Thank you so much. Really appreciate your help. I’ll certainly let you know how I get on. Such a good forum. 👍👍👍👍

Wow thanks for the quick response. I should mention that I live in Northern Ireland. I have one DRTK 3 unit acting as either base or rover. I also have access to an NTRIP subscription. Maybe not just as straight forward as I first thought. Thanks

Hi, Looking for a little advice please. I’ve been asked to carry out surveys of a site on a fortnightly basis as a trial and learning experience. I’m curious to know the most efficient way of doing this to ensure consistency in data collection for historical review. Is it as simple as setting...

This is all valued information so thank you very much. I’ll re process and set some GCPs as check points and check the results. 👍👍👍

Thanks for all the info. A great source of info!! GCP errors attached.

This is so helpful. Thank you so much for the advice. See attached for GCP data. All gathered using ntrip corrections (WGS84). Outputs in Terra set for IRENET75 (Ireland). I think my gcp data is good, judging by standard deviation figures. It’ll be something really basic I’m getting wrong I’m...

Wow, thank you for your quick response. I record Control Points with a rover using ntrip and standard deviation errors horizontally and vertically are in the 0.006m which I’m very pleased with. I then use the base station with the same ntrip corrections to fly the mission. It’s when I process...

Hi, I’m new to photogrammetry, struggling to get my head around a few things and would like some advice please. I have a Matrice 4E, a D-RTK 3 base station and access to ntrip corrections. What would be the most suitable way to incorporate all of the above to provide the most accurate...

All great info. Thanks so much. Lots to think about.

Thanks. I will try that. Will also try autofocus instead of Manual.

I think the email containing relevant info was on the memory card supplied with the drone. You should get 12 months of a free trial. Can also get 6 months free DJI Modify. Yes you can get outputs from Terra.

Hi, I’m new to photogrammetry and looking for a little advice please. Does anyone know how to get the Reprojection Error RMS below 1? I’ve processed multiple ortho and 3d maps and all come back with a Reprojection Error RMS of over 1. My Georeferencing RMSE is 0.01 consistently. Flight...
