Neogeography is part of Web 2.0

• Web 2.0 is the “business revolution in the computer industry caused by the move to the Internet as platform, and an attempt to understand the rules for success on that new platform” (O’Reilly, 2006)

• Perceived second generation of web-based communities and hosted services — such as social-networking sites, wikis, and folksonomies — which aim to facilitate creativity, collaboration, and sharing between users.

Neogeography has...

• Transformed prevailing view of what GIS is…– For better or worse– For many Google is now GIS

• Pushed the development of...– Pervasive GIS– “Wikification” of GIS (Sui, 2008)

It is important to remember...

• Neogeography is GIS not GISc– GIScience is about the deeper conceptual grounding of

successful applications the bigger questions about how the world works an applications-led technology is useful for exploring the world

around us

NEOGEOGRAPHY?So what is

Geoweb = Geographic Internet

• “The Geoweb 2.0 is the geographic content and application services of the ‘new’ web. It describes the way people will publish, find and use geographic information” David Maguire – ESRI (2006)

Other elements of Neogeography... names

• Map Mash-ups, Map Hacks, Crowd Sourcing, API’s, Neogeography, geostack, tags, geospatial, geotechnologies and folksonomies

• Nothing new – internet has always invented terms– ‘new economy’, ’cyberspace’, ‘dot.com’, ‘ecommerce’,

’information superhighway’

API?So what can you do with an

CASE STUDY - Environment: Emergency Evacuation

• Major natural and human-induced events may necessitate area evacuations

• GIS can be used to create effective evacuation vulnerability maps based on– Distribution of population– Street map

• Model demand and impact of bottlenecks on speed of evacuation using standard GIS network tools – Adjacency, connectivity, shortest path network calculation

• Open Geospatial Consortium (OGC)– set of standards for Web mapping– Standards tested: Hurricane Response

• Meteorological (remote sensing satellites)• Demographic• Terrain

CASE STUDY - Environment: Emergency Evacuation

Why Google and not OGC

• Bottom up V Top Down– Community building their own inteligence

• Simple to use / build• Immediate• Scalable

Build your own Neogeography

• What are the problems– Can’t share easily– Static– No context (e.g. built

environment) ....• Easy solution...

– Convert to KML and display on google maps?

– NO!Traditional choropleth map

Why “NO”!

• KML Vector Format– Large maps – lots complex vector data– Google maps API – KML limit ~ 2meg

• 2 Possible solutions– Limit complexity of the data shown – keep as vector

• E.g. London MET Police Crime– Use Raster

• Slippy Maps - Tiles

KML (Vector)

Raster - with Gmap Creator

NEOGEOGRAPHYA word of caution about

Profiling for Public Engagement

• The e-Society• 1990s – Technology Use – “Haves” & “Have-nots”

– Digital Divide• 2007 things are radically different

– Usage & Engagement increasingly more complex• Created a classification which consisted of 8 Groups &

23 Types. – Links to Postcode.

Profiling for Public Engagement

Members of this Group often acquire their competence in the use of information technology at work, since many of them are young people working in junior white collar occupations in modern offices. They are keen to become more expert in the use of new technologies and to use them for new applications. Many spend time browsing the Internet but without necessarily making many transactions. Many members of this Group work in large cities and may be starting a life in a house that they own, typically in one of the cheaper inner suburbs. Their use of the Internet at work may be a practice that their employers may be keen to control or reduce.
