2. Geo-Visualisation as a sense-making tool

3. The importance of context

1. Project overview

Geo-knowledge project

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)

(Geo)Visualisation

Geovisualisations = geovisual analytics

Geovisual analysis, through the employment of highly interactive interfaces, focuses on the human elements of interface interaction and data exploration

Fabrikant & Lobben, 2009

The importance of context

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.

Locations have different meanings for different people

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?

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.
