Spring 2011: Initial Thoughts on a “Green Map”

January 22, 2011

I have compiled ideas generated in class on Wednesday, and included some additional ideas about our green map project.

There are details below regarding audiences, form & design, collaboration, and content.

Veronica Malencia (who is in our class) and Alecia Welu will focus on the general green map and its content as part of an independent study this semester. Students in 355 can contribute to that part of the project, but it is not a primary focus.

Students in 355 will work (alone, or in groups) on a “substantive” content project. I list a few independent study projects that will be part of our overall green map project, along with some ideas for other projects.

Green Map Audiences:

  • Potential OWU students: distributed by Admissions: appeal to students with interests in social and natural science environmental focus in studies; general appeal (“OWU is a Green University”).
  • Existing OWU students: informational, engaging (get people to do stuff), and to get students to think about how what they do impacts the environment. Short-term residents, 18-21, etc.
  • OWU faculty and staff: informational, engaging (get people to do stuff), and to get faculty & staff to think about how what they do impacts the environment. Longer term residents, 20s-80s, etc.
  • Delaware community members: informational, engaging (get people to do stuff), and to get faculty & staff to think about how what they do impacts the environment. Longer term residents, children t0 elderly, etc.

Green Map Form & Design

  • Paper map: Green Map Assemblage: one main OWU, Delaware City, and Delaware County map with general content (22″ x 17″ or larger) with series of smaller separate printed maps, brochures, cards, etc. (11″ x 17″ or smaller). Combined together in folder. Additional elements can be added in the future.
  • Online map: map mashup from template vs programmed/designed site vs app.
  • Graphic/cartographic design of project: does it need to tie into “look” of other OWU sponsored materials?

Collaboration on Content

  • Geog 355 students (building on some previous work)
  • Geog 360 (Environmental Geography) students
  • OWU Sustainability Task Force (faculty, staff, students)
  • Specific faculty & staff at OWU
  • Sustainable Delaware (community)
  • Earth Day 2011 (mid to late April)

Green Map Content: Overarching Issues

  • What does Green mean? Compile list (what does it mean to us and to our audiences) and include aspects throughout our Green Map project.
  • Relate audiences to content: what will appeal to each audience?
  • Relate final form to content: how does end product shape class research on topics?
  • Define relevant collaborators

Green Map Content: General Content

  • Outsource: Veronica Malencia and Alicia Welu (independent study)
  • Main (22″ x 17″ or larger) map. Campus and Delaware City on one side, Delaware County on other side.
  • Compile categories of general content (recycling, food, transportation): Location of sustainable efforts (action), recycling facilities, energy-efficient buildings, alternative transportation, Green organizations, farmer’s markets, local food sources, re-use stores, sustainable living, Green business (who decides?).
  • Include content included in sustainability assessment measures (CSAF, Sustainability Report Card).

Green Map Content: Substantive Content

  • Focus of course projects: results of study and analysis of “green” topics
  • Majors in course: will shape content of projects: Economics Management, Environmental Studies, Geography, Geology, Physical Education, Zoology.
  • Topics: preliminary ideas
    • Outsource: Food: Brandt McDonough, Jack Schemenauer (independent study, StAP): sources of “green” food, vegan, vegetarian, organizations, cooking, recipies
    • Outsource: Transportation: Bobby St. Clare (independent study): faculty and staff “drive shed” and analysis of student driving, biking, walking patterns
    • Outsource: e-Waste on campus: Tim Schmidt (independent study)
    • Campus/area ecosystems & wildlife (birds, fish, etc.): project and cards from Spring 2010
    • Connections between ecologically important areas (existing and proposed)
    • Development of “Curricular Trail” like Mt. Holyoke College. We have somewhat less ecologically substantive areas, but still may work: tie together existing study/ecological areas on campus, indicate what is known about them, propose new areas to study (such as Olentangy River).
    • Map “grey” and “black” (bad stuff) vs. “green” areas on campus
    • Olentangy River: low-head dam removal, ecological impact, drugs in river, “blue way” and riparian issues: linear map
    • Storm drains and surfaces: see maps in this PDF
    • Global OWU: map connections: where what you eat is from and impacts, etc. Economic/political ecology
    • Development and green space in area (old green space project, updated, DALIS): enhance with evaluation criteria such as Forestland Evaluation and Site Assessment (FLESA) + GIS tools
    • Micro-geography of environmental topics (a la Green Man Moop Map)
    • Cool To Do Not So Far from OWU: see last project in Geog 360 Projects Fall 2010
    • something for econ people: ?
    • something geology: ?
    • something for phys ed people: ?

Some updated thoughts… Wednesday, January 26:

  • diverse issues affecting the Olentangy River
  • plan “Olentangy River Expedition” for spring: canoe or wade & document (photos, etc.) from dam (north) to county boundary (south)
  • ecological issues: low-head dam removal, pollution/runoff, water testing, animals, plants, development, etc.
  • action: use issues: prospects for recreation: a “blueway”

3. OWU Green / Curriculum Trail

  • Rachel Bowes, Meredith Palmer, (Joanne Neugebauer)
  • research & map a proposed “trail” connecting key habitats, ecosystems, and study areas around OWU; develop a proposed trail (proposed stuff)
  • what is extents of area covered
  • compile various “ecosystems” or habitats on and around campus, study areas used for classes, etc.
  • compile related birds, animals, trees, plants, insects, etc.
  • trading cards
  • action: get people out and noticing and understanding the environments near campus

4. Earthly Delights around OWU

  • Alexandra Bishop, Mary Boatwright
  • map with places near OWU to go and do green stuff: camping, canoeing, fishing, hiking, biking, etc.
  • plan expeditions for all activities, compile details from start to finish how to go about doing these activities
  • activities should be diverse, and in diverse environments, walkable, bikeable, and drivable
  • stress learning about the environmental issues surrounding each activity
  • stress health benefits (physical, mental)
  • action: get out in the environment off campus

5. Global OWU Environment

  • Christopher Demecs, Neil Michaels, Robert Striler
  • Map stressing the global environmental impacts connecting OWU to our region, state, country, continent, world. Positive and negative examples. Examples at different scales.
  • generate a series of ways OWU is connected into a global ecosystem: examples
    • food: banana (connection to rainforest destruction in Costa Rica), factory farms (impact on environment here of food shipped all over US)
    • transportation: data on vehicles registered on campus; CO2 impact; Honda Plant; CO2 generated by student, staff, and faculty flying
    • energy: car dealership wind turbine, OWU geothermal
    • vegetation/plants: native tree nursery (replacing non-native tree species)
    • water: prescription drugs, agricultural chemicals in water
    • waste: sewage (where does it go), garbage, e-waste (to Africa? China?)
  • action: think about and act in an environmentally responsible manner

6. OWU Transportation

  • Nicholas Chilkov, Zachary Frentsos
  • Map of “drive-sheds” of faculty, staff in central Ohio with calculations of CO2 and other impacts
  • Map of student movement on and around campus: track walkers, bikers, drivers & environmental and personal (calories, etc.) impact
  • Action: draw attention to driving; encourage alternatives

7. Eating OWU

  • Sophie Gage, Zack Kaminski
  • Map and information on where to get “green” food, where to prepare it (kitchens and utensils), how to prepare it (recipes) and food socialization.
  • Action: eat for the environment and yourself

8. OWU and Delaware Gak Map

  • Michael Davidson
  • Map and information on water, soil, air contaminants, bad food choices, pollution sources, cars and traffic dangers; focus on what you as a person are exposed to, the chances of bad stuff happening, etc. Smoking.
  • Action: get depressed, don’t come to OWU, etc.

Thoughts on a OWU / Delaware Green Map

February 15, 2010

Deadline 1: Delaware’s Earth Day, April 22: table w/preliminary Green Map parts & gather feedback

Format: Series of maps (5.5″ x 8.5″, 8.5″ x 11″, 11″ x 17″) that fit together + and web site / app

  • “dissected green map” – page or smaller size maps that fit together into a poster; expandable for future projects, trading card idea for promotion (“collect them all!”) on the reverse of some maps, or as smaller parts that fit into the entire layout (subdivide the 5.5″ x 8.5″)
  • digital: development platform? long term maintenance?
  • set up web site for “crowdsourcing” local environmental information?

Audience: how might different audiences shape the content of the map?

  • Delaware community members, kids vs adults
  • OWU students, faculty, staff
  • potential OWU students: using green amenities to promote OWU (Admissions Office)


Please get me corrections, additions, links to your blog postings on projects ASAP


Major Green Map Components Spring 2010

1. Green Map of OWU & Delaware: centerpiece of project

Elizabeth Lambert, Alex Linde, Michelle Lee (“Green Businesses” preliminary proposal here)

  • 11″ x 17″ two-sided
  • side A: traditional Green Map of area
  • side B: additional information, details, directory, activities

Procedures for collecting and assessing data for this kind of Green Map (initial explorations of “Green Map” earlier this semester).

Web/Internet component?


2. Bird Map of OWU & Delaware

Paul Gruber, Kristin Kovach, Kristen Lear, Michelle Lee

Preliminary proposal here.

Side A: map of habitats and typical bird species (extent of coverage?)

  • Important: the habitat map should be applicable to other species of animals as well as plants; determine the procedures for creating a habitat map, define the extent (how far should the map extend – all of Delaware, or campus and near campus?).
  • Future projects: can add additional animals, plants to habitat map, and update habitat map if need be

Side B: bird trading cards (problem is that side A would get cut up).

  • Alternative: fit cards in the many smaller spaces in the entire poster layout.
  • Activities: tie to Decker Arboretum, activities for K-12 (bird education)

Web/Internet component

  • PDFs of map and cards
  • use interactive web site to collect information on bird sightings (crowdsourcing)


3. Walkability and Bikeability Map of OWU and Delaware

Dani Beauford, Tim Schmidt,

Content: walking vs biking vs driving times, calories vs fuel, map a series of car paths (GPS)?

Size: 11″ x 17″ (?)

Public transportation: DATA and connections to Columbus (flip side of map?)

Web/Internet component?


4. Green and Black Map of OWU & Delaware

Kyle Karczynski & John Romano (?)

Content: one side: all grass, woods, etc. areas on campus and in Delaware (near campus?), with flip side a black map (gray map) of all paved areas, roof tops, and also any nasty toxic sources (EPA Toxic Release Inventory).

Size: 8.5″ x 11″ (?)

Web/Internet component?


5. Utility Costs & Building Trading Cards

Bibhas Acharya, Jack Stenger,

Content: based on utilities data, calculate some appropriate data for mapping – take into account number of students using buildings, etc. Rapid assessment of energy loss in key buildings (past energy audit, new audit planned?). Building cards that stress green and not so green characteristics, plus “activities”  that would help save energy in specific buildings.

Size: 11″ x 17″ (“where the students are” data on flip side?)

Web/Internet component?

Projects from Geog 360 that might be part of the Green Map

Wednesday February 17: Project Proposals Due!


Project Proposals: Detailed Plan of Action (Based on Mitchell Chapter 1)

1. Frame the Question

  • pose your question: what exactly is your project aiming to do?
  • where are endangered ecosystems in Delaware County?
  • where are potential recreational trail corridors in Delaware County?
  • how can viable OWU food waste be efficiently distributed to area food banks?
  • where does the food sold on campus come from, and what are the consequences of our consumption of these foods?
  • who is your audience?  what is your ultimate goal?

2. Understand your Data Needs

  • what is the context of your question?  who are the experts?  literature, people
  • what do you have to know about the context of the question to answer it?
  • what is an endangered ecosystem?  what are specific examples?
  • what are the goals of recreational trails?  what do they connect?
  • how is food waste reuse assessed and how is it collected?

3. Find or Create your Data

  • what data is available to help answer your question?  cost? compatibility?
  • what data do you have to generate yourself? easy vs. difficult vs impossible
  • necessary to have the data or a plan to create it (with necessary technology)

4. Process the Data: specific analysis

  • apply ideas from readings & software tutorial to your project
  • ex) generate endangered areas by comparing areas defined as important ecosystems to their closeness to recent development
  • ex) generate potential trails by generating important points and areas to connect; and determining feasible paths between those points; relate potential trails to property ownership and other factors
  • ex) generate a plan for distributing food waste from campus to area food banks
  • ex) analyze the global impact of specific food consumption on campus

5. The Results

  • vital part of the process: communication and advocacy
  • generate a map (with a database) and use it to present results
  • ex) map of endangered ecosystems in Delaware Co: distribute to ??
  • ex) map of potential trails in Delaware Co.: planners, bike clubs, etc.
  • ex) a map that guides distribution of OWU food waste
  • ex) map of the global impact of what we eat

Class Project Ideas: Feb. 2, 2009

February 11, 2009




I was moving some piles of junk and came across a 1934 U.S. Public Works Administration book on Mississippi Valley public works projects (Report of the Mississippi Valley Committee of the Public Works Administration, October 1, 1934).  The book is full of maps and other information graphics influenced by Otto Neurath’s picture language, isotype.  Isotype is visually distinctive and activist and populist in intent.

Some examples of the isotype “language” from a 1937 article by Neurath:

isotype_lang1 sotype_lang2 sotype_lang3 sotype_lang4

It struck me that we could use isotype inspired maps and graphics for our “dis-orientation” guide and poster.  We are copying the idea of the UNC map, but with an entirely different look.  Isotype – with its activist and populist bent – seems to be very appropriate.  And funky-retro.

Further, I think we can roll the majority of class projects into this poster, or at least some part of each of the projects, so we have a green/sustainability oriented dis-orientation map.  Isotype is certainly related to cartography and GIS and the goals and intent of our projects.  Further, isotype design was at its peak during the 1930s – the last great depression.  That corresponds with the current not-so-great semi-depression.


Otto Neurath (1882 – 1945) was a philosopher, sociologist, and political scientist. One of his many concerns was education, and in particular, enhancing the understanding of statistics and other numeric data.  To this end Neurath, Gerd Arntz, and Marie Reidemeister created the pictorial language isotype. A few examples open this posting.

We may want to have the last set of readings / student presentations focus on the ideas behind isotype – thus focusing on the way we plan to present our work to the eager public.


A few interesting isotype & Neurath resources to look at:

The Isotype Institute carries on the tradition of isotype, and includes many isotype graphics to look at.

1930 Atlas of Gesellschaft und Wirtschaft (Society and Economy): big PDF of entire atlas.  Sybilla Nikolow discusses the atlas in her article “Society and Economy: An Atlas in Otto Neurath’s Pictorial Statistics from 1930.” (PDF)

Ellen Lupton reviews the history and significance of isotype in her article “Reading Isotype.” (PDF)


Neurath and the Vienna Method of Picture Statistics (PDF).  A chapter out of an e-book called Speaking of Graphics An Essay on Graphicacy in Science, Technology and Business by Paul J. Lewi.  Seems like a nice overview of the history of isotype and its characteristics.

The DADA Companion has much information on design and art related to isotype.  Search for “isotype” or “Neurath.”

A new book should be out in April of 2009 called The Transformer: Principles of Making Isotype Charts by Marie Neurath and Robin Kinross.  A copy is ordered for our library.

Gerd Arntz Web Archive. A super collection of thousands of isotype symbols designed by Arntz.  All seem to be free to use.  The site also has a breif biography of Arntz.

gmdh02_00158_0 gmdh02_00094_0gmdh02_00045

Austin Kleon’s blog on graphic design has a nice posting on isotype, comics, and information graphics design. Search the blog for other isotype references.

The web magazine Mute has a feature called The Dutch Are Weeping in Four Universal Pictorial Languages At Least that reviews a series of contemporary exhibits that focus on isotype and related ideas.  One exhibit called After Neurath has a significant amount of information and links.

The New York Times summarized 2007 US and Coalition member deaths in Iraq in a isotype-esque chart (click for larger version):


Stroom De Haag writes (in the online magazine Archined) about Neurath as the “grandfather of open source.”

Lots more out there…
