Land surveying has existed for about as long as the idea of land ownership. However, over the years, the technology of measurement has improved drastically. The uses and specific needs for different types of surveys have also evolved.

Surveying is the measurement and mapping of land, sea and air space. Surveyors identify, document, and verify these maps and measurements. A survey map includes a very detailed depiction of boundaries, elevations, and existing features, whether natural or man-made.

Surveys are a must for infrastructure and development projects, and it's important to have a surveyor on the team for all stages of a project. During planning, surveys are used to determine the feasibility of the project. Then, during the design phase, surveys provide the basis for an accurate design and identify any potential roadblocks, keeping the project on track; during the construction phase for accurately locating project features; and during the post-construction phase by documenting the finished project.
