Application Of GPS-RTK Technology In Geophysical Prospecting Surveying In The City Zone

Geophysical prospecting surveying is a kind of surveying served for geophysical prospecting constructing. Its purpose is staking out pre-designed points on the spot, drawing the sketch map, supplying surveying results. This paper has briefly described the action of surveying in geophysical prospecting constructing and the development of geophysical prospecting surveying technique, analyzed application actuality and foreground about RTK technique, discussed the significance of RTK developing in the city zone, included principle and method of RTK surveying. In practical application, the method and progress of RTK technique application in geophysical prospecting surveying by the line deploying and observation system of geophysical prospecting has been studied. Measures have also been studied to ensure the precision of geophysical points surveying. In the city zone, with top buildings standing, various difficulties occur in constructing, a series of method has mentioned in top building surveying and geophysical points staking out. The effect has been offered in one practical example In north-east of Sichuan Province.
