[UAS] DJI drones vs American drones

[Gillan, Jeffrey Kent - (jgillan)]

Hi Brian,
I have a lot of experience surveying terrain with drones using RTK and ground control methods. I would be happy to chat with you any time about it. In general, RTK is fantastic but best referencing practices could depend on your specific application. I have recently done some drone stuff with Ann Youberg on Mt. Lemmon.

Matt,



Nice to know about the pursuit for DJI drones is continuing. Their hardware and software are really good and stand up to time well.



In addition we wonder who else is using structure-from-motion to build DEMs and what methods for georeferencing they are using. The purchase of a new drone with or without RTK and a GPS system are what is relevant to us here.



Many thanks for your help. Brian

Hey Rebecca and Brian,



Let’s ask the UAS User Group. We just bought a DJI Mavic 3 and have two other DJI drones, and agree, they’re great for the price.

Hi Matt,



This is Rebecca Beers at the AZ Geological Survey. My colleague (Brian-copied) and I are curious if the University has a recommendation on an American-made drone? We are looking to purchase a new drone for our department, but I remember an email coming out a while ago stating that the University may not allow Chinese-made drone (DJI) in the future over concerns of metadata leaks. Have you heard anything else on this? We really like our seamless functionality of DJI, but we are curious if you have found any American-made drones with similar capabilities as the DJI drones? Or has the University stepped back on the concerns of DJI metadata leaks?



Thank you, and we appreciate any guidance you have on this,

-Becky
