  1. The Big Board A collaborative environment for geography

  2. A motivating example • A cross institutional team is assembled for a community-focused study of the historical residential segregation of the city of Asheville N.C. (including redlining and urban renewal}: • Asheville (Priscilla Ndiaye, Southside Advisory Committee chair) • Duke (HASTAC, iiD) • UNC (SALT lab) • RENCI • Funded by: • NARA / NSF • Duke Bass Connections / Duke iiD

  3. The problem • Study of urban renewal involves compiling • Pictures • Testimony • Primary sources from city records • Census data • Crowdsourced data about individual sites • And putting it together

  4. How to put it together? • Maps are a natural method for • understanding the changes across entire neighborhoods • browsing the available records • But GIS systems fall short on • Displaying unstructured data • Allowing interactive collaboration

  5. The Big Board • A collaborative mapping platform focused on • Real-time collaboration • Linking together unstructured data • Providing a platform for domain specific extensions / plugins that aid collaborators

  6. Overlay data from the web

  7. Draw, add, edit, search annotations

  8. Persistent, interactive chat-room

  9. Display and compose unstructured data in a Wordpress-like environment

  10. Enabling technology: Geoanalytics • RENCI Geoanalytics is a cyberinfrastructure for geographic data. • Digest data from disparate data types • Serve unified API through OGC web-services • Publish data through a CMS like interface • Provide styled maps • Provide framework for interactive web and mobile application development using geography

  11. Geoanalytics’ strengths • Big data • Implement a few methods in Python, adapt to a new datatype • NoSQL stores like MongoDB, Cassandra, Redis • Specialized data e.g. timeseries on irregular grids • Native support for time-series and versioned data • Web and mobile-web infrastructure • Quickly develop geography-enabled web apps • Analytics • Use an interactive Python environment over the web to explore data with MatLab like tools

  12. Other applications of the Big Board • Decision support for • Emergency management • Public policy • Public health • Epidemiology
