so ive been doing ag mapping for a couple clients now, mostly soybean and corn fields, and i started on DroneDeploy because it was just easier to get going with. automated missions, cloud processing, pretty painless. but ive been hearing a lot of people in the survey world swear by Pix4D and i honestly cant tell if thats just because its what they learned on or if theres a real technical reason.

my main thing is NDVI outputs and elevation models for drainage planning, not like super high accuracy survey-grade stuff but accurate enough that a farmer can actually make decisions from it. im flying a Phantom 4 Multispectral right now. DroneDeploy handles the multispectral processing fine i think but sometimes i look at the point clouds and wonder if im missing something.

anyone switched from one to the other and actually noticed a difference in output quality? not talking about the UI, i get that DD is cleaner, im asking about the actual data coming out the other end.

honestly for NDVI and basic drainage work DroneDeploy is probably fine. Pix4D gives you more control over the processing parameters, like you can really dig into the point cloud densification settings and tweak stuff, but that also means more rope to hang yourself with if you dont know what youre doing. i used DD for about a year before switching to Pix4D and the main reason was GCP handling and being able to export in formats my surveyor clients actually wanted. for ag clients who just want a pretty map and an NDVI layer, DD does the job.

one thing though ? if you ever start doing anything that needs to hold up to any kind of accuracy standard, even informal, you're gonna want to learn Pix4D or at least understand what the processing report is telling you. DD kind of hides all that from you which is great until its not.

i switched to Pix4Dfields specifically for ag and its actually pretty solid for that use case, its kind of a lighter version of the main Pix4D but built around the multispectral workflow. might be worth looking at that instead of comparing the two main platforms. less overwhelming than full Pix4D mapper.
