Topographic land surveyors are highly skilled and require a significant amount of training before they can become qualified as a topographic land surveyor.
To become a topographic land surveyor you must first study to be a land surveyor and then specialize. Most topographic land surveyors can perform all types of land surveys including geodetic, hydrographic and cadastral surveys.
Many colleges across the USA offer surveying and/or geomatics degrees. After completion of a degree you must then become licensed by the state in which you work. The licensing regulations vary between states, and you must be licensed in each state that you want to work.
