During this year, GEOURB Group performed geodetic measurements on a large number of buildings, business facilities and industrial plants using various geodetic measurement techniques.

People often ask questions about the benefits of 3D laser scanning of land and objects in comparison to the classic methods that were used earlier. When it is necessary to perform geodetic measurements of complex architectural objects, such as historic buildings on several floors or large industrial plants, the most commonly used advantages of 3D laser scanning.

3D laser scanning is, as previously mentioned, suitable for such complex objects with a large number of details. It comes to its full expression, providing precise and accurate data.


Direct measurement with portable devices

Geodetic measurement is done by measuring the length and width of the object in question, the distance from the edge of the room to the door, the height from the floor to the ceiling, etc. The building is geometrically divided into different rooms and rooms that are made, which are interconnected.

The connection between these rooms is done by connecting common elements, these are the most common doors or passes between different zones of the given object. In this type of measurements, the thickness of the walls of the building is also taken into account, because each measure is important for the further success of the project. This method of measurement is the cheapest, because it does not require any investment for the purchase of a laser device. On the other hand, it is the least accurate and it is only suitable when geodetic measurement of simple small and medium objects is performed.

Topographic measurement

This type of geodetic survey is suitable if it is necessary to measure a complex of real estate and complex areas of multiple levels. The research is carried out in two phases: topographic measurement and direct measurement. In the first phase, the geometry measures the location of a large number of significant points such as the building's foundation or bearing pillars and with great accuracy. These measures are used to connect different areas measured by a direct method.

3D laserr scanning

In the next step, the topographic measurement will be integrated with direct measurement. The geometry of the different areas will be measured without the need to pay attention to how they will be linked, and for their global positioning, the surveyor will use a topographic survey. This method requires initial investments for the purchase of a topographic station, the use of which enables the accuracy and precision of the measured objects to be obtained.

3D laser scanning

GEORB Group, when it comes to geodetic measurement of land and buildings, bestowed the highest confidence on 3D laser scanning. In the previous blogs, we have already mentioned that only in this way are the most accurate data when it comes to inaccessible, complex areas with a lot of details. Using this technology requires greater financial investment, but only with a 3D laser scanner we gain the advantage of precision, compared to the previous two techniques.

So let's summarize:

3D laser scanning time is 10 times faster than conventional geodetic measurement.

The accuracy of the data collected is far greater and the duration of the project is scaling down.

A smaller number of resources is used in the data collection phase, the costs of the project are lower and the productivity of the enterprise that the project leads is much higher.

3D laser scanning, in relation to 2D, has the advantage that the detected object is rendered in a more innovative and precise way.

GEOURB Group with the latest 3D laser scanner and a team of trained professionals provides services that geodetic measurement rises to a higher level, and helps you to get to high-quality projects at affordable prices and expedited procedures.
