SOTMUS 2014 Day 2 Notes

Posted by benbhsu on 14 April 2014 in English (English)

Open Data for Resilience Initiative - Disaster Risk Management - John Crowley @jcrowley jcrowley@worldbank.org

  • Collective memory of deep history - recalling hazards of particular locations
  • OSM as collective memory
  • Geologic cycles can be quite long - thousands, millions or years
  • Underlying nature of risk is changing - cities growing at 5%. Data describe a very dynamic reality
  • Understanding dynamic risks requires better data
  • Need for better data - smaller grid squares - beyond 10km grid down to building polygons
  • Open Data for Resilience Initiative Field Guide
  • Govt data often exists, but need to be collated and made open
    • Fractured over many ministries
    • Political barriers
    • Proprietary formats
    • Worse: PDF scans of "data"
  • Collection on paper, then entering back to OSM using JOSM
    • Building survey form - standard form
    • Teaching community to build their own data, not outsiders
  • Quality assurance
    • Teach people to improve data collection while they're doing it
  • InaSafe - plugin for QGIS - visualize impact models
  • gfdrr.org - OpenDRI Field Guide 1.0 CC-BY
  • Performing analysis and getting it to village-level govt requires a lot of printing
  • The map is a collective memory not only of what is or once was, but what might one day no longer be.
    • What could be, what could be built back stronger?

Building a Community - HOT in Indonesia - Kate Chapman

  • Mapping for preparedness
  • InaSafe - impact modeling software
  • People are core to the community
  • Train people -> those people train others
  • Recruiting posters - new interns had geography background
  • Technical literacy, technical problems (JOSM doesn't run, firewalls)
  • People excited, but don't know how to get started -> train the trainers
  • Train the trainers - little to do with mapping, more about how to teach, build adult engagement
  • 50% of Scouts are in Indonesia
  • learnOSM - step by step guides
  • World Bank GFDRR
  • Field Papers

Inside the Eye of a HOT Activation - Dale Kunce

MapGive - A coordinated campaign for action - Joshua S Campbell DOS

  • Humanitarian Information Unit - research and analysis of humanitarian emergencies
  • Maps are often taken for granted or assumed to exist, when more often they do not
  • @mapgive mapgive.state.gov
  • Connective power of internet has fundamentally changed economics of information creation
  • Lower the bar for new mappers to join
  • Crowdsourcing in government: build relationships with volunteer and technical community, build trust in communities - share imagery - engage local communities - enhance the data
  • American Spaces - outreach centers around the world

OpenStreetMap as Infrastructure - Elizabeth McCartney, USGS; Mikel Maron, Crowd Cover

  • National Map Corps - Volunteered Geographic Information at USGS (project suspended 2008)
  • 2010 project revived
  • Volunteers from 4H, Scouts, retired people
  • Users are peer reviewers after editing 25 points
  • Moabi - collaborative mapping project, DR Congo, forest monitoring
  • Looking for open source mobile OSM editor

I Imported Chicago - Ian Dees @iandees

  • Move to new city, new job -> found open data portal in Chicago -> discussed with local OSM community
  • Still did it wrong - didn't talk to global OSM community
  • License was not compatible - require user to take down data on request
  • Convince open data people of Chicago to switch license to MIT
  • 3 months to import, 1.5 years start to finish calendar time
  • Easier for others to add data once building shapes imported (restaurants, businesses, etc.)
  • Import using JOSM easier than scripting in this case

Open Data and Cities - R.E. Sieber @re_sieber

  • www.geothink.ca
  • What happens to participation when anyone can participate any place?
  • Need grad students
  • How can non-experts be empowered by technology
  • Empowerment of marginalized people and democracy
  • Open Data - data should be freely available for everyone to use, reuse and republish without restrictions
  • Licensing challenges of accessing municipal data
  • VGI - Volunteered Geographic Information is the widespread engagement of large numbers of participants involved in the digital creation of geographic information. Participants are usually non-experts and have little formal coordination with each other.
  • How well do City Open Data and OSM play together? Not well, but getting better.
  • Mapdust - bug tracker for OSM
  • Accuracy is not the first objective. Accuracy is dependent on its use.
    • Credentials provide the accuracy - citizens cannot check every point
    • Eyeballs provide the accuracy - OSM contributors refine the data
  • Neoliberalism - push in cities to deregulate and privatize
    • Govt has less money, VGI looks enticing
  • Andrew Keen's warning - relying on amateurs/volunteers is a problems, govts shed employees and replace with volunteers, if volunteers don't collect enough data, there are no employees to fill gap.
Location: Chinatown, Southwest Waterfront, Washington, District of Columbia, 20004, United States of America
