The Urban Heat Island (UHI) is a phenomenon in which a city forms microclimates which heat up significantly quicker than its rural surroundings. Urban environment has a tremendous and not extensively explored impact on human health and on environment. Until now the UHI was mostly studied by the means of satellite remote sensing techniques. This...

The Netherlands is characterised by mostly low lying, flat, and engineered agricultural lands, which are sensitive to flooding. To protect against floods, a correct network characterisation is of the utmost importance. A Dutch water resources management company, the HDSR, wishes to have a highly automated method to characterise the water course...

The recent emergence of Light Detection And Ranging (LiDAR) scanning technology has resulted in the availability of very large three dimensional point cloud data sets. These LiDAR data sets have become a main source for the modeling and reconstruction of both ground surface as well as above-ground objects such as buildings and vegetation. For...

Even though studies of the built environment’s impact on citizens’ physical activity have become an aspiring topic in the recent years, up to now the most investigated topic is transport-related walking or cycling. However, little is known about the patterns of leisure-related physically active travels. One of the reasons behind this lack of...

Solutions have been introduced to handle massive point clouds in Database Management Systems (DBMS), namely by Oracle in 2011 and postgreSQL in 2013. Many common operations on these massive point clouds require knowledge about the original surface in order to analyse them. A possible method to recreate a representation of the original surface is...

In recent years, the concept of 3D city models has been gaining in importance as more 3D geometry of urban areas is becoming available. Although 3D City models offer a structured way of storing geometry, in practice a significant amount of geometry is not considered valid. This hinders the further analyzing or processing of these models. Since...

CityGML is a standardized data format used to store the semantic information and geometries of buildings and other object classes of 3D city models. The Level of Detail of current state of the art city models (LoD2) is not sufficient for accurate environmental simulations like noise, the solar potential of windows and other types of analyses. An...

Depth-contours are an essential part of any hydrographic chart—a map of a waterbody intended for safe ship navigation. Traditionally these were manually drawn by skilled hydrographers from a limited set of surveyed depth measurements. Nowadays this process of map making is shifted towards the digital domain, not in the last place because of the...

Three-dimensional maps are deemed better for navigation purposes as they offer a larger number and more realistic navigation cues than two-dimensional maps. Improvements in two key technologies have opened the doors towards utilization of 3D maps for car navigation devices. Advances in data acquisition technologies and data processing methods...

The possibility of an automatic object matching process in combination with a VGI (Volunteered Geographical Information) type of map has been explored in this research. TOP10NL, the topographic map of the Netherlands and OpenStreetMap (OSM), the VGI type of map have been chosen for this purpose. The object matching process in this research...

For the creation of three-dimensional (3D) city models, extrusion of building footprints is widely applied. Extrusion results in block shaped buildings. The main problem with these 3D models is that they do not represent height differences within a building. This thesis presents a method to improve building footprints by subdivision into parts...

Planar partitions (subdivisions of the plane into polygonal areas) constitute one of the most important data representations in GIS. They are used to model concepts as varied as land use, administrative units, natural features and cadastral parcels, among many others. However, since polygons are often stored separately, different errors and...

The knowledge of the transportation mode used in a movement trajectory (derived in form of timestamped positions) is critical for applications such as travel behaviour studies. This thesis presents a method for segmenting movement data into single-mode segments and their classification with respect to the used transportation mode. The method...

In this thesis the use of the discrete 3D Voronoi diagram in modelling continuous fields in geosciences will be assessed. The Voronoi diagram is a structure that divides a certain space into cells, called Voronoi cells. These cells are created so that every location within each cell is closest to the corresponding data point, or seed, of that...
