With the rapid advancements in technology over the last 50 years, the Surveyor’s toolkit has greatly expanded. Traditional methods of land measurement were replaced in the 1960’s and 70’s by use of infrared technology to measure long distances accurately, and quickly this technology was incorporated into theodolites resulting in “total station” instruments. Modern technology allows these infrared beams to be bounced back of most hard objects without the use of a reflecting prism. Today GPS technology is allowing survey accurate positioning in 3 dimensions, and this technology is widely used in both the construction industry as well as for Surveying. In simple terms GPS equipment uses man made satellites orbiting the earth to calculate a position on earth. The accuracy being a function of the number of satellites available, and the quality of equipment. The innovations that are being incorporated into this equipment continue to increase the efficiencies in surveying and provide better results to our clients
