Public Participation GIS:
From the Desktop to the GeoWeb.
Matthew Dance
Purpose
To connect the rich human geography tradition
of place-based enquiry to the emerging
GeoWeb.
1. How is knowledge of place expressed?
2. How is this relevant to PPGIS?
Talk Overview
1. Context: Overview 15 years of PPGIS.
2. My MA research: Place based communication
via emerging tech.
3. Bringing these two related themes together.
4. Current and future trends in location based
collaboration.
Do you recall…?
Kevin Lynch, The Image of the City, 1960
PPGIS the early years…
A practice where GIS technology and methods
are used in support of public participation and
decision making in a number of domain
applications (Sieber, 2000).
• Top down & authority driven
• NOT collaborative
• Concerned with problems defined by
authorities
• Stakeholders are to be mined for data
Diagram of a Collaborative Spatial
Methodology
From Balram and Dragicevic (2006)
Mapping, Mashups, and Beyond
Early 2000’s – Basic web maps such as
MapQuest.
2005 – Launch of Google Earth (now at over 1
billion downloads).
2005 + - Ubiquitous Computing (Ubicomp) via
hand held smart phones and the Internet of
Things where inanimate objects talk to each
other (i.e. Air Quality Sensors).
PPGIS: From desktop to the GeoWeb
What is ‘place’?
Place is defined as being comprised of three
dimensions (after Relph, 1976):
1. Observable activities that occur in relation to
the location;
2. The meanings that are created by a person in
that location, and;
3. The physical features that comprise the
location’s concrete or tangible attributes.
Methods
• Qualitative Methodology
• Case Study Method
– Semi-structured interviews (N=17)
• Mental Maps
• Place and space
• The GeoWeb
– Discourse analysis of transcripts
– Primary on-line sources such as Facebook &
Garmin Connect
Results: Mental Maps
There was a path in the woods there, and we call that
Moonies run because our teacher, Mr. Moonie, lived right
there. My friend played guitar and I played guitar, and we
used to take our amps, carry our amps across back and forth
across the river. At this point here right in the middle of the
bridge was we deemed that as perfectly half way, so we
would say, ‘Okay, I’ll meet you on the bridge’. But yeah, I
spent a lot of time down there, in Gold Bar.

Results Summary
Q1: How is knowledge of place expressed?
1. People have a detailed and nuanced
understanding of place.
2. Current tech does not capture this variation
and nuance.
3. Current tech is good at point-line-polygon-
real-time types of quantitative data.
So what?
Q2: How is this relevant to PPGIS?
PPGIS is dead…long live PPGIS

“The point is Waze didn’t just create a static
navigable map, it created a real-time
(crowdsourced) representation of the current
state of roads.”
Via gigaom.com
Google recently bought WAZE for 1 billion USD.

New PPGIS paradigm
Upside
• Bottom up
• User driven
• Define issues
– Who is needed to address
– Best way to address
• Realtime data
• Push notifacations
• Open data / software
• Crowdsourced data and
information
Downside
• Digital divide
• Knowledge of code a +
• Literate
• Access to computers
• Understanding of data
• Still lacking access to
nuanced understanding of
place…..
Situating citizens:
Who is a ‘place’ expert?
"Given a large enough beta-tester and co-
developer base, almost every problem will
be characterized quickly and the fix will be
obvious to someone."
Eric Raymond, The Cathedral and the Bazaar, 1999

Editor's Notes

  1. Matthew DanceRecent MA grad in Geography from the UofA
  2. Lynch was perhaps one of the first to use crowdsourced data in his research. He compiled mental maps of Boston, New York and Jersy City that were derived from interviews with people who lived within those cities. This could represent the first PPGIS
  3. Themes such as:IsolationGetting away from it allConnecting with peopleDeeply personal and varied.
  4. Thematic clusters around:Sports and recreation activitiesActivity routesImpressions of placeMemories of placeSpecial placesNotions of power relative to place
