Integration of 3D BIM Models in a Web GIS for Life Cycle Asset Management

In recent years, there has been a growing necessity for 3D geoinformation in urban planning and infrastructure management to provide a more realistic representation of urban areas and the built environment. A key concept in public infrastructure management is Life Cycle Asset Management (LCAM), which aims to improve the decision making in each...

Exploring the Use of the Semantic Web for discovering, retrieving and processing data from Sensor Observation Services

Developments such as smart cities, the Internet of Things (IoT) and the Infrastructure for Spatial Information in Europe (INSPIRE) are causing a growing amount of observation data to be produced. The Open Geospatial Consortium (OGC) has developed Sensor Web Enablement (SWE) standards for modelling and publishing this data online. However, their...

The Visualization of Urban Heat Island Indoor Temperatures

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...

3D Intersection operations for voxel data represented as surfaces in GIS

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...

Towards a Web application for viewing Spatial Linked Open Data of Rotterdam

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...

Implementing the WPS Standard; A Case Study for Dissemination of Coastal and Marine Tools

The Open Geospatial Consortium has been developing a wide range of open standards for the field of Geographical Information (GI). One of the standards allows for remote processing; the Web Processing Service (WPS). WPS has not been implemented in many project yet but it is a promising standard which can also be applied outside the field of GI....

INSPIRE-compliant web services: The case of Narew National Park, Poland

The main objective of this research project was to assess the quality and feasibility of the guidelines for INSPIRE Network Services. The completeness, clarity, consistency and ease-of implementation of the guidelines were considered. Part of this assessment is also the question: how can INSPIRE compliance be tested and measured? The topic was...

Visualization of a TEN (Tetrahedral Irregular Network) in a web client.

This thesis is about the visualization of a Tetrahedral Irregular Network (TEN) in a web client. A tetrahedron is the simplest geometric form in 3D space, a pyramid with a triangular ground face. Its four points can lie anywhere in the 3D space as long as they do not lie on one plane. 3D objects can be composed from multiple tetrahedra. In a...

OpenGIS Web Feature Services for editing cadastral data: Analysis and practical experiences

Since Web Feature Services can be used to edit geographic data over internet, Web Feature Services should be able to process geometric transactions. Therefore for this MSc research project, the following research question has been answered: How should geometric transactions be processed in a distributed GIS using OpenGIS Web Feature Services? To...
