St. Elisabeth Hospital | Providing healthcare to a Caribbean Island
Constructed in 1855, with the help of the Franciscan sisters, the St. Elisabeth hospital has played an important role in the Otrobanda City district on the Caribbean island of Curaçao, for over 160 years. The large hospital served as the main hub for medical care, and was historically used as a place of healing for other island nations nearby.
Having been deemed no longer fit for purpose according to international standards in 2011, it was decided that a new hospital would be constructed next to St Elisabeth’s, and in 2019 the Curaçao medical center was opened to the public. St. Elisabeth hospital was closed in November 2019, after 164 years of service to the island.
In 2021, Ellen de Brabander, from Urban Studio, was appointed by the survey bureau ‘Landmark’ with the task of scanning the hospital, in anticipation of renovation projects. Ellen chose the ZEB Horizon for the task, and later created an accurate BIM model using the point cloud data. In addition, Ellen is working on creating a virtual tour of the hospital, so it can be entered and explored from anywhere in the world.
Scanning with the ZEB Horizon
Due to the large complex nature of the building, with several floors and many individual rooms, the task of capturing and measuring the hospital was an enormous one, in terms of time frame. Originally Ellen was going to scan the building using a total station, however because the hospital is broken into 6 sub-buildings, an average of 3 floors per sub-building and many individual rooms per floor, the total station was quickly ruled out. Furthermore, with difficult to access areas, the bulky nature of a tripod-based system would not be ideal for capturing the hospital in its entirety, or fast enough.
After assessing the options, the team decided the best way to capture the building would be to use a mobile 3D scanner, due to the lightweight nature, speed of capture and ease of use. Ellen chose a ZEB Horizon for the job and was able to seamlessly walk through the hospital’s complex buildings, capturing data as she moved.
The 3D scanner of GeoSLAM was able to reduce the time of the measurement and as a result the delivery time was met. The measurement time would normally take several months, which was reduced to days
Having decided on the ZEB Horizon, she was able to capture both the interior and exterior of St Elisabeth’s hospital in just 6 full working days, which was an extremely short amount of time compared to traditional measuring equipment. 52 scans were conducted in total, at approximately 20 minutes per scan and the area covered (including exterior and interior) was 22,346 square meters. The complex nature of some of the spaces were captured effortlessly because of the manoeuvrability and compactness of the scanner.
Post scan
The scans were processed and merged using GeoSLAM Hub before they were converted in Autodesk Recap and taken into Autodesk Revit to be modelled. The model of the hospital was sent to the client and the process from capture to model was documented in a video, which can be seen here:

Cistercian Landscapes
Professor Hess and Carla Ferreyra | University of Bamberg
Background With the adoption of digital technologies such as laser scanning, photogrammetry and other digital tools becoming ever more prevalent in conservation and preservation; it is easy to see why, in 2017, the University of Bamberg launched a new master’s degree, ‘Digital Technologies in Heritage Conservation’. Spearheaded by Professor Mona Hess, the course covers the integration and adoption of digital technologies in heritage conservation and its further development, as well as raising the profile of this research topic. In addition to running the course, Professor Hess and her team often employ their skills and expertise in the field, creating 3D digital models for preservation purposes, to build knowledge of certain areas or to educate a wider audience about a new culture.
“The 3D recording is a methodological tool for the representation and interpretation of cultural heritage, landscape and architecture, to build knowledge, create meaning and make culture accessible to all.“
The Scan In 2020, Professor Hess was approached by ‘Cisterscapes | Cistercian Landcapes in Central Europe’ and was tasked with contributing to the digital recordings of 2 gardens. The scan would focus on the baroque agricultural buildings with designed gardens; Ebracher Hof in Mainstockheim and Ebracher Hof in Oberschwappach, both properties of the Ebrach Monastery.
The aim of the scan was to create reliable information, assess the landscapes development status and design management plans for maintenance and conservation. Professor Hess, accompanied by PHD student Carla Ferreyra, visited the sites in October 2020 to conduct the scans. With approximately 3 hectares of land to cover, the team needed a SLAM scanning solution that was quick, easy to use, suitable for both indoor/outdoor use and a solution with reliable results. Professor Hess chose GeoSLAMs ZEB Horizon with the ZEB Pano, because of the rapid data acquisition throughout the site up to 100m.
Other laser scanning techniques were considered in the planning process, however none quite provided the freedom the ZEB Horizon did, often with restrictions around mobility and time. In September 2020, a similar scan had taken place using a terrestrial laser scanner (TLS) of a specific area of the Mainstockheim garden. In comparison, the GeoSLAM scanner reduced the time and labour costs when completing the scan. The team were able to complete their scan of Mainstockheim (including an interior space of the baroque building) in just under 3 hours.
In Oberschwappach, the total scan time was approximately 30 minutes. Their only concern during the scan was encountering the general public, however due to the lightweight nature of the ZEB Horizon and Pano, it was easy to avoid busier parts of the garden. Where they did encounter other guests (due to their curiosity over the scanner) Professor Hess and Carla simply repeated the scan of that specific area. All in all, the scan was a success, and Professor Hess and Carla were able to deliver on their task.
The Results With the completion of the scan, not only does Professor Hess have fresh scan data that can be used to educate the next generation on how digital technologies can be used in heritage conservation, but they are also being used to extract 2D information, such as orthophotos, plans and sections in 1:50 scale and BIM models. Furthermore, videos of the scan were created – these serve as informational and educational pieces of content. Finally, the scans serve to raise awareness of these historic gardens, promote a scientifically accurate recording and also makes the heritage accessible to all. Professor Hess is currently using the scanner and scans for research & teaching, and she has observed that a lot of her students are enthusiastic about the speed of the process.
Looking Forward In 2021 Professor Hess is looking to extend the project further at Ebrach Abbey and the gardens, to contribute to the Cistercian Cultural Heritage project. Additionally, she is looking to create a digital twin model of a historic city using the ZEB Horizon, to research semantic 3D city models with information about urban heritage in the project ‘BIM to Twin’.

Coupling with hardware
Some SLAM software algorithms have been made available as open-source on the internet, but they are purely algorithms and not a product that you can take and use off-the-shelf. SLAM is most successful when it is tightly coupled and designed with specific hardware in mind. A generic SLAM cannot perform as well as one that has been specifically designed for a purpose.
Usage in multi-environments
Visual SLAM is closer to the way humans navigate the world, which is why it’s popular with robotic navigation. But in the same vein, vSLAM will have the same image-capture challenges as humans do, for example not being able to look into direct sunlight, or not having enough contrast between the objects picked up in the image. These can be overcome indoors, however, you may need to map a forest, tunnel or urban canyon. While SLAM technologies don’t rely on remote data (meaning you can scan areas where there is no GPS), you do need to ensure the SLAM technology you chose operate well inside, outside, in daylight and darkness.
Real-time data capture
Mapping a property is time-critical. Ideally, you want to make a single visit and gather sufficient data to create a highly accurate 3D model. Ensure the software you choose transforms 3D point cloud data into actionable information in real-time. This allows you to view and interrogate your data whilst still in the field, and make any adjustments, or collect missed data, then and there.
Flexibility and deployment
If you’re trying to map an enclosed environment (e.g. tunnel, mine) or a complex, difficult-to-access space such as a heritage building with tight stairwells and uneven floors, you need to use fully-mobile, adaptable technology. Wheel-based systems, often used with the vSLAM camera, will struggle with access. Handheld devices or LiDAR scanners that can be attached to a drone or pole and still deliver accurate results in a rugged environment are best for navigating hazardous spaces.
Speed and accuracy
While vSLAM is able to provide a qualitative high-level map and sense of the surrounding features, if you’re needing survey-quality accuracy and rich-feature tracking at a local level, you’ll need to consider LiDAR. Cameras require a high-frame-rate and high processing to reconcile data sources and a potential error in visual SLAM is reprojection error, which is the difference between the perceived location of each setpoint
and the actual setpoint.
Quality and distortion
In order to deliver the depth required for high-quality data, a number of depth-sensing cameras are needed with a strong field of view. In most cases, this isn’t possible, especially as cameras with high processing capabilities typically require larger batteries which weigh down airborne scanners, or limit the time of flight. LiDAR is both faster and more accurate than vSLAM, and can deliver detailed point clouds without expensive (and timely) camera processing.
