Basically, land surveying is the science of measurement of spatial positions of the features on the surface of the Earth. The purpose of conducting a land survey is to locate the positions of selected points on or near the surface of the Earth. It can be further elaborated that Land Surveying is the process of determining the boundaries, area or elevations of land or structures on the Earth's surface via taking angle and distance measurements. (Dictionary.com, 2006)

Each of the various kinds of surveys described below is some form of variation of the above description. We pride ourselves on providing a complete solution to your surveying needs. For each of these surveys, the finalised survey will come in the form of survey plan(s), endorsed by our Registered Surveyor.

Cadastral Survey
Such a survey is done either to determine the lengths and directions of boundary lines and the area bounded by these lines, or to establish the positions of these boundaries. This is termed as Cadastral Survey (aka Title Survey).

Engineering Survey (Topographical survey, As-built surveys)
The purpose of such a survey is to determine the configuration of the ground (Topographical Survey), a survey made to locate or lay out engineering works are known as Engineering Surveys (Construction Surveys).

Gas-pipe and Power cable surveys
This survey is done to lay out the position and the length of the gas-pipe(s) or power cables and after the pipe or cable is laid, the survey is carried out to determine its final laid position and length.

Tunnelling Survey
This is a survey conducted to locate and/or lay out a tunnel's position. This is a rather specialised field with the survey calculations aiding to guide a Tunnel Boring Machine in the correct direction and position.

Deformation Monitoring Survey
This survey is carried out to determine the effects, if any, on an influenced zone (usually an area in or surrounding construction works). It is a repetitive survey conducted at regular intervals such that the data collected over time can then be analysed for a trend to determine any effects. This kind of survey is further categorised into 2D or 3D monitoring.

A 2D example being Ground Settlement Monitoring while 3D monitoring is typically employed for structures. Finally, because of its repetitive nature, in certain areas (such as tunnels) it is performed automatically vis--vis installing an automated monitoring system.

Other surveys: GIS information
GIS, short for Geographical Information Systems, is a spatial information database built from geographical and geographically referenced data. It links information to location based data, and different layers can be chosen for analysis for a specific purpose. In short, it's a system that aids in decision-making via various analyses that can be performed on the data collated and managed on the system.
