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.
