What is a topographic land survey?

Topographic land surveys involve the production of maps and plans which are true to scale. The maps are created to display and accurately represent details of both the natural and built environments within the area in question. Land Surveys are undertaken by our experienced and dedicated land surveyors who utilize an array of equipment including GPS/GNSS, Total Stations, Precise Digital Levels etc.

What information should be presented on a topo-map?

A detailed topographic survey has many uses across the natural and built environments. Typically, they are conducted on a set parcel of land to depict natural/man made features and elevation changes giving you a clear picture prior to any planned works. Detail is accurately measured and the deliverables issued to meet our client’s specific requirements. These can range from simple 2D contour plans to detailed AutoCAD drawings.

At Guideline Surveys, we utilize Autodesk CIVIL 3D to generate comprehensive topographical maps, crucial for our clients' subsequent planning and design endeavors.
r detailed topographic mapping encompasses:

  • Identification of existing trees and vegetation.

  • Positioning of current permanent structures such as buildings, utility poles, and communication towers.

  • Mapping of existing boreholes, wells, utility chambers, drainage systems, and manholes, including their respective invert levels.

  • Representation of contours with 0.5-meter intervals and block levels tailored to meet client specifications.

  • Additional detailing within a 100-meter radius from the client's property boundary.

  • Determination and depiction of the width and location of existing watercourses (Nala)

GNSS Surveys were previously called GPS Surveys. GNSS stands for Global Navigation Satellite System. GNSS Surveys use the existing satellite systems of GPS (American system), GLONASS (Russian system) which give optimum satellite coverage for a full 24 hours of survey allowing us to undertake surveys all year round in all weather conditions.

When used by our skilled surveyors, GNSS provides surveying and mapping data to the highest level of accuracy. Using the latest Trimble GNSS survey equipment and with the help of Survey of India’s CORS Network allows faster data collection than conventional surveying techniques, reducing the amount of equipment and labour required. A single surveyor can now accomplish in one day what once took a team of surveyor’s weeks to do.

Unlike traditional techniques, GNSS surveying technology is not bound by constraints such as line of site visibility between the prism and total station making it particularly useful when surveying coasts, waterways and rivers banks, brown & greenfield sites.

boundary survey


The purpose of a boundary is to provide a safe, simple and economic system of land transfer. So, if you’re a business or homeowner, knowing where to draw the line can be extremely important. At GUIDELINE SURVEYS we offer expertise and experience in providing surveying services in relation to boundary disputes in both domestic and commercial environments. With expertise in mapping and measurement, a land surveyor’s work in a dispute involves accurate measurements of the area in question.

Following the local government regulations and code of Ethics, our calm and independent approach can provide both sides in a dispute with confidence in the reliability of the information that we provide, in circumstances in which there may be a breakdown in trust and communication between disputing parties.

setting out and Marking


This is the process of transferring architectural proposals from drawings onto the land itself. It establishes controlling dimensions and references from the architect’s plans on the land, that will determine the positioning of the building, and in particular its foundations. These include; overall length and width, distances to road center-lines and to other structures, internal structural measurements, approaches and rights-of-way and so on. Additionally, it establishes the building's correct extent, angle and level.

The controlling points of the structure can then be clearly shown with physical markers so that the construction team is able to easily identify them. This usually consists of marking the building’s corners plus horizontal and vertical positions by using stakes, batter boards with string lines, drill holes, cut-and-fill notations, and other methods. Based on physical markers set out by a surveyor, the construction team will start their building work.


These surveys are important because:

  • They allow for construction to be done within the legal boundary, thus eliminating the chance of boundary disputes later on

  • They enable the construction team to build exactly to the architect’s / engineer’s plans

road survey


Highway surveys are used to provide highly accurate and detailed plans of existing road networks. Features such as the location of kerbs, services, street furniture, utilities, drainage, neighbouring buildings, overhead cables, camber of the road, street furniture and many more to assist in the use of infrastructure projects & transport planning.

Highway surveys are essential for the use of transport planners, architects and engineers to understand and design new access entrances and visibility splays for new projects and developments. Visibility Splays are an essential feature of an access or junction, as it allows traffic at the new junction to see cyclists, vehicles and pedestrians on the main road. An unobstructed visibility splay or sight line allows a motorist to see and be seen and with appropriate visibility splays or sight lines road users have time to see and react to any potential incident.

as built survey


As-built surveys are needed to record variations from the original architectural master and engineering plans to what has actually been built. As Built Surveys are required by many agencies such as the local authorities, in order for them to adopt the proven location of buildings, road networks and services for the maintenance and future development of site.

As-built surveys actually include the internal and external survey of standing buildings or structures. It can include a variety of outputs ranging from a basic floor plan to a detailed 3D building model.

  • Walls

  • Ceiling Plans

  • Floor Plans

  • Space

  • Access

  • Elevations

  • Sections

  • built information

  • As built surveys

  • Complete cross and longitudinal sections showing building as

  • Internal partitions, stud wall, solid walls

  • Doors, risers, access hatches, fire escapes, windows, stairs, lifts

  • Full external elevations showing building profile, window heights, roof heights etc.
