wikisig and collaborative geodesign
DESCRIPTION
GeoDesign is an emerging concept that aims to address key issues that impact the planning and management of human settlement and activities. Carl Steinitz from the Harvard Graduate School of Design considers that « GeoDesign is geography by design ». GeoDesign is not really a new concept, but it was updated in December 2008 at a specialist meeting on «Spatial Concepts in GIS and Design » organized by the US National Center for Geographic Information and Analysis. Following this meeting, two GeoDesign Summits took place in Redlands (CA), in January 2010 and 2011. GeoDesign was defined by Mike Flaxman (from MIT) as « a set of techniques and enabling technologies for planning built and natural environments in an integrated process, including project conceptualization, analysis, design specification, stakeholder participation and collaboration, design creation, simulation, and evaluation (among other stages). GeoDesign is a design and planning method which tightly couples the creation of design proposals with impact simulations informed by geographic contexts » . According to Goodchild (2010), GeoDesign can be considered as the combination between GIS and Design on the geographic domain and geographic scale. The creative, deliberative, uncertain, multi-actors, multi-scale and multi-thematic process of GeoDesignneeds an innovative theoretical basis, tools, supports and practices in order to fit its complex requirements.GeoDesign allows groups from different professions, places, time, to work together on a same project, and to produce plans and designs. They interact and collaborate to improve the end results by exchanging feedbacks and correct each others. GeoDesignas Design in general is based on process that is complicated by disagreements among participants, difficulties in deciding what is optimal, feedback loops that modify objectives, constraints, while the project is processing. To better understand better this concept, the work of Constance Bodurow and her lab is presented on the following section. A multidisciplinary team of architects, urban designers, civil and environmental engineers,...work together to visualize three-dimensional urban density using the GeoDesign approach and tools in Detroit, Michigan. Their interface combines the capabilities of Esri ArcGIS, Google Earth, SketchUp and other software to model physical and social density and value in three dimensions. They succeeded to suggest two new building topologies with mixed use and apartment residential, called “our max zoning proposal”.By such technology with some enhancement, they are able to empower sustainable design of other urbanized regions across the globe. Some existing geomatic technologies provide potential but incomplete answers and solutionsto thosespecific needs of GeoDesign: Sketch tools, simulation tools, threedimensional design tools, spatio-temporal GIS... But theywere not really designed forGeoDesign (...)TRANSCRIPT

GeoDesignAn emerging term: new definition but an old conceptAppeared after the specialist meeting on « Spatial Concepts in GIS and Design », Santa-Barbara, 2008Followed by 2 GeoDesign summits in Redlands in January, 2010 and 2011Many technologies respond to the GeoDesign tasks like Sketch tools, ArcGIS…Many solutions are developed to improve the concept like CommunityViz…
Introduction (1)
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 3
Constraints But GeoDesign needs a more adapted solution: * on-line that supports the collaborative work * wiki-based for editing, managing and consulting the
contributions * with a multimedia wiki to save argumentation of
contributions * manages dynamically the history of contributions allowing
participants to view, analyse, share, and exchange opinions * insures the traceability of user’s contributions: descriptive,
graphical and geometric components * with a simple and dynamic interface to facilitate navigation
Introduction (2)
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 4
Hypothesis * New type of solution called WikiSIG
* This solution is based on:• a content management system (CMS): wiki• a set of GIS functions of Geoprocessing
Introduction (3)
WikiSIG = Wiki + GIS

Many definitions:
1- Miller (2008): « GeoDesign is the thought of process comprising the creation of entities in our geo-scape»
2- C. Steinitz (2010): « GeoDesign is geography by design »
3- Flaxman (2010): « a set of techniques and enabling technologies for planning built and natural environments in an integrated process, including project conceptualization, analysis, design specification, stakeholder participation and collaboration, design creation, simulation, and evaluation (among other stages). GeoDesign is a design and planning method which tightly couples the creation of design proposals with impact simulations informed by geographic contexts »
GeoDesign: Definition
GeoDesign is an emerging term for a technique that combines design and GIS technology
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 8
The Geodesign is:Creative Interactive Collaborative/ParticipatoryDeliberativeMulti-actors: planners from different disciplines, city council, stakeholders, publicMulti-scale: regional vs localMulti-thematic
GeoDesign: Properties
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 9
It includes at leat 4 elements:Sketching: the concept of drawing potential designs or plans Spatially informed models: estimate how various systems will repond to the plans suggested by the sketchesFast feedback: gives near- immediate results from modeling the effects of a sketchIteration: trying many alternatives has advantages
Geodesign: Elements
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 10
Technolgies that support GeoDesignSketch: first key area of support for GeoDesign (e.g ESRI’s ArcSketch (2D) , Google’s SketchUp (3D), ArcSketch of ArcGIS10)Simulation: the examination of design scenarios by simulating their impactsCombination of three dimensional design tools and GIS (e.g GeoDa)
Geodesign: technologies
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 11
Some geomatic solutions could help the GeoDesign processSpatio-temporal GIS: helps to take a collaborative and distributed decisionAugmented reality: offers an environment and tools of collaboration BI technologies (e.g SOLAP): support and enhance the interactive access and analysis of multi-scale and multi-time geospatial information and indirectly to support public involvement in a particular type of PPGIS
GeoDesign: technologies
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 12
Some technolgies developped to do GeoDesign:ComminutyViz: an ArcGIS Desktop extension designed expressly for scenario planningA tool that combines ESRI ArcGIS, Google Earth, sketchUp

No solution can effectively support collaborative work No solution manages proactively the history of
semantic and geometric contributions No solution does geographical traceability of the
object No solution offers at the same time a work in
synchronous and asynchronous mode No solution has multimedia capabilities, where
participants can insert videos, photos, recordings, verbal explanations, etc..
No solution allows open access to public

WikiSIG: Definition
Definition (Ciobanu et al., 2007)
Un système d'information géographique (SIG), construit en ligne (sur l'Internet) par des interventions collectives, lesquelles supposent des interactions entre les participants, puis la fusion et la traçabilité de leurs contributions dans des représentations géospatiales cohérentes et ouvertes à l'enrichissement; ces représentations géospatiales constituent l'expression des connaissances collectives sur un territoire ou sur un phénomène spatialisé donné
New DefinitionUne plateforme collaborative 2.0, appuyée sur un système de gestion de contenus géographiques (SGCG) de type wiki permettant d’assurer la traçabilité des contributions géographiques des participants en les argumentant; et offrant des fonctionnalités d’édition et de création (de type sketch-mapping) et des fonctions SIG (Geoproccesing), et de qualification des contributions, de consultation et d’analyse dynamique de celles-ci, ainsi qu’un accès simplifié et rapide au processus de création « en train de se faire »

A web 2.0 application with wiki A documented traceability of user to ensure not only the
documentation of the design process, but also the access to this process
A simple and ergonomic interface (Geoweb 2.0) A contribution can be considered as an opinion These arguments are the main components of external
qualification of contributions All previous versions of an opinion is considered an integral
component of the object The model of reconciliation of contributions - opinions is used to
support the establishment of a differentiated consensus to validate the final opinion

WikiSIG: Concepts
12/10/2011, 4pmWided Batita_WikiSIG and collaborative GeoDesign 17
UML is:a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systemsuses mostly graphical notations to express the design of software projectshelps project teams communicate, explore potential designs, and validate the architectural design of the software
