Welcome to Spatial@Melbourne

The University of Melbourne is home to an enormous collective expertise in spatial information, ranging from sensing through data management, analysis, decision making and visualisation and application. Collectively, Spatial@Melbourne belongs to the leading concentrations in the world. The Spatial@Melbourne initiative brings the groups and individuals at the University of Melbourne active in spatial research, teaching and engagement together in this virtual home.


FOSS4G SotM Oceania – Student registrations

There is a limited number of student registrations for FOSS4G OCeania, which will go first to students who are presenting at the conference (presentations or workshops). As a reminder, presentation submissions are due on 31 August, so get your abstracts ready!

Any remaining student registrations will be released in mid-October and will be first come, first served. See the Registration page for more details on the different registrations available”

Day registration for GIScience 2018

Some special day tickets are available for GIScience 2018 for $100 ($50 for the Friday half-day). These tickets are only open to researchers at the University of Melbourne and RMIT University, and only available until 19th August. They don’t include any social events/goodie bags etc., only the technical program. So, in case you don’t fancy registering for the whole conference, but still fancy seeing some of the technical program (see: http://giscience.org/full-conference-program/) there is an option to register for just one day of your choice here.

Open Data Survey

The University of Melbourne has partnered with the Department of Premier and Cabinet (DPC) in Victoria, Australia to develop a survey on open data. The survey, Open Data in Practice: Attitudes of Government Agency Workers, is now open to participants. It aims to capture the attitudes of open data workers and other stakeholders towards open data and evaluate the current state of open data policies across Australia.

To complete the survey, visit https://www.surveymonkey.com/r/5C5MW6G

Using Geographic Information in a HASS Virtual Lab: Geocoding Requirements

Researchers in the humanities are increasingly adopting new technologies and engaging with a variety of digital resources and services. With the increasing availability of both historic and real-time data, there is an increasing opportunity for researchers to harness the power of geographic information (GI) to support exploration, analysis and presentation tasks. The goal of this 2 hour interactive workshop is to principally understand how HASS researchers using GI can be supported with geocoding tools.

Audience: Researchers with direct experience using geographic information and geocoding tools are encouraged to attend.

When: Thursday, 3rd May, 10:00 am- 12:00 pm.

Where: The Lab, Level 2 of the Digital Studio, West Wing of Arts West (access via the rear lift).

Public Seminar by Prof Hanan Samet, University of Maryland

Who: Prof Hanan Samet, Department of Computer Science, University of Maryland.
When: Thursday 22nd March, 11:00 am – 12:00 pm.
Where: PAR-Old Geology-G04 (Theatre 1), The University of Melbourne
Moving object databases arise in numerous applications such as traffic monitoring, crowd tracking, and games.  They all require keeping track of objects that move and thus the database of objects must be constantly updated.  The cover fieldtree (more commonly known as the loose quadtree and the loose octree, depending on the dimension of the underlying space) is designed to overcome the drawback of spatial data structures that associate objects with their minimum enclosing quadtree (octree) cells which is that the size of these cells depends more on the position of the objects and less on their size.  In fact, the size of these cells may be as large as the entire space from which the objects are drawn.  The loose quadtree (octree) overcomes this drawback by expanding the size of the space that is spanned by each quadtree (octree) cell c of width w by a cell expansion factor p (p>0) so that the expanded cell is of width (1+p)*w and an object is associated with its minimum enclosing expanded quadtree (octree)
cell. It is shown that for an object o with minimum bounding hypercube box b of radius r (i.e., half the length of a side of the hypercube), the maximum possible width w of the minimum enclosing expanded
quadtree cell c is just a function of r and p, and is independent of the position of o.  Normalizing w via division by 2r enables calculating the range of possible expanded quadtree cell sizes as a function of p.  For p>= 0.5 the range consists of just two values and usually just one value for p>=1.  This makes updating very simple and fast as for p >= 0.5, there are at most two possible new cells associated with the moved object and thus the update can be done in O(1) time.  Experiments with random data showed that the update time to support motion in such an environment is minimized when p is infinitesimally less than 1, with as much as a one order of magnitude increase in the number of updates that can be handled vis-a-vis the p=0 case in a given unit of time.  Similar results for updates were obtained for an N-body simulation where improved query performance and scalability were also observed.  Finally, in order amplify the result, a video titled “Crates and Barrels” is available which is an N-body simulation of 14,000 objects.  The video as well as a JAVA applet that illustrates the behavior of the loose quadtree are both available from here.
