The structural reliability of the wooden tower of the Grote of St. BavoChurch in Haarlem has been assessed with the regular methods. In addition to the regular methods, some modern technologies have been used in the structural analysis. The mechanical properties of the timber have been determined with longitudinal vibration tests and visual...

In the times of growing attention towards renovation for energy efficiency in the built environment, the building stock particularly associated with heritage value deemed monumental or protected is currently exempted under the Dutch law to comply with the energy performance guidelines. <br/>Limitations with regards to protecting the aesthetics...

Trees are of great significance throughout the world, both in urban scenes and in natural environments. Models of trees can be widely applied in various fields, for instance, landscape design, geo-simulation, environment modelling, and forestry inventories. Recently, laser scanning technology has been rapidly developed, making it possible to...

Because of urbanisation, more than 50% of the global population now lives in cities, a number that is ever-increasing. This leads to a need for more dense and complex building constructions, driven by the fact that people are living increasingly close to one another. These structures are often so large that it becomes difficult to navigate in...

Indoor environments tend to be more complex and more populated when buildings are accessible to the public. The need for knowing where people are, how they can get somewhere or how to reach them in these buildings is thus equally increasing. In this research point clouds are used, obtained by dynamic laser scanning of a building, since we cannot...

Increasing traffic weights and aggressive environmental conditions may result in unexpected deterioration of a bridge’s components. Particularly, most bridges in Europe and US over half life span are affected by such impact. Structural deficiencies may cause partial or full collapse of bridges resulting in problems for human life, economy,...

The purpose of this research is to explore the role of LIDAR Technology and Digital Fabrication techniques in the field of architectural conservation, particularly for the patching of ornamental heritage. The information is compiled in the form of a guide. Information gathered via the aid of experiments and subsequent observations is also...

Laser scanning has become a well established surveying solution for obtaining 3D geo-spatial information on objects and environment. Nowadays scanners acquire up to millions of points per second which makes point cloud huge. Laser scanning is widely applied from airborne, carborne and stable platforms, resulting in point clouds obtained at...

There is still a long way to go in understanding the behaviour of solids in sewers due to the difficulties in obtaining sufficient monitoring data to be able to understand the dominant processes. Laser profilers have shown to be capable of measuring the pipe interior, with a high accuracy, which is sufficient to be able to detect and quantify...

Change detection is an important application of laser scanning data. It is also a challenging application as errors that are inevitably present when determining the geometric state of a scene of interest in a certain epoch will somehow add up when comparing the geometric state between epochs. As a consequence it is often difficult to distinguish...

For the construction of breakwaters large amounts of armourstone which are produced in dedicated quarries are needed. The better the in-situ block size distribution (IBSD) of these quarries can be determined, the more accurately the quarry production can be predicted. Currently, the IBSD prediction is based on manually acquired scanline data....

One of the main applications of the terrestrial laser scanner is the visualization, modeling and monitoring of man-made structures like buildings. Especially surveying applications require on one hand a quickly obtainable, high resolution point cloud but also need observations with a known and well described quality. To obtain a 3D point cloud,...

The Dutch coast is characterized by sandy beaches flanked by dunes. Understanding the morphology of the coast is essential for defense against flooding of the hinterland. Because most dramatic changes of the beach and the first dune row happen during storms, it is important to assess the state of the coast immediately after a storm. This is...

The goal of this project was to see if information on the grain size distribution of a patch of cobbles could be obtained from the digital terrain model constructed from a laser scan of the cobble surface. The grain size distribution was to be extracted from the laser scans by the use of semivariograms. This was inspired by the research done by...

Pavescan is a low cost mobile system for road modelling survey. Because of the absence of navigation sensors it has several practical drawbacks compared to most of the other mobile mapping systems, but those sensors are very expensive and do not fulfil most of the accuracy requirements. Pavescan will be more attractive if some of the practical...

The use of cobbles as a dynamic revetment is a recent development in coastal protection. Cobbles are placed along the beach and they form a dynamic equilibrium with the waves, thus dissipating the energies from the wave and protecting the soft, native material from eroding. In order to optimize the design and increase the durability of this...

The Dutch coast is characterized by sandy beaches flanked by dunes. Its morphology is essential for the defense against flooding of the hinterland. Therefore it is monitored on a yearly basis by Airborne Laser Scanning (ALS). However, it is recognized that most erosion of the beach and first dune row takes place during storms. To assess the...

The application of terrestrial laser scanning to the study of rock surface roughness faces a major challenge: the inherent range imprecision makes the extraction of roughness parameters difficult. In practice, when roughness is in millimeter scale it is often lost in the range measurement noise. The parameters extracted from the data, therefore,...
