Surveyors have shaped our history. Surveying tools and basic mathematical principles helped ancient Egyptians set the corners of the great pyramids.

President Thomas Jefferson commissioned Lewis and Clark to explore and survey the territories from Jefferson's great real estate deal, the Louisiana Purchase. Their extensive reports, maps, and collected data provided critical information that encouraged westward settlements.

Surveyors made sure the Union Pacific and the Central Pacific railroads met in Promontory Point, Utah, to form the first transcontinental railroad.

Surveyors helped measure the distance from earth to the moon. The first men to land on the moon placed a grouping of reflector prism - measuring tools used by surveyors. The distance measured was accurate within just a couple of feet.

When the Space Shuttle Columbia disintegrated on February 1, 2003, debris scattered over hundreds of miles across 40countries. Using high-precision GPS equipment, surveyors helped to mark the location of debris so that scientists could reconstruct the accident.

Did you know that George Washington, Thomas Jefferson, and Abraham Lincoln were all surveyors?

Surveyors have made a huge impact on our past and will continue to shape our future. Technology is rapidly changing the surveying profession. What used to take weeks or months can now be done in a single day with computerized tools. Now surveyors combine time-tested practices and high-tech proficiency.
