Given the time frame, I would tend to agree with you. However, you might need to look up a job description of a land surveyor, specifically for the 18th century. It may well be that it was a specialised job, and that is why a man born in Derbyshire ended up in Wales.
Re-reading your post, you also need to discover more about him as an individual. Where he was born, etc. As you say, he may well have been from Wales himself.
