As a surveyor, you determine the location of legal property lines. Surveyors compile data and legal documents known as surveys for mapping or building real estate projects. You can be hired by homeowners, businesses, or government agencies to work on various types of projects, from assessing property lines for commercial construction or the sale of a private home, to providing data on where to build roads. Surveyors frequently work for engineering firms, but many also find jobs with construction companies or local governments. You may also prepare sketches, take measurements of work sites, and calculate estimates.
