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

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

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
