Starting with a naive question
Do Public Participatory GIS (PPGIS) have a tendency to acclimatize more easily in certain
regions of the World ?
33
Where can you find PPGIS ?
When you read the (huge) scientific bibliography about PPGIS
It seems to be more common in USA or Canada than in Europe (UK excluded)In Africa, more current in English than in French speaking countries…False impression ? Linguistic bias ?Let’s have a look to the French case

PPGIS in France
“Not any serious experience of Public Participation GIS have ever been observed in France” (Peribois 2007) Some explanations :
French model of local governanceComplexity and redundancies in the organization of local authoritiesGrowing discrepancy between real decision at intermunicipal level and election at municipal levelProblems of dissemination and public access to Geographical Information (Roche 2003)
More fundamental reasons related to French socio-territorial organization (no grassroots and local based communities as in north-american society) ?

PPGIS in France
In the 5-10 last years, things have been changingReference to participation is general in France Participatory approaches are becoming common at local scale or for national and large scale project GIS are very intensively used by municipalities and local or regional bodies.
But PPGIS is still not a real keyword in FranceNeither in urban and land planningNor in French research agenda
66
Participative mapping
Participating planning is developing quite fastFrench researchers have been involved in Participative Mapping since the beginning
In France (Gautier, 2001) (Chastel et al. 2001) (Thinon 2003) (Letissier 2004)in French-speaking African countries (Clouet 2001) (d'Aquino 2002) (Boutinot et al. 2009)In other southern countries as well (Caron 2001) (Bonin et al. 2002) (Imbernon 2002)
Italian researchers are very active in French-speaking African countries (Burini 2005) (Casti 2005) (Casti 2009) Participative Mapping is rarely connected to GIS technology

What is PPGIS ?
88
Origin of PPGIS
A specific geographical context (North America) : PPGIS was coined during 2 meetings at National Center for Geographic Information and Analysis in 1996An answer to the critiques of GIS as return to positivism, instrument of capital control, government surveillance. In response development of a new generation of GIS: GIS/2 (GIS two or GIS too)A slogan : “empower less privileged groups in the society, improve the transparency, influence government policy” A question : How GIS technology could support public participation for a variety of possible applications ? PPGIS were born in direct relation with debates within the academic scene about role of GIS in society and social science.
(Sieber 2006)

PPGIS or PGIS ?
Participatory GIS come from “counter mapping”, (mapping against status quo), community action and is promoted as an extension of GIS to development countries situation
North : Public Participation GIS PPGIS is practiced in the North as an intersection of Participatory
Planning and Geographical Information Science and Technology
South : Participatory GIS PGIS is generally practiced in the South as an intersection of
Participatory Learning and Action (PLA) methods and GIT&S.

Progressive extension
New specialists attracted : urban planners, environmental experts, social workers
new experiments and practicesMore professionalized organizations adapted PPGIS : NGO in developing countries or community organizations in charge of local developmentIn USA and industrialized countries structure of community organizations has progressivly shifted toward professionalized organizations
Expanded budgets, range of activities, numbers of paid staff (Elwood 2006)
Now PPGIS is a global umbrella embracing a multiplicity of contexts, methods, actors, situations, disciplines, milieus
1111
PPGIS : a complex amalgam
Action-oriented and pragmatic field and active academic research fieldTechnology oriented questions with a strong epistemological and critical echo
Critical cartography (Crampton 2006), social and critical GIS (Pickles 1995) (Schuurman 2000, 2002)
An interdisciplinary research grounded in value and ethical frameworks : social justice, ecological sustainability, improvement of quality of life, redistributive justice, nurturing of civil society, etc
And a set of tools of methods used by professionals of planning and development

Outside of the PPGIS field
Main research questions addressed in France
Research works in France
Geographical Information technology barely emerged as a subsidiary questionThe focus is on production and use of spatial representations :
Role and status of spatial representation in “territorial” projectHow to use spatial representation to support participative approaches in different fields of application : environment, landscape, urban planning
Two approachesPragmatic approach : experimenting different kind of methodologies for fostering participation in “controlled” and real conditions as wellTheoretical approach of the act of” spatially representing” in territorial governanceRelations between theory and experimentation
(Debarbieux et al. 2002, 2003) (Lardon et al. 2001) (Lardon 2008) (Lussault 2003)
Technology questions not addressed

Some recent examples
The workshop “Spatial Modeling and Partipatory Territorial Decision” took place in Saint-Etienne in June 2007Series of participatory workshops in the form of gamesObjectives : gathering researchers and professionals for:
Learning participatory toolsEvaluating the appropriation of the tools by the usersImproving the toolsSharing experiences and considering the diffusion of the tools and methods (Batton-Hubert et al. 2009)

Main results of the experiment
ProsAn interesting way to debate of different methodological approaches Fostering the capacity to invent, build and test new solutions Mixed audience (professionals and researchers) facilitates the transfer of tools and methods to real problems
ConsDifficulties in taking in count the planning process as a wholeNo link to a more conceptual and general approach of planningHow to connect different tools on the same problem

Review of questions addressed in PPGIS literature
Several typologies proposed (Schlossberg 2005) (Turkucu et al. 2008)A very useful or complete review of pending themes and critical questions (Sieber 2006) :
Place and PeopleTechnology and DataProcessOutcomes and Evaluation

Critical questions
Sieber’s questions :Extent of GIS TechnologyAccessibility of DataAppropriateness of InformationRepresentation of Knowledge
Representation/visualization Local Knowledge Combination of different knowledge Expert /lay knowledge
29
Place of GIS
Important : Obviously, data and technology has to be connected to context, places, people, process, outcomes… As Sieber writes :
“It is an odd concept to attribute to a piece of software the potential ton enhance or limit public participation in policy making. However, that is exactly what has happened with GIS (…)" Yes, but GIS is not really a piece of software…
30
What is and is not GIS ?
GiS is not …… a software … a mapping tool… a database
GIS is an Information SystemInformation is not easy to define (Poore et Chrisman 2006) GIS is composite. It includes people, institutions, data and data bases, computers and software, methods and protocols that have to be set up to produce one evolving outcomea sort of socio-technical arrangement including (but not limited to) fluxes and transformations of data
31
GIS vs Cartography
Historically GIS and Cartography as “Science” are very close
GIS could be quickly considered as a “dematerialization” of scientific maps
They have in common:A reference to a commensurable Euclidian spaceinteroperability” where one dataset is commensurable with anotherSpace conceptualized into points, lines, areas, and surfaces (Crampton 2006) Scientific goals, perfect formalization of a language …Preeminence of the concrete, material and visual dimension of the objects (Casti 2009) More oriented to built environment, physical processes than to describe social relations
Critical GIS and cartography
GIS and cartography have faced with the same critical approach
Political and social implications not consideredTechnocratic, abstract and Cartesian approach interested in formal processes and objects and not in their role in human experience, personal or collectiveNo place for social interpretation, cultural transmission, idiosyncrasies … Realist and positivist philosophy…
32
GIS vs mapping
Opposition between GIS as hardware and software for interactive spatial data visualization and maps, mapping and mapmaking as concrete objects is fading away
“Geodigitalisation” is a global a rapid trend Geoinformation processing combines brain, algorithms, hand, eye and mouse , paper and screen
D’Aquino (2002) notices that in a rural African contextlearning to use a Role Playing Game on a computer running a Multi Agent System is not difficult for ordinary peoplereading and making a map needs anyway some training too
What maters is not computer or not computer but that the combination of tools and practices fits the project

« Neogeography »
Beyond this inadequate word a very interesting process considering Participatory GIS or mappingNew “Web 2.0” tools (virtual globes ,mashup, api) are based on geospatial technology but did not spring from the academic or industrial fields as GIS or cartography New people involved in building tools that allow ordinary people to generate personal or collective geospatial data on the WebPeople spatially interact through social networks and provide a lot of personal and collective informationThese tools are already used in local participatory projects (in London with Google Maps API)
Ambiguities
One slogan :Cartography and GIS are no longer in the hands of experts but in the hands of the users.
Some factsUser Generated Content is supposed to highly profitableSpace, location, place are a huge market opportunityNew economic actors emerge in the industry that are global with an hegemonic project (Microsoft, Google, phone operators…)
Some questionsStatus and protection of personal dataNot actual business model for the “Web 2.0” activity

First example : Google Map Maker
Google Map Maker allows you to contribute, share and edit map informationFor certain regions around the world (Southern countries), you can locate yourself, draw, label, describe and moderate local map features.

Conclusion
GIS, spatial databases, maps, location tools and services are going to be integrated in something more general.
The process is global even if it depends on the level of computer and Internet equipment of a country
Frontiers between GIS-map producers and GIS-map users are blurring We have to understand how “ego-centered tools and methods” will be articulated to “geo-centererd tools” (Ormaux vocabulary)We cannot anymore think maps or GIS databases as disconnected“They help make connections to other representations and to other experienced places” (Hanna et al. 2004)The questions addressed by PPGIS have never been so essential
Thank you !

Various definitions of maps
A conventional representation of Earth surface“Une carte est une représentation géométrique plane, simplifiée et conventionnelle, de tout ou partie de la surface terrestre dans un rapport de similitude convenable qu'on appelle l'échelle. “F. Joly. la cartographie. PUF
A representation of spaces in a formal language“Représentation fondée sur un langage caractérisée par la construction d'une image analogique d'un espace” (Dictionnaire de la Géographie, de l’espace et des société de Lévy-Lussaut)
Maps as a facilitator in human experience,Graphic representations that facilitate a spatial understanding of things, concepts, conditions, processes, or events in the human world” (Harley and Woodward 1987) cited by (Crampton 2006)
