I was a land surveyor in Dallas, TX in the early '80s. It is a great profession because you are outdoors getting exercise all day and you are working your mind at the same time. There is some grunt work at times but it is very challenging.
The company I worked for was called Geogram Corporation. I was a party chief with a crew of 3 - instrument man, rod man, and me the chief . Each morning we got our work order from the head honchof and headed out into the Dallas/Fortwork area. Sometimes in the city, often in the country, in deep woods, fields, etc.. performing boundary and topographic surveys. We used innovative techniques to avoid long level circuits through steep terrain. I always was challenged by trying to locate old pins, etc.. It is a very old profession - only prositution is older.
But anyway, it is a great profession. As far as salary, I have not checked lately, but I would guess that a good instrument man could make $50K easy. And party chief $70K. If you have and engineering or engineering technology degree, you can move up to management and engineering work in the office required to get the product out the door.
Its a blast, go for it
cheers
I would say the only negative aspect is that you will have to work each season of the year, including the dead of winter, which can be rough, you are always going into a fast food restaurant to warm up.
