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 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...

The urban heat island (UHI) describes the phenomena that the city heats up faster and stays warmer than its rural surroundings. The combination of ageing societies and increasing temperature, due to climate change, poses serious challenges for the health and wellbeing of the increasing urban population. Assessments of the urban heat island...

Indoor positioning is becoming a hot topic in public areas that are used by large numbers of people. Finding people and assets in buildings has become more difficult because of the complexity and scale of today’s public space. On the subject of locating assets in the hospital the following use case is defined for this project. Positioning and...

Fugro GeoServices is currently storing their CAD models of the Petrochemical Industry as attributes of 2D lines in a spatial DBMS. This solution works well for web visualization, but not for performing analyses in 3D. The main objective of this graduation project is to create a 3D spatial DBMS with solid CAD geometries as input. The difficulty...

This thesis focusses on the intersection 3D Boolean set operation on voxel data represented as surfaces, with other 3D surface based vector data, in GIS. The Application of this research makes the linkage with geohydrology possible: based on the vectorised GeoTOP (TNO) data the water infiltration and storage capacity of specific locations can be...

All existing data sources used to reconstruct 3D building models have certain restrictions. An eye-catching alternative is IndoorOSM, one of the most popular examples of the newly evolved crowdsourced geodata. The potential power of this rich and simple-formatted data source has been proven by many researches. However, a fatal flaw of IndoorOSM...

Nowadays, not all pedestrian paths are accessible for mobility impaired people. Especially paths which consist of complex public spaces and old streets constitute problems. However, no reliable information is (quickly) available about problems that cause hindrance. The sensing rollator called meet rollator is equipped with several sensors that...

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...

Point clouds can be obtained by airborne or terrestrial Light Detection and Ranging (LiDAR) scanning or directly from street-view panoramic imagery. Point clouds obtained from airborne scanners cover most roof information but lack facade information. Similar but orthogonal to airborne scanning, street-view point clouds cover well of the facade...

Facade reconstruction from terrestrial LiDAR point cloud is affected by both quality of point cloud itself and imperfectness of object recognition algorithms. In the facade, there are many features, which are shared within an object or among objects. For example, within one window, the boundaries of it may share parallel and orthogonal...

Freight is moved by trucks on the road more and more, which is a worrying thing, especially for the environment. A very good alternative to transportation by trucks is transportation by trains. The Dutch government aims to increase the transportation of goods by train from 13% of all transportation to 20% of all transportation, but in reality,...

With the help of technologies such as GPS tracks, GIS and open data is now possible to study people travel behaviour in a new way. Nowadays, large datasets can be easily handled thanks to database and better visualized using GIS. Moreover, the availability of GPS data, open data and VGI makes accessible a lot of new information, which was not...

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...

Governments and municipalities open up their data and publish spatial data on the Web, to be transparent to their citizens and to stimulate innovation. This spatial open data can be confusing for non-GIS experts, since data is published as either typical geo-formats or metadata is missing. Linked data could benefit in that regard. Linked data is...

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...

Persistent Scatterers Interferometry (PSI) is a well-known space geodetic technique for measuring surface deformation. Deformation estimates obtain under blind conditions (i.e. processed without the usage of a-priori information) can be questionable and controversial. The problem manifests itself when different users process the same radar data...

Finding one's way in complex indoor settings can be a quite stressful and time-consuming task, especially for users unfamiliar with the environment. There have been several different approaches to provide wayfinding assistance in order to guide a person from a starting point to a destination, ranging from traditional maps and signposting systems...

This research proposes an algorithm for the generation of realistic plant distribution for both existing and future areas using spatial data. The main motivation for this research is to be able to generate realistic plant positions for the 3D visualization of existing and future natural environments. Current techniques for determining plant...
