In more ancient times the distinction between a surveyor and a civil engineer didn’t exist. In more recent times the specialisms have grown in their own right. Read about the difference between a civil engineer, a land surveyor and a civil engineering surveyor here. I will add a list of influencers for the modern era for land surveying and drone sureying in due course but if you have any suggestions for who should be on this list let us know and we can update the list accordingly.
