I have been in the surveying profession for 30 years and to my amazement I read that it is classified under D.O.T. (The dictionary of occupational titles) as "light duty". As enjoyable as working in the field can be I found very little of it to be "easy".
Large boundary surveys where you pack your equipment, supplies and clear line every day for months, large construction layout projects, large lot staking projects and even topos and as builts can be extremely difficult (detailing manholes, ditch cross sections etc.). I hope someday soon this classification can be updated. Surveyors work very hard to gather the information they need and everyone needs to know this. --Ed in Texas
