Automatic segmentation and classification of movement trajectories for transportation modes

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...

Quality assessment and object matching of OpenStreetMap in combination with the Dutch topographic map TOP10NL

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...

Automatically deriving and updating attribute road data from movement trajectories

There are many applications that use maps, and more detailed the maps are, more applications can benefit from the map. Many maps are still manually created and also the underlying attributes are informed in a manual process. This thesis presents a method to automatically derive and update attribute road data by mining and analyzing movement...

Analysis of mobility patterns in different neighbourhoods, integrating GPS tracks with OpenStreetMap data

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...

Analysis of Urban Space Networks for Recreational Purposes based on Mobile Sports Tracking Application Data

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...

Community mapped elevation through a low-cost, dual-frequency GNSS receiver: A performance study in Delft (the Netherlands) and Dar es Salaam (Tanzania)

Heavy rainfall, combined with expanding (unplanned) urban settlements in flood prone areas, expose Dar es Salaam (Tanzania) to the risks of flooding. The urbanisation is so rapid in many areas that it is not beneficial to carry out expensive surveys which are quickly out of date. The work carried out by community-mapping project Dar Ramani Huria...

The Potential of Using OpenStreetMap Data in Population Synthesis: A Case Study in Zoetermeer

Recent years have seen a rise in computation power, storage and opensource data has become more accessible. This results in new opportunities for microsimulation models. Most of these models require a realistic population but the data for this is usually not available. Therefore, population synthesis is used to generate the statistical...

Assessing an open spatial data infrastructure from a user participation perspective: A qualitative exploratory research of OpenStreetMap

Geographic Information (GI) has proven its value with its ability to be used in various fields, which left numerous questions about how this data should be stored, used, and managed. To facilitate the sharing and reuse of spatial data, Spatial Data Infrastructures (SDIs) emerged in the last decades and with the increase in Open Data, the belief...
