Some questions...How are WWW data about acity?What about the quality?Are they useful?Can they be improved?
pre-Digital Cities versusSmart Citiespre-Digital City: ¿Able to consume data?Smart City: To produce and consume its own data

Different data sources forMAS simulation Extreme Urban dynamics Explore every WWW information about both Urban evolution under the city and the event exceptional circunstances Data comsumption by MAS pre-Digital city: New Orleans Extreme dynamics: Katrina hurricane (2005)
Why this event?First, Katrina is one of the There exists a big amountmost destructive of data source and Webhurricane suffered by a services associated (ordeveloped country, USA consumable by) Geographic InformationThe extent of damage Systems with publicinvites for a macroscopic accessanalysis of the incident
Bounding the scopeIn order to evaluate the In some cases aquality, accessibility and reparation of defﬁcentusefulness of I2U data is necessaryIt considers only I2U Mainly, data from globalaccessible by WWW, information systems (orInternet or deep Internet U.S. Agencies)( that is, accessible via more speciﬁc data maysearch forms) limit the reusability.
Why MAS?MAS based simulationmethodology allows toestimate how affect dataquality to each module of I2U main ﬂow for thisthe system: simulation Statistical results from surveys useful for agents- citizens behaviour.

ConclusionsI2U information ﬂows is used, in this work, to simulateurban phenomenaSimulation needs digital information from cities and itsown feedbackPrevious and exhaustive information analysis andclasiﬁcation its fundamental to start any kind of urbancloud computing
Future WorkUse Complex Systemsmethodologies to analyse andto compare events andsimulationsTo detect emergentphenomena in digital cities bymeans of simulation and Datamining
