PPGIS: From desktop to the GeoWeb

741 views

Published on

Abstract:
Public Participation GIS (PPGIS) defines 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). PPGIS is viewed as a top-down process where a central authority identifies a problem, the stakeholders and the best way to address it (Ghose, 2007). Current advances in the GeoWeb are challenging the top-down purview of PPGIS in that more citizens are directly engaging with tools that enable the collection and communication of place-based knowledge by non-experts. This emerging process raises pertinent questions, including: How is knowledge of place expressed, and to what extent is it relevant to PPGIS? This talk will highlight local research that centered on Edmonton’s river valley trail network where 17 informants were interviewed regarding their knowledge of place, in addition to their collection and communication of place-based information. This research will address the crowdsourcing of such information through the GeoWeb as a means of replacing traditional, authority controlled, PPGIS processes. We will demonstrate that individuals possess a complex, detailed and nuanced understanding of place. And, finally, we will discuss the current limits and future trends of the GeoWeb’s ability to capture that depth of understanding.

PPGIS: From desktop to the GeoWeb

  1. 1. Public Participation GIS: From the Desktop to the GeoWeb. Matthew Dance
  2. 2. 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?
  3. 3. 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.

  5. 5. 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
  6. 6. Diagram of a Collaborative Spatial Methodology From Balram and Dragicevic (2006)
  7. 7. 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).
  8. 8. 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.
  9. 9. 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
  10. 10. Results: Mental Maps
  11. 11. 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. Chris Results: Nuanced Understanding

  14. 14. 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.
