sense-making & knowledge discovery with location based data
DESCRIPTION
The increasing ubiquity and proliferation of location based data comes with a need to make sense of it. Geovisualisation provides a tool with which, through the exploitation of our powerful perceptual abilities, we can uncover patterns and links between previously disparate data sources. However, in the context of sense and decision making, presenting information through the frame of location is not enough – a holistic system, that incorporates geovisualisation, needs to be aware of the broader context in which it exists. A point represented by GPS coordinates can have different meanings to different people, and even an individuals’ interpretation of a location can change over time. This presentation was given at OZCHI24 in Brisbane, Australia on the 27/11/10. To find out more about my research visit www.prosimian.com.auTRANSCRIPT

2. Geo-Visualisation as a sense-making tool
3. The importance of context
1. Project overview
How can Parks Victoria better utilise the knowledge it's staff have?
Geo-knowledge project
Geo-knowledge project
Currently, valuable park specific knowledge, obtained by rangers through years of experience, is inaccessible to other rangers and vanishes completely when rangers move on.

How can we retain and disseminate this knowledge?

Knowledge is subjective
'Knowledge' implies a 'knower', and does not exist outside social contexts and human interactionKnorr Cetina (2000), Seely Brown & Duguid (2000) and Ackoff (1989)
Geovisual analysis, through the employment of highly interactive interfaces, focuses on the human elements of interface interaction and data exploration
Fabrikant & Lobben, 2009
Social objects are the core of social interactionKnorr-Cetina (2000)
Visualisations as Social Objects
Visualisations, through interaction and interface design, become social objects.
Visualisations as Social Objects
...and enable a shared understanding to be reached.
Visualisations as Social Objects
Studying interactions with space
Interpreting qualitative data to inform context
Hoping to uncover...
An understanding of "place" - as different rangers see it.
The relationship between people, knowledge and location.
