The median annual wage of surveying and mapping technicians was $37,900 in May 2010. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $23,450, and the top 10 percent earned more than $60,870. Approximately 18 percent belonged to a union.
Surveying and mapping technicians typically work regular schedules but may have longer hours during the summer, when weather and light conditions are most suitable for fieldwork. Construction-related work may be limited during times of harsh weather.
