The spatial sciences profession ( surveyors, map makers and those who work with location information) placed over 60 GPS Marks at significant locations around Queensland during 2009 to commemorate Queenland's 150th anniversary and 150 years of surveying in Queensland.  The marks accurately depict latitude and longitude and provide the public with a means to check the accuracy of their in-car, in-boat and hand-held navigation devices.

The project was launched at the Museum of Lands, Mapping and Surveying in Brisbane on 24 June 2009.

Queensland's early explorers were often surveyors. Local members of SSSI (Surveying & Spatial Sciences Institute) Queensland will tell the stories of early surveyors and map makers by placing signs adjacent to many of the GPS Marks and celebrating 150 years of Queensland's history through public events celebrating the past and showcasing the future of the profession.

This area was first opened up in 1880 by surveyor Thomas H Fitzgerald for the purpose of cultivation of sugar cane, Geraldton, later to be renamed Innisfail, was established in 1881.  Surveyor W J Callendar was the first long term resident surveyor in Innisfail, operating from 1890 until 1922.  In 1891 he was "Laying out blocks from 30 to 50 acres" for Colonial Sugar Company employees to buy and grow sugar on.

Your Global Positioning System (GPS)
The GPS satellite system uses a constellation of 24+ satellites , orbiting the earth twice a day and sending down data to your GPS unit.  The data from three or more satellites is used to calculate where it is on the surface of the earth.

The satelittes send a signal that is picked up by the GPS receiver. The GPS uses that information to show you where you are.
