Contributions to Big Geospatial Data Rendering and Visualisations
… system capable of advanced rendering and data visualisations are achievable. We have investigated the combination of big geospatial data, and computer game engines for the creation of a modern geographical information system framework capable of visualising densely populated real-world …

Geospatial data obfuscation methods applied to agricultural data
… Digital farming generates a high volume of data including spatial data. This data can be used in data-driven modelling to improve agriculture systems and design and develop more sustainable agricultural policies and services to enhance sustainable agriculture. Sharing and making data …

Development of MIT geospatial data to CityGML workflows
… this thesis explores the process of translating geospatial data received from MIT into the CityGML data format, which will then be used to generate virtual environments for BlindAid. We discuss the main challenge of preserving both geometry and semantic information with respect to different data …

Beyond visualization : designing interfaces to contextualize geospatial data
The growing sensor data collections about our environment have the potential to drastically change our perception of the fragile world we live in. To make sense of such data, we commonly use visualization techniques, enabling public discourse and analysis. This thesis describes the design and …

Making Sense Out of Uncertainty in Geospatial Data
Uncertainty in geospatial data fusion is a major concern for scientists because society is increasing its use of geospatial technology and generalization is inherent to geographic representations. Limited research exists on the quality of results that come from the fusion of geographic data, yet …

Developing a collaboration network framework to facilitate geospatial data access and exchange in the context of National Geospatial Data Infrastructure (NGDI)
National Geospatial Data Infrastructures (NGDIs) provide holistic frameworks with several technological components that address and overcome geospatial access and exchange issues. The components of any NGDI area include geospatial data, people, access networks, policies, and standards that aim to …

A Framework to Annotate the Uncertainty for Geospatial Data
… to annotate the uncertainty information of geospatial data. This framework is composed of a geospatial platform and the data with uncertainty. The framework supports geospatial sources such as Geography Markup Language (GML) with uncertainty information. The purpose of this framework is to …

Geospatial Data Modeling to Support Energy Pipeline Integrity Management
… need to measure and indicate useful, actionable data for each region of interest, and operators often use computer-based decision support systems (DSS) to analyze and allocate resources for active and potential hazards.</p> <p>We designed and implemented a geospatial data service, REST API for …

Leveraging Geospatial Data to Understand Social Mixing in Cities
… In the following projects, I leverage large, geospatial datasets which capture human mobility to describe policy and design impacts on social mixing in three different urban contexts. Study 1 presents a new way to measure social segregation in mobility patterns using sparse, anonymized …

On the spatial modelling of mixed and constrained geospatial data
… and spatial relationships, categorical data such as rock types, soil types, alteration units, and continental crustal blocks should be modelled jointly with other continuous attributes (e.g. porosity, permeability, seismic velocity, mineral and geochemical compositions or pollutant …

GIS-based accessibility modelling as a means of evaluating geospatial data usability
… lack of previous research into the usability of geospatial data. Whereas considerable study has been made into the usability of devices and their interface, the underlying data has been subject to less consideration, though a substantial literature exists regarding data quality. With the rapid …

Beyond the Bezel: Utilizing Multiple Monitor High-Resolution Displays for Viewing Geospatial Data
… for storing, creating, and manipulating spatial data, yet viewing area is still generally constrained to a single monitor. With this viewing window limitation, panning and zooming are required to view the full details of a map or image and, because of the large sizes of typical database, usually …

Using Census, Institutional and Geospatial Data to Estimate the Socio-Economic Profile of Post-School Students by Institutional Type
… Part of the reason for this is because potential data sets that could be used to answer this fall short on dimensions needed to fully explore the extent of socio-economic differences amongst student bodies by institutional type. I, therefore, generate a data set that draws on institutional, …
