The Ohio Society of Professional Surveyors was incorporated in 1972 as the Professional Land Surveyors of Ohio. OSPS's more than 900 members include professional surveyors, surveyor technicians, interns, and others who work in the industry; students; and companies engaged in supplying services and equipment to the surveying profession.

The Surveyors Pledge

To give the utmost of performance.
To participate in none but honest enterprise.
To live and work according to the laws of man and the highest professional conduct.
To place service before profit, the honor and standing of the profession before personal advantage, and the public welfare above all other considerations.
In humility and with the need for divine guidance, I make the pledge.
