Hope you are well. If it helps I’m a Civil Engineer working in the UK. I would also conduct topo surveys, which ended up leading me to get a PfCO through my employer.
I wouldn’t worry so much about survey qualifications - its not like the US. They are optional, but obviously be careful in how you describe your experience and look carefully at any contract you take in if it details minimum credentials. Also its good practice to understand your accuracy so you don’t over promise and under-deliver.
You describe the image as a report. In reality what Saijin showed was a report. You could create your own version if needed but its only going to be breifly read then filed.
Your image is an AutoCAD survey shown in paperspace. In my work thats very nice (and sometimes asked for by the client to show deliverables) but as designers as well we want the vector data on model space, all rectified to the nation grid system (in our case Irish Grid). That will be copied or XREF’d in to be the base of our design. All the better if its in 3D.
My workflow would be the following;
- Plan in the office (Risk assessment & method statement to client) & flight plan
- Set out ground control with RTK rover (always record before you fly in case you have problems with specific markers)
- Fly the survey
- In the office, process with Pix4D Mapper, 1st stage
- Input GCPs & Check points, mark, then process stages 2 and 3
- For design, we use the 3d point cloud & ortho
- Import the point cloud to Cloud Compare, simply and remove noise
- Resultant point cloud to ReCap, import to Civil 3D, form existing ground surface (no filtering - already done)
- Extract levels
- Use ortho to trace linework
- Combine vector products as per your image above, plus ortho loaded in a separate drawing. Hand over.
You could use Pix4D survey or Virtual Surveyor for the last section. You might get away with a bit of trial and error with QGIS. The DXF export there has become very good.
I use Pix4D as I can gauge the accuracy of the output data. Depends what you require from it. There are probably a few jobs where I didn’t need it and could have used WebODM but there is no point getting my IT to install another program, especially at the minute.
I do keep watching WebODM and using it on my own equipment. Looking forward to the day we can dump the seriously expensive Pix4D!
