Land Surverying


Land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.

Topographical Surverying


A Topographic Survey is a survey that gathers data about the elevation of points on a piece of land and presents them as contour lines on a plot.

Road Surverying


Road surveying is the technique, profession, and science of determining the terrestrial or three-dimensional positions of points and the distances and angles between them.

Water Line Surverying

Water Line

Water Line Surveying is use toidentify shallow underground features, for example underground pipes/membranes as well as lying surface water.

Construction Site Surverying

Construction Site

Construction Staking, also known as a Site Layout Survey, is the process of interpreting construction plans and marking the location of proposed new structures such as roads or buildings.

Drone Surverying


There are several reasons why land surveyors are increasingly adding drones to their portfolio of instruments. Droe surveying makes X, Y and Z mapping easy.

GPS Surverying


Surveying and mapping was one of the first commercial adaptations of GPS, as it provides a latitude and longitude position directly without the need to measure angles and distances between points.

Cadastral Surverying


Cadastral surveying is the sub-field of surveying that specialises in the establishment and re-establishment of real property boundaries. It is an important component of the legal creation of properties.

Building Settingouts


Construction surveying or building surveying (otherwise known as "staking", "stake-out", "lay-out" or "setting-out") is to stake out reference points and markers that will guide the construction of new structures such as roads or buildings.

Contour Settingouts


A contour or a contour line may be defined as the line of intersection of a level surface with the surface of ground. This means every point on a contour line has the same altitude as that of the assumed intersecting surface.
