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 Queensland's 150th anniversary and 150 years of surveying. 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.

Q150 ( 1859 - 2009) GPS Mark

Celebrating 150 years of surveying and providing a spatial future on Queensland.

In 1865, First class surveyor Clarendon Stuart was instructed to carry out the first official survey of the new town on Cleveland Bay originally settled by J M Black - Townsville.  Despite the loss of most of his left hand in an earlier shooting accident, Stuart surveyed Black's preliminary subdivision scheme and extended a proper survey over what later became the centre of the city. This sundial was originally located in Flinders Mall.

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.
