Next Generation – supporting TU Dublin final year students

It was with great pleasure that we loaned a Trimble X7 3D Laser Scanner to the BSc Geospatial Surveying TU Dublin final year students.

KOREC is always delighted to support the next generation of surveyors coming through college, and especially when they’re keen to get their hands on some ground breaking Trimble technology! It was therefore with great pleasure that we loaned a Trimble X7 3D Laser Scanner to the BSc Geospatial Surveying TU Dublin final year students for a project that was also supported by a number of survey service providers.

The Project

Christ Church Cathedral has stood at the heart of Dublinfor almost 1000 years and this important heritage site welcomes visitors from all over the world every day. Facilitated by the Cathedral’s staff,  the final year students were lucky enough to work as a team on an assignment that required them to undertake a series of scans to provide the cathedral with floor plans of the inside and elevations of the exterior. The end results were to be handed to the Cathedral’s insurance company before a policy renewal.

The Deliverables

On Site

The students were divided into two separate teams, a laser scanning team and a control network team.

A control  network to geo-reference the scans was established. The exterior of the building, minus the roof, was then scanned in just a day using the Trimble X7 and involved around 54 setups.

The students found the instrument ,and the tablet connected to it, very intuitive and following the initial setup, very simple to use: “All we had to do is press “start scan”. The X7 did the rest of the work!”

Highest rated Trimble X7 feature

The students rated the automatic registration and the self-levelling features above all. Automatic registration meant that they did not have to register the scans when they got back to the office whilst the attendant report allowed them to prove the accuracy of their work to the client and lecturers.

The self-levelling feature was also appreciated for the way it cut down on site time – the whole building scanned in a single day.

Finally, being able to geo-reference the project on site meant less work when it came to post-processing. The students were also able to colourise their scans on export.

After the survey

The final year students presented their survey and scan results in the beautiful Henry Roe room in the Cathedral.

Our thanks to Dylan de Beer and Adam Hoey for their feedback on both the project and of course the X7. Both felt the use of a top range 3D Laser Scanner to be extremely beneficial their studies and also a good indicator of what industry standard surveying can be like with the use of good equipment.
