Example: Create maps and share via link

GIS as (social) media (Sui and Goodchild 2011)

Example: Create maps and share via a range of social media outlets

Example: Create special interest groups, comment and rate maps

Example: Add twitter feed to keep map users up to date

PGIST & CyberGIS: Integrated analytic-deliberative environment

Structured Participation Toolkit Goals

Large-scale, asynchronous participation Structured analytic-deliberation Consensus-building & decision-making Open, transparent decision repository Participation metrics for reporting

INTELLIGENCE DESIGN CHOICE

REFLECTION

PGIST Challenge

• Monolithic web application• Local client-server architecture• Technology specific

X Web Services? No, much of the functionality is in the GUI. Need a Pluggable GUI Framework that can support cross-domain and cross-platform communication. Processing and persistence layers are hosted, similar to SOA.

• Pluggable functionality• Remote client-server architecture• Technology independent

How can the CyberGIS Gateway be expanded to support collaborative problem solving?

SPT Solution

JSOP

JavaScript Object Notation – PaddedServer response injected in the <script/>Doesn’t violate browser security.

SPT – Proof of Concept

var keywordStore = Ext.create('Ext.data.Store', { id: 'keywordStore', model: 'Keywords', proxy: { type: 'jsonp', }}

var feedbackText = form.findField('feedbackTextArea').getValue();keywordStore.getProxy().url = 'http://localhost:8080/dwr/jsonp/BCTAgent/prepareConcern/' + feedbackText;

keywordStore.load(function(records, operation, success) {var checkboxconfigs = [];for ( var i = 0; i < records.length; i++) {

for(var j = 0; j < records[i].data.tags.length; j++){

checkboxconfigs.push({name :

records[i].data.tags[j],inputValue :

records[i].data.tags[j],boxLabel :

records[i].data.tags[j],xtype : 'checkbox'

}

Simple HTML page, with link to Ext JS4 file

Client data model & store

Dynamic GUI generation

Remote server invocation

• Identify SPT capabilities from PGIST web applications

• Determine which functionality to bundle as ExtJS 4 GUI widgets

• Integration of SPT into CyberGIS Gateway• Runtime configuration and deployment of

participation workflow

Next Steps

Support the development and evaluation of "Capabilities for Science of CyberGIS and Science with CyberGIS”.
