Title Text
GIS and spatial media
(Ricker, 2017)
Knowledge Politics
Political Power
"...knowledge politics to be shaped by deeply institutionalized tendencies in planning and policy making to grant greater weight to knowledge expressed as quantitative data or represented in cartographic forms."
Data Driven Decision Making
(Elwood & Leszczynski, 2012: 545)
Geoweb
-
interconnected tools and spatial data available on the web spanning multiple geographic regions (Lake and Farley, 2007)
-
Revolutionized spatial data (Sui, 2008)
-
but not democratizing it (Haklay, 2013)
-
Provides access to satellite and aerial imagery! (Goodchild, 2007; Harvey, 2014; Kingsbury & Jones, 2009)

Opportunity to contribute Volunteered Geographic Information (Goodchild, 2007)

Spatial Media
Elwood & Leszczynski (2012) New spatial media, new knowledge politics. Transactions of the Institute of British Geographers (38): 544-559.
"Mediums or channels that extend our ability to interact with and create geographic information online" p 544
"From expert to everyday"
(Elwood & Leszczynski, 2012)
Public Participatory Geographic Information Systems (PPGIS)
Geoweb
Spatial Media
Maintain a keen awareness as to not reproduce inequalities. Active engagement in effort to use these technologies to combat inequalities (Elwood, 2015)
{
}
Participatory Mapping
means to illuminate social and environmental injustices
co-construction of knowledge= Better understanding of HAZARDS?
promotion of self and critical awareness that leads to individual, collective social change
Participatory Action Research
"moment of translation
transforming experiential, testimonial and qualitative forms of knowledge into quantitative aggregated or abstracted forms" (Elwood & Leszczynski , 2012: 548)
Photovoice
Purpose
Method by which participants identify, represent, and enhance their community through a specific photographic technique
- Identify community assets and deficits
- Use photography to draw attention to a social issue
- Induce change by informing policy makers
Tell me, I forget.
Show me, I remember.
Involve me, I understand.
-Chinese Proverb (Paulos et al., 2009)
Citizen Science “scientific work undertaken by members of the general public, often in collaboration with or under the direction of professional scientists and scientific institutions.” (Haklay, 2015)
Examples of Student Work: Capstone Project
Scientists: Julie Masura and Cheryl Greengrove
Students: Chris Vandenburg, Dana Scott
•UW, NOAA, Center for Urban Waters, Sound Experience
MICROPLASTICS
Quantifying microplastics
Data Entry For Citizen Science?
Who is the end user?
Who is entering the data?
What is going to be done with data?
Cost?
Technical knowhow of the developer?

Aerial Photovoice
- evokes emotion
- representations of place
- What if we used it for something more important?
Digital Maps! Digital Globes offer basemaps for participatory mapping. But they also control temporal and spatial resolution of those basemaps
Putting a UAV in the hands of a community, could they monitor...
- Community changes through the course of a day, season, year...
- Acute changes - landslide event, urban encroachment
- Gradual changes - land use change, urban growth
- Ecosystem services
- Access to water resources, refugee camp movement
- Habitat loss...

Social
Implications
Similar critiques of GIS
and mobile spatial media (Elwood, 2008; Thatcher, 2016)
Privacy (Curry, 1997)
- Geoweb transformation of the social contract around privacy – societal agreement (Elwood, 2015)
Access to technology (Obermeyer, 1995)
Risk of Re-enforcing inequality
Legality
- Decline of the public sector - private sector leading
- "Enthusiasts" can fly, not governments
- International regulations vary dramatically

OSM for disaster PREPAREDNESS
Student Project: Pull from OSM
Streets:
•*Cobblestone streets
•*Roundabouts at intersections
•*One-way streets
•Narrow two-way streets (because of street parking, only one vehicle at a time can pass through in either direction.)
•Speed bumps on streets
Residences:
•*Single-family home; Duplex, Triplex, or Apartment Building
•Year built
•*Number of floors
• *how many apartments
•*Location of Gas Meter(s)
•*Location of Electric Meter(s)
•*Location of Stationary Propane Tank(s)
•*Location of Stationary Heating Fuel Tank (Heating Oil)
•Solar Panels of Roof? (Y or N)
•*Presence of a detached garage

Data
Ambiently collected?
Actively collected?
More research questions!
What knowledge is transferred
through the data entry/collection process?
Through the map interaction process?
Conclusion & Future
Maps are political
INVITE PARTICIPATION
Work with communities
Opportunity to establish ethical standards for UAV usage
DATA PREPAREDNESS AS DISASTER PREPAREDNESS
- Illuminate social and environmental injustice
- Relevant Temporal Resolution
- Enhanced Spatial Resolution
- Increased coverage
- Complement existing research methods
- Opportunity to establish good practice with community engagement
Participation sparks critical thinking during each step of the process
Data Day Dreams
Challenge
Participate in Citizen Science!
Knowledge Discovery!
Thank You.
