This looks like a great combination of systems for mapping small areas in high detail. If possible, please share your setup. Particularly the airframe and the components used, payload capacity, duration etc."
"Duds,I agree 100% with Parke's opinions on relying completely on a "blind" setup of the APM for the Zephyr. Individual Zephyrs can have different flight characteristics depending on weight, CG, servo type, control horn length etc. The…"
"We experienced behavior like this (flying off into the distance, but navigating correctly when RTL is engaged) a couple of times one day when we were flying at a site that had two tall radio/cellular masts close by, as well as a tall high tension…"
"Bret, have you verified that the APM actually engages the auto mode when you have the switches in the "auto" position? It may have something to do with the way you set up the interaction between the switches controlling different modes.…"
"Thanks for sharing your experience with video - it makes sense. A GoPro at 1080 resolution seems to work OK when looking at cattle in a grassland, but that is far removed from the challenges you face in Namibia. Maybe video will be more…"
"Joe, I used to be S Africa, and I still have many connections there, but I now live in Kansas. The tortoises are in scrubland in western Kansas that looks a lot like Karoo scrub. As Peter pointed out, the cold-blooded tortoises would…"
"Mike, I have looked at conservation drones; and I love it! Those guys have taken the bull by the horns. Still rough around the edges, but they seem to be making progress, and they are doing us all a great service by spreading the message that sUAS…"
"Joe and Peter, thanks to both of you. It makes sense that animals that do not fear raptors will not care about a raptor sized UAV in the sky. Maybe meerkats will be apprehensive until they learn to recognize the noisy bird as something that will not…"
Thank you for sharing your experience in counting wildilfe from the air. It is very useful information to many of us. I have a question about the effects of UAVs flying at low altitudes (such as 100 to 200m) on animal behavior. I assume that…"
"James, I'm glad to see you are using UAS for a PhD in agriculture. We need researchers in this field to expand and refine the applications. My academic email address is email@example.com
Keep in touch!
We use different methods depending on the level of precision and accuracy we need. Sometimes finding points in Google Earth can be good enough, such as road junctions, a recognizable rock, a tree etc. In most applications relative accuracy is…"
"Hi Merf.. I am in Iowa and AG research and analysis is a very interesting area for me. I am exploring some commercial service areas such as the vegetation stress analysis, especially once the FAA allows it.. before then my goal is to…"
"Mark, I am not aware of any sites that will give you all the information, and as you can imagine, there are many approaches to this type of analysis. We started a graduate course in sUAS Agricultural Applications this year at Kansas State University…"
Hi Merf.. I am in Iowa and AG research and analysis is a very interesting area for me. I am exploring some commercial service areas such as the vegetation stress analysis, especially once the FAA allows it.. before then my goal is to explore different areas of aerial inspection and photography. I don't envision this replacing my chief software architecture day job but I enjoy flying and using my software dev skills for AG research is a interesting cross over.
One thing I am trying to figure out is how to geo reference photos that you stitch together of a crop or anything.. so you can specify the lat/long of any given point in the stitched photo.
We use different methods depending on the level of precision and accuracy we need. Sometimes finding points in Google Earth can be good enough, such as road junctions, a recognizable rock, a tree etc. In most applications relative accuracy is more important than absolute accuracy, so you can often get useful data even if your georeferencing is not absolutely spot on. When we need a high level of precision and accuracy we place georeferenced markers made of vinyl window blind panels on the ground. The panels are white and 2" wide. You can form symbols with the panels to identify specific markers. It helps a lot in large fields of crops, where you may not have any recognizable features to differentiate images.
