Land surveyor
Land surveys, boundary demarcation and setting out by a sworn expert land surveyor
Building a home, selling a plot or want to know exactly where your boundary lies? Then you need a land surveyor. A land surveyor accurately maps your land or building and delivers the plans your architect, notary or contractor can work with.
TOPO4D is a sworn expert land surveyor for classic land surveying: topographic surveys, boundary demarcation, setting out, survey plans and pre-cadastral registration. We measure with total stations and RTK-GNSS and deliver legally and technically sound plans you can build on.
What does a land surveyor do?
A land surveyor measures land, plots and buildings and turns those measurements into plans and digital files. Think of a site plan with levels for your architect, an as-is plan for a regularisation, or the exact position of your property boundaries.
Some assignments may only be carried out by an expert land surveyor. For instance, marking out land and signing plans for a boundary agreement or a transfer of ownership is legally reserved for surveyors registered as expert land surveyors on the roll of the Order of Expert Land Surveyors. TOPO4D is a sworn expert land surveyor, so you can come to us for both.
Our surveys can be used in planning files, notarial deeds, architectural plans and permit applications. For buildings and complex structures we complement the survey with 3D laser scanning, and for movements over time with monitoring.
How does a land surveyor measure accurately?
At TOPO4D, accuracy is the standard. The measuring method we choose depends on the site and on the plan you need:
- Total station: measures angles and distances to a prism and is the standard for buildings, foundations and detailed surveys.
- RTK-GNSS: determines coordinates directly on site using satellites and a correction signal, ideal for open land and larger plots.
- Traversing: for larger or complex surveys we set up a network of survey points and adjust the closing error, so all measurements are consistent with one another.
- Drone LiDAR and aerial imagery: for large or overgrown sites we add a drone survey. A LiDAR sensor under the drone also maps the ground surface beneath vegetation.
All points receive coordinates in Lambert 72 and heights in TAW. This way your plan ties in with cadastral data, municipal plans and your architect’s design.
You receive a site plan, boundary plan or demarcation report in the format you need, such as PDF, DXF or DWG.
Which land surveying services does TOPO4D provide?
From a simple site survey to a full boundary determination: as a land surveying firm we combine classic surveying with modern measuring technology. These are the assignments you most often call on us for.
Topographic survey
We survey levels, plot boundaries, buildings, paved areas and trees and process everything into a site plan. That plan is the basis for your architect’s design or a building permit application.
Boundary demarcation
Unsure where your boundary lies? During a boundary demarcation we determine the boundary based on deeds, cadastral plans and measurements and mark it with boundary markers. Everything is recorded in an official report.
Setting out
When setting out a new build, we mark the axes and corner points of your home on site according to the site layout plan. That way your contractor starts in the right place and at the right height.
Survey plans and pre-cadastral registration
Selling part of a plot? Then we register the survey plan in advance with the Patrimonial Documentation administration through pre-cadastral registration. The new plot thus receives its own identification for the notarial deed.
As-is survey
For a renovation, regularisation or change of use, we survey existing buildings and their surroundings. You receive plans, elevations or sections as a starting point for your design.

Frequently asked questions about land surveyors
How much does a land surveyor cost?
What a land surveyor costs depends on the size and location of the site, the type of survey and the output you need. A boundary demarcation with research, for example, takes more time than a simple level survey. For an exact price, request a free, no-obligation quote.
What is the difference between a land surveyor and an expert land surveyor?
A land surveyor measures land and buildings. An expert land surveyor also holds a protected title: they have taken the oath before the court of first instance and are registered on the roll of the Order of Expert Land Surveyors. Only an expert land surveyor may mark out land and sign plans for a boundary agreement or a transfer of ownership.
When do I need a land surveyor?
Among other things, for a building permit application, the sale or division of a plot, doubts about your property boundary and the start of a new build. For a renovation or regularisation, a survey of the existing situation is also a good basis.
What is a topographic survey?
A topographic survey maps the relief and all visible elements on a site: levels, boundaries, buildings, roads, trees and utilities. The result is a site plan with coordinates and levels, ready for design or a permit.
How accurately does a land surveyor measure?
With a total station and RTK-GNSS we measure to the centimetre. The achievable accuracy depends on the measuring method, the conditions and the purpose of the survey. That’s why we tailor the method to your project in advance.
What is pre-cadastral registration?
If you sell part of a plot, the expert land surveyor submits a survey plan to the General Administration of Patrimonial Documentation of the FPS Finance before the notarial deed is signed. The new plot thus receives its own identification, which the notary includes in the deed. This procedure was introduced by the Royal Decree of 18 November 2013.
