Evaluation of the landscape
around rural roads
The environmental sustainability of the actions carried out by the
human beings into the environment is a worry for a
society aware of the wealthy heritage that they own. The study of
environmental measures and the proposal of technical solutions for
achieving the integration
of those actions show the interest to maintain and preserve this
heritage. Rural
roads are linear infrastructures that environmentally influence into an
important extension of territory, and which main characteristic is the
landscape
fragmentation derived. The
integration process of the road into the
environment has to be mainly achieved in the earliest stage of the
project. A
fair identification of
the most important attributes of the landscape and an objective
assessment of
them could provide important decision criteria for selecting the most
appropriate routes. Landscapes
of 38 rural roads in Spain
has been evaluated and
statistically analyzed in a study concerning the identification of the
significant attributes as well as the relations among them to determine
the
weight that they should receive. This aimed to establish the basis for
the
development of a specific method for landscape assessment around rural
roads.

Modelling Spatial Proximity
The
concept of proximity is an important aspect of human reasoning. Despite
the diversity of applications that require proximity measures, the most
intuitive notion is that of spatial nearness. In this talk, we will
investigate the underpinnings of the notion of nearness, explore
suitable formalisations and their implications to the processing of
geographic data. I propose that nearness should be defined from impact
areas which take both the nature of an object and the surrounding
environment into account. Context is introduced to incorporate the
wealth of knowledge that is brought into the processing of geographic
data by end users.

Visualise your message and make
it stick
Competition
between bits of information is high and from the sea of information
generated every moment only a few messages survive and become important
in our lives. Visualising your message can help making it stick. This
presentation will show some key ingredients to making your message
stand out by showing some concrete examples in the hot topic of climate
change. Come along and learn how you can apply visualisation to create
impact! |

Multisensor personal navigator
supported by machine learning
The
prototype of a personal navigator, which integrates the Global
Positioning System (GPS), micro-electro-mechanical inertial measurement
unit (MEMS IMU), digital barometer, magnetometer, and human pedometry
to support navigation and tracking of military and rescue ground
personnel has been developed at The Ohio State University Satellite
Positioning and Inertial Navigation (SPIN) Laboratory. This
presentation will provide a review of the navigation techniques
suitable for personal navigation followed by the design, implementation
and performance assessment of the system prototype, with a special
emphasis on dead-reckoning (DR) navigation supported by the human
locomotion model. A summary of the performance analysis in the mixed
indoor-outdoor environments, with the special emphasis on the DR
performance is provided. The system’s navigation limitation in DR mode
is tested in terms of time and trajectory length to determine the upper
limit of indoor operation before the need for system re-calibration.

Delineating the Littoral Zone:
Issues and Solutions
(PhD completion)
The
vast majority of boundaries within the littoral zone are based on one
of the many possible tidal lines. These tidal lines are defined by the
line of intersection between a particular tidal datum and the land
mass. This research presents the results of case studies involved in
the development of the land and water input datasets and the consequent
delineation of tidal lines. |

Integrating
vector datasets of varying quality
(PhD completion)
As the spatial information industry moves from an era of data
collection to one of data maintenance, new integration methods to
consolidate or to update datasets are required. These must reduce the
discrepancies that are becoming increasingly apparent when spatial
datasets are overlaid. It is essential that any such methods consider
the quality characteristics of, firstly, the data being integrated and,
secondly, the resultant data. This research develops techniques that
give due consideration to data quality during the integration process.
Applicable to any overlaid vector datasets, they enable preservation of
spatial integrity constraints and generate updated quality parameters. |

An agent-driven virtual
environment for the simulation of land-use decision making
(PhD completion)
This
research investigates the use of a virtual decision-making environment
as a tool for better understanding individual land-use choice
behaviour. A series of quantitative and qualitative experiments were
conducted to determine the extent to which subjects’ land-use decisions
were affected by varying the visual and social context (as represented
by a 3D visualisation and agent-based model) provided in the virtual
environment. The extent to which people's values were correlated with
their land-use choices was also investigated. |

Exposing Uncertainty:
Communicating fitness for use for spatial data over
the Internet
(PhD completion)
After decades of research into spatial data quality, there has been
very
little empirical research conducted into how consumers really determine
whether data is suitable for them. Theories were drafted in
workshops on quality in the early 1980s but since then spatial data has
moved from the specialist domain to the everyday Internet
user.
This research has investigated consumer perceptions and reasoning, and
consequently suggests some concise strategies for communicating quality
to consumers that would obtain data through the Internet.

Cadastral Data
Modeling - A Tool for E-Land Administration
(PhD completion)
Electronic administration of land is challenged by increasing needs of
clients for land information and by creation of new land related
commodities and interests. Existing administration systems, including
the latest ICT enabled systems, are not sufficiently flexible to
accommodate these new interests and commodities. Nor do they respond to
the needs of end users. This research will develop a new cadastral data
model that incorporates a broader range of interests and commodities
and satisfies the emerging demands of users. |

Improved
Processing Models for Network Kinematic GPS Positioning in Sparse
Networks
(PhD completion)
Network Kinematic GPS can realise centimetre level positioning
accuracies using regional networks of reference stations (CORS), with
typical separations of up to 70km. This spacing is not practically
feasible across large regions such as Australia. To overcome this
limitation and expand the utility of GPS, this research developed
algorithms to accurately determine GPS biases at CORS sites using
undifferenced processing techniques. Results indicate that accurate
position solutions can be computed at rover sites that are over 100km
from CORS sites. |
