photos every 4 seconds, I wonder what airspeed and altitude you used?
Thanks in advance

Chris, ur previous avatar was good !
Hard to believe there are enough farms for an Arducopter IR mapping product to have the kind of volume it needs to be profitable.
