Running an Intel i9 with 64GB RAM, 2TB didicated Solid State Hard drive, plenty of memory.
I'm new to drones and this was recommended software from Coptrz, whats the alternative?
Coptrz is a DJI seller, and as a good seller, he recommends the DJI product to the customer, even if the product does not meet your needs.
Since you seem to have Trimble equipment, I describe how I proceed:
-GCP acquired with Trimble+ site calibration
-Agisoft Metashape, coordinate system that adapts to your needs, aligns with GCP as described in the manual
And you will have 3D and 2D map ready.
WGS UTM is a good alternative yes, remember this is a small 20MP sensor on the M3E, quality may change depending on light/weather conditions. It's a bit overestimated to expect to have more than +/-5cm of precision.
My feeling is that you are an experienced surveyor, who wishes to improve the quality of his work thanks to new technologies, Am I right?
Unfortunately, photogrammetry and DJI products in general are not designed for high quality investigation. If you need very accurate results, your best option is still LiDAR, not DJI but RR, Yellowscan... That's a problem with DJI dealers, they don't know much and don't take the time to listen your request and to offer you the best equipment. The main goal for most of them is to squeeze the most money out of your budget.
I think you already know it but I remind you anyway, DJI sensors only give ellipsoidal altitudes. A reference geoid is needed to correct this. Metashape handles geoid .tiff .gri .ggf very well (Trimble) This is not the case with Terra.
I have no commercial link with the brands mentioned above, I simply share the brands that give me satisfaction.
