As the United States expanded from the Atlantic to the Pacific, people moved over the mountains and plains into the uncharted regions of the West. They found it necessary to chart their routes and to mark property lines and borderlines by surveying and filing claims.

The need for accurate geographical measurements and precise records of those measurements has increased over the years. Surveying measurements are needed to determine the location of a trail, highway, or road; the site of a log cabin, frame house, or skyscraper; the right-of-way for water pipes, drainage ditches, and telephone lines; and for the charting of unexplored regions, bodies of water, land, and underground mines.

As a result, the demand for professional surveyors has grown and become more complex. New computerized systems are now used to map, store, and retrieve geographical data more accurately and efficiently. This new technology has not only improved the process of surveying but extended its reach as well. Surveyors can now make detailed maps of ocean floors and the moon's surface.
