NeoGeography Does it really exist?
Began as an expression of Web 2.0 applied to maps AJAX, JavaScript APIs, RSS Craigslist mashup / Chicago Crime Maps *
Democratization of geographic tools
Web Developers discovered Geography…
What about Geographers discovering the Web?

What is Web 2.0?
“a transformative force that’s compelling companies across all industries towards a new way of doing business characterized by harnessing collective intelligence, openness, and network effects”
--Tim O’Reilly

What is a GIS?
A digital representation of the earth, structured to support analysis (Dobson, 2007)
Automated systems for the collection, storage, retrieval, analysis, and display of spatial data (Clarke, 1995)
Should also include dissemination
Composed on software, hardware, and people

GIS 2.0: A Reformulation
Ubiquitous communication Widespread wired and wireless networks (voice and
data)
Device convergence Mobile devices increasing in power and functionality Phone, camera, GPS, form-based database input,
cellular, wifi
Cloud computing SaaS, PaaS, IaaS Network-driven commoditization of IT

GeoStacks Process Driven
Neogeography Capture Produce Communicate Aggregate Consume
GIS Collect Store / Retrieve Analyze Visualize Disseminate
Essentially the same process
GIS + Web Publishing

Geography 911 Project Goal: Design and implement a neogeography
application that allows users to access, input, and modify spatially relevant data on a map of the University of Kansas Lawrence campus.
Scope:... provides to the community the means to share geotagged content and geographic data from multiple locations in multiple formats on the internet. Content and data can be uploaded into or embedded on
individual layers then be displayed on a map of the Lawrence campus.
Examples of content may include photos, videos, text comments, vector-style locations (such as routes and “push-pins”), or user information

Project Architecture (Input) How do people get data into the system?
Data Collection On-screen digitize, SMS, email, forms How to capture existing authoritative data?
RSS, geocode
Storage / Retrieval Leverage geographic nature of data requires spatial
data types PostGIS::ArcSDE
![Page 23: Geography 911: NeoGeography GIS 2.0 and Software Toolkits](https://reader035.vdocuments.us/reader035/viewer/2022062520/56815995550346895dc6dcb8/html5/thumbnails/23.jpg)
Project Architecture (Output) Once data is in the system, how do people interact
with the information?
Visualize Web Map Server (GeoServer, MapServer::ArcGIS Server)
Styling (SLD, MAP files::ArcMap) Map Window (OpenLayers: :ESRI JavaScript or Flex,
Google) Widgets (GeoExt::ESRI JavaScript (Dojo) or Flex)
(Layers, Queries, Analysis, Draw tools…) Base Layer Data (Open Street Map::ESRI, Google,
Microsoft)
Storage / Retrieval SQL statements for user queries Spatial analysis functions intrinsic to spatial database

Project Architecture (Output) Once data is in the system, how do people
interact with the information?
Disseminate Publish data in a several different formats Web Services (OGC), KML, CSV, text…. RSS, SMS, email updates
