Surveying and Mapping

This section offers services that combine professional staff, state of the art equipment and software to ensure that we offer the full suite of Topographical surveying, Engineering surveying, Hydrographic surveying, Cadastral surveying, Control surveying and Training in Land survey related short courses such as GNSS Training, Total station training, leveling among others.

Surveying or land surveying is the technique, profession, and science of determining the terrestrial or three-dimensional position of points and the distances and angles between them. These points are usually on the surface of the Earth, and they are often used to establish maps and boundaries for ownership, locations like building corners or the surface location of subsurface features, or other purposes required by government or civil law, such as property sales. Surveyors use equipment like total stations, robotic total stations, GPS receivers, retroreflectors, 3D scanners, radios, handheld tablets, digital levels, subsurface locators, drones, GIS and other surveying software.

The main disciplines of surveying are:

• Land surveying.
• Engineering surveying.
• Mining surveying.
• Hydrographic surveying.
• Geodetic surveying.
• Photogrammetry and remote sensing.

Land surveying: Land surveying involves measuring and determining property boundaries, which are used as the basis for all property transactions including buying, selling, mortgaging and leasing. Due to the importance of having a secure and strong property market, in Kenya a land surveyor needs to be licensed to be able to carry out a land survey.

Engineering surveying: Engineering surveyors are engaged in the construction industry and ensure construction works are built in the correct location and as per their design. They are generally found on construction sites setting out various types of works such as buildings, roads, bridges, tunnels and various other forms of infrastructure.
Mining surveying: Mining surveyors are involved in the development and construction of mining operations and can generally be found above and underground taking measurements to determine volumes and setting out new excavations and tunneling.

Hydrographic surveying: Hydrographic surveying involves locating and measuring points under the sea and on the shore. There measurements are used to design infrastructure such as docks and jetties as well as ensuring ships have enough clearance from the sea bed to safely travel around the world. Using sonar scanners they are able to provide a picture of the sea bed without needing to get their feet wet and enabling the discovery of ship wrecks and other objects lost at sea.

Geodetic surveying: Geodetic surveyors are involved with undertaking very precise measurements to determine the shape and size of the world and track the movement of continents. Their measurements are used in the monitoring of sea level rise, earthquakes, and the tracking of satellites. Geodetic surveyors are involved in the development of co-ordinate systems and datums which are used in the productions of maps and plans.

Photogrammetry and remote sensing: Photogrammetry and remote sensing involves taking measurements of the world via photography or other wavelength bands such as infra-red or ultra-violet. Measurements may be sources from aerial photography or satellite imagery. Photogrammetry and remote sensing is used to map large areas and determine changes in the world over time.
