There is a great deal of overlap with the different types of surveying, however in general terms they can be describes as follows.
Surveyors involved in land development are usually registered surveyors as legislated by the Surveying Act 2002. The Board of Surveying and Spatial Information is responsible for the registration process. Registered surveyors are often referred to as cadastral surveyors because of their involvement in maintaining the cadastre by the locating and marking of property boundaries. Registration requires a demonstration of competence in engineering, planning and all laws relating to the subdivision of land.

This type of surveying relates to mapping rivers, oceans and waterways in general. Hydrography plays an important role in preparation of navigational information for shipping as well as exploration of marine resources.

Engineering surveyors are involved in the setting out of construction projects that can be of enormous scale such as high rise buildings, roads, bridges, transmission lines etc. They can also be involved in the subsequent monitoring of the completed structure to ensure safety is maintained.

The making of Maps (Cartography) has become as high-tech as any other industry with images taken by aircraft and satellites. The Cartographer then uses these images combined with other information about the area to construct the maps.

Surveyors are involved in research projects such as global warming, monitoring of existing environments such as whale movements in the waters off the north coast of New South Wales and providing environmental impact statements for new developments.

GPS SATELLITE SURVEYING & SATELLITE IMAGERY
Surveyors use Global Positioning Systems (GPS) in all kinds of surveying. Satellite imagery is also being used to monitor movements on the earth’s surface – earth quake zones, potential mud slides or even troops on the move in a war zone.

GEOGRAPHIC INFORMATION SYSTEMS
Geographic Information Systems are simply layers of spatially interrelated maps. The layers may include information about roads, underground services, types of trees, location of retail outlets or population distribution for example. A GIS specialist links the layers so that they can be used to analyse, plan and make changes that meet the needs of the community or the environment.

Mining surveyors use the same skills as those involved in land or engineering surveys but are required to undertake additional training to manage underground work. Mining surveyors, like land surveyors are required to be registered by BOSSI.
