Surveying & Land Measurement

Precise measurement of terrain data, conversion into digital maps and creation of a reliable base for engineering projects.

Surveying is the first step of every engineering project. Before a building, road or facility can be designed, the existing state of the site has to be measured, brought into a digital environment and turned into a reliable base that project teams can work on. If that base is wrong, every calculation after it carries the error.

GNSS/RTK receivers and total stations are used together. Satellite-based measurement is fast in open terrain, but where satellite visibility is limited — dense development, tree cover, deep excavation — the total station takes over. Which method is used where is decided by site conditions.

Maps are delivered in CAD format and can be used directly in zoning, construction, infrastructure or expropriation processes. Survey points are tied to the national coordinate system, so measurements taken at different times by different teams still line up.

  • Digital Base Maps

    Precise measurement of natural and man-made features on site, modelling them in a digital environment and preparing maps that serve as a base for a wide range of engineering projects.

    Scope

    • Digital base map
    • Topographic map
    • Spot level plan (plankote)
    • Detail surveys
    • Triangulation, traverse and levelling works
    • RTK/GNSS and Total Station measurements

  • Topographic & Corridor Maps

    Collection and mapping of topographic data along the route for roads, power lines, infrastructure and other linear engineering projects.

    Scope

    • Corridor (strip) maps
    • Route surveys
    • Longitudinal and cross sections
    • Base data for road and junction projects
    • Infrastructure and superstructure surveys

  • Land Setting-Out & Boundary Demarcation

    Applying parcel and project data to the field; precisely establishing boundaries, corner points and project points on the ground.

    Scope

    • Land setting-out
    • Building setting-out
    • Boundary demarcation
    • Parcel corner points
    • Transferring project coordinates to the field

How We Work

Process

  1. Site inspection

    The site is visited and the conditions that affect method selection — vegetation, development, access, satellite visibility — are assessed on the ground.

  2. Control network

    Permanent triangulation and traverse points are established on site and tied to the national coordinate system. Every later measurement rests on this network.

  3. Detail survey

    Natural and man-made features are measured with GNSS/RTK and total station; height data is supported by levelling.

  4. Office processing

    Raw observations are adjusted, error checks are run and the data is turned into a digital map.

  5. Delivery and review

    Outputs are delivered in CAD format; where required, the file structure is prepared for authority review.

FAQ

Common questions

What is the difference between a base map and a topographic map?
A topographic map shows the terrain with height information. A digital base map adds man-made detail — buildings, roads, infrastructure, parcel boundaries — and is used as the official base in zoning processes.
How long does a survey take?
It depends on site size, terrain relief and the level of detail required. A small, flat plot is usually surveyed in a day; large and uneven terrain increases crew size and days. A firm duration is given after the site has been seen.
Do I need to be on site during the survey?
No. Parcel information and access permission are enough. Where boundaries are disputed, however, having the owner or neighbours present makes the process easier.
In which format is the map delivered?
Standard delivery is DWG and DXF. Additional formats such as NetCAD, PDF or coordinate lists (TXT/CSV) are prepared on request.
