Surveyors provide support and guidance to construction projects, big and small. 

They often use technologies such as GPS and satellite imagery to help them with their work.  There are many different specialisms within surveying including geospatial and hydrographic surveyors, land surveyors, building surveyors and quantity surveyors. All these roles require people to take accurate measurements and to be able to analyse and report on these.  They may also be required to carry out financial calculations.  They usually spend time at various outdoor locations as well as in an office.
