3D model of the Notre Dame Cathedral. (Image: Andrew Tallon/Vassar College)
Notre Dame Cathedral in Paris has reopened its doors five years after the devastating fire, showcasing its restored interior after extensive rebuilding work. The restoration, costing approximately €700 million ($737 million), was financed entirely by donations from around the world.
On April 15, 2019, Notre Dame went up in flames, with the spire collapsing and the roof being destroyed. The following years were dedicated to rebuilding the cathedral, including the reconstruction of the spire and the restoration of stained glass and woodwork.
A crucial element in the restoration process was the point cloud data collected by professor Andrew Tallon, an architectural historian from Vassar College, in 2010. Tallon’s project, which aimed to fully understand the Gothic structure and identify structural anomalies, involved creating a precise 3D model of Notre Dame using a Leica Geosystems terrestrial laser scanner.
This cloud of 1 billion points proved indispensable for the digital recreation of the cathedral’s interior and exterior. Tallon’s laser scans were the only truly accurate as-built measurements of Notre Dame, translating point clouds into detailed representations of its buttresses, ribbed vaults, stained glass, ornate carvings and other architectural details.
The value of point cloud data
While modern restoration efforts cannot fully replicate the artistry of centuries past, Tallon’s scans have been instrumental in reconstructing the Gothic cathedral, allowing architects to come remarkably close. Although Tallon died in 2018, his groundbreaking work remained a vital resource for restoring the iconic cathedral.

Tallon’s meticulous 3D scans of Notre Dame provided architects with information crucial for the cathedral’s reconstruction, including:
Precise 3D models: Tallon’s precise 3D model of Notre Dame included intricate details of the cathedral’s architecture, such as flying buttresses, rib vaults, stained glass windows and ornate carvings. This level of detail was unmatched by any historical drawings or records, which often lacked precision.
Dimensional and formal reconstruction: Pascal Prunet, one of the architects tasked with rebuilding the cathedral, said in an interview with Lindsay S. Cook that the point cloud data provided an “exact trace” of the cathedral’s state at the time of scanning, allowing him and his team to reconstruct elements — such as the vaults — “without hesitation” regarding dimensions or forms. This was essential for accurately rebuilding complex structures such as flying buttresses and rib vaults.
Structural analysis: The scans revealed structural details that were previously unknown, aiding in understanding how the cathedral was originally constructed and how it changed over time. This information was vital for designing custom supports and ensuring structural stability during reconstruction.
Integration with modern technology: The point cloud data was integrated into Building Information Modeling (BIM) processes, which allowed architects to create a digital twin of Notre Dame.
Restoration guidance: The scans provided a highly detailed record of Notre Dame’s pre-fire condition, which helped restoration professionals select appropriate techniques for stabilizing and rebuilding various parts of the cathedral.
Why precision matters
The two architects highlighted the crucial role Tallon’s laser scan of the cathedral played in their restoration process. They shared how this detailed digital model provided them with precise measurements and structural information, enabling Notre Dame to, in essence, “guide its own restoration.” By relying on this accurate data, the team could ensure its work remained faithful to the iconic cathedral’s original design and construction.
Tallon’s laser scan of Notre Dame Cathedral has proven invaluable in the restoration process. This digital twin, created in 2015, offers an unparalleled level of precision and detail, capturing the cathedral’s every nuance with accuracy up to 5 mm. This level of detail allows the restoration team to address the structure’s complexities and make informed decisions about the rebuilding process, ultimately helping to preserve Notre Dame’s authenticity and historical integrity.

For decades, surveying — which consists largely of making measurements to determine the relative positions of points above, on or beneath Earth’s surface — had much higher accuracy than mapping for geographic information systems (GIS) — which is mostly based on aerial photogrammetry for base maps and field data collection of the locations of features. When I started in this field a quarter century ago, we typically classified GPS receivers as survey grade, resource grade or consumer grade, with “resource grade” referring to field data collection for GIS.
Today, however, the accuracy of all receivers has greatly increased — thanks to improved chipsets, new GNSS constellations, and a plethora of corrections services — and those three categories are no longer relevant. Therefore, surveying and mapping are increasingly overlapping.
For this cover story, I asked the same three questions about mapping and surveying to representatives of four companies.

Surveying and mapping are increasingly overlapping. What are the remaining differences between them, in terms of accuracy requirements and challenges in the field?
CHC Navigation
While advances in technology such as lidar and photogrammetry are narrowing the gap, there are still notable differences between surveying and mapping. Surveying often requires centimeter- or even millimeter-level accuracy at specific points. In contrast, mapping focuses on collecting dense 3D data over large areas. Although the accuracy of mapping point clouds is steadily increasing, the integration of ground-based GNSS data collection with aerial imagery and lidar is becoming widespread. Mapping tends to be less labor-intensive and involves fewer safety risks in the field, but it requires a unique skill set, particularly in point cloud processing.
Hexagon
Traditionally, surveying and mapping differ primarily in their accuracy requirements and application scales; however, this paradigm is changing with mapping becoming increasingly accurate. Surveying focuses on high-precision geospatial data of specific points. From road, rail and tunnel construction to high-rise buildings, there is no substitution for the precision delivered by surveying equipment and procedures. In contrast, mapping focuses on larger areas.
Recent advancements in sensor technology, including both airborne and mobile mapping systems such as the Leica CityMapper-2 and the Leica Pegasus TRK, have significantly improved the efficiency and precision of mapping, bringing it closer to the levels achievable with traditional surveying equipment.

Surveying comes with a large overhead during the data collection process. It requires meticulous preparation and attention to detail to achieve high accuracy in the raw data. GNSS quality, lever arms, user operation, etc., can all cause problems later on. Getting any part of the process wrong can have major cost implications through having to redo the process.
Mapping is focused on the act of aligning that data to datums and control points after the surveying process is completed but it also requires major attention to detail in aligning coordinate frames and origin points in order to avoid baking in any errors that lead to mistakes being made once the map data is handed over to a customer
The problem is that if the surveying process wasn’t accurate, the mapping process will not have a solid foundation in the raw data to deliver accurate maps, so they are inherently tied to each other.
Trimble
Surveyors today have many tools in their toolbox, giving them flexibility across surveying and mapping applications. There are many highly accurate, easy-to-operate data capture systems to choose from these days, but challenges grow when combining and analyzing vast amounts of data from different sensors in the office to provide final deliverables. This has made field-to-finish software that delivers technological integration, workflow optimization and adaptability essential for the job.
Mapping projects often require less accuracy, but a lot of advanced survey technology is entering the mapping domain (e.g., mobile mapping and laser scanning) because of easier field operations and increasing understanding of the value of rich data to asset management.
The data were collected in and around a car park to prove how Lidar Inertial Odometry (LIO) can be used to retain accuracy for longer periods without GNSS updates. (Photo: OxTS)
