The effect of 3D geometry complexity on simulating radiative, conductive and convective fluxes in an urban canyon

The Geomatics Synthesis Project (GSP) was an eight-week culminating group project by seven second-year MSc. Geomatics students. The objective was to undertake group and fieldwork through a real-world project with an external organization. In association with Laboratoire des Sciences de L'Image Informatique et Teledetection (LSIIT) at the...

Using Existing Wi-Fi networks to Provide Information on Occupancy and Exploitation of Educational Facilities using at Delft University of Technology

This executive summary provides an overview of the work done by project in_sight for the TU Delft MSc Geomatics for the Built Environment. The research subject is the usage of WiFi monitoring data to calculate the occupation of the TU Delft campus in order to determine the exploitation of the educational facilities.

Determine activity based on the classified identity of users by using Wi-Fi monitoring

The Wi-Fi technologies are used in everyday life on numerous applications that detect the crowd information for commercial, security and other reasons. The Wi-Fi monitoring can be used for tracking people when they are moving along different access points. The results from the Wi-Fi monitoring can provide the location of the users in an area and...

Identifying movement patterns from large scale Wifi-based location data: A case study of the TU Delft Campus

Location is a key element of many processes and activities, and the understanding of human movement behaviour is becoming increasingly important. Knowledge of people’s locations and related mobility patterns are important for numerous activities, such as urban planning, transport planning and facility management. How to efficiently use the...

Automatic thematic and semantic classification of 3D city models

Developments in remote sensing created new possibilities to capture the human environment on a large scale. This data is used in the generation of large scale Three dimensional (3D) city models, which has led to a higher demand for 3D city models in a wide range of fields. The lack of semantic information in many 3D city models is a considerable...

Using a Space Filling Curve for the Management of Dynamic Point Cloud Data in a Relational DBMS

The rapid developments in the field of point cloud acquisition technologies have allowed point clouds to become an important source of information for many applications. One of the newest applications of point clouds concerns the monitoring of the coast. Many countries, among which the Netherlands, use this source of data in order to determine...

Exploring the use of a generic spatial access method for caching and efficient retrieval of vario-scale data in a client-server architecture

Vario-scale data structures make it possible to derive maps at arbitrary scale. When requesting a map, data has to be transferred from server to client. This takes time, which affects the responsiveness of the system, and sometimes costs can be involved for every byte that is send over the network. Redundant data transfers should thus be avoided...

Smart Asset Management in the construction sector: A holistic research into utilising the potential of sensor technology

Double Degree Program - The introduction of integrated contracts in the construction sector results in shifting risks and responsibilities from the client to the contractor. In contrast to traditional forms of contracting, contractors become often also responsible for an operational period. The obligation to ensure availability and reliability...

Designing an integrated future data model for survey data and cadastral mapping

For nearly 200 years the Netherlands’ Cadastre, Land Registry and Mapping Agency – in short ‘Kadaster’ has been the organization that registers and maintains all legal rights concerning property in the Netherlands. An elementary part of its activities is the spatial description of parcels that are built up by boundaries which are surveyed in the...

The identification of road modality and occupancy patterns by Wi-Fi monitoring sensors as a way to support the “Smart Cities” concept: Application at the city centre of Dordrecht

As world urbanization continues apace and total population increases, there is an immediate demand for better monitoring and exploitation of space. In view of the above, the “Smart Cities” concept has been developed and numerous efforts are made to deploy technology to this end. The main information needed for city development and planning is...
