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.

Sense-Making & Knowledge Discovery with Location Based Data Sense-Making & Knowledge Discovery with Location Based Data Presentation Transcript

  • GeovisualisationSense-making and knowledge discovery with location based dataChris Marmo, Bill Cartwright & Jeremy Yuille OZCHI 2010
  • Today...1. Project overview2. Geo-Visualisation as a sense-making tool3. The importance of context
  • Geo-knowledge project View slide
  • Geo-knowledge project How can Parks Victoria better utilise the knowledge its staff have? View slide
  • 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.
  • 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?
  • Geo-knowledge project
  • Geo-knowledge project Knowledge
  • Geo-knowledge project Knowledge People
  • Geo-knowledge project Knowledge People
  • Data Information
  • Knowledge is subjective Knowledge implies a knower, and does not exist outside social contexts and human interaction Knorr Cetina (2000), Seely Brown & Duguid (2000) and Ackoff (1989)
  • (Geo)Visualisation
  • Geovisualisations = geovisual analytics
  • Geovisual analysis, through the employment of highlyinteractive interfaces, focuses on the human elements ofinterface interaction and data explorationFabrikant & Lobben, 2009
  • The importance of context
  • Visualisations as Social Objects Social objects are the core of social interaction Knorr-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.
  • Locations have different meanings for different people
  • Rangers
  • Space vs PlaceHarrison & Dourish (1996)
  • Space is the raw location, minus context
  • Place arises through interactions with space
  • Can we use "place" as context to knowledge?
  • Studying interactions with space
  • Studying interactions with space Interpreting qualitative data to inform context
  • Hoping to uncover... The relationship between people, knowledge and location. An understanding of "place" - as different rangers see it.
  • Greater sense-making Rich Understanding Knowledge of Place Interactive Interfaces
  • Acknowledgements...Bill Cartwright, Jeremy Yuille, Monique ElsleyARC Linkage grant
