- 8 Data
- 9 Other Topics
What folks used maps for or are interested in:
- Locations in organizing documentation – tools for mapping participation more interested.
- Frustrations of mapping, strategies. Maps are cool, there are fans; civic information.
- Printed handouts, nice!
- Beautiful fold out maps, brochures for us to look at.
- Annual reports.
Geographical Information Systems (GIS)
GIS – Geospatial Information Systems, digital cartography.
- Geography and map making enabled by digital cartography, better and better OS tools.
- Desktop manipulation of data.
- Longitude and latitude.
- Phones with digital maps.
- Sharing data attached to photos, comments, data attached to all tools.
- Humanitarian disaster relief, ushahidi.org which is a way of aggregating disparate data from the web to crowdsource maps.
- Came from Kenya elections when people were monitoring violence at polls, Haiti disaster, posting and commenting can be aggregated.
- Open Street Map is “kind of like wikipedia” of mapping.
- USA public domain data is very good.
- Points of interest, GIS data used by cities in all manner of city processes. Crimemapping, for instance.
- In UK mapping data is owned by the crown, proprietary.
- Wonderful software dev happening in the US, but UK was missing out.
- Then in UK - bike mapping phenomenon started there. Data very good. Places are named, points of interest are named.
- Wonderful things you can do with open data, mapped data, in typhoon in Phillipines
- Important areas bubble up on a map; vulnerable areas tend to be undermapped
- Humanitarian group developed a queue of the most vulnerable places
- Very detailed map developed in short time span to assist in activist navigation.
- Google Maps -
- Mapbox.com – beautiful powerful alternative to Google. Pay – for. Styling.
- Tilemill.com -
- Cartodb – hosted platform, falls between mapbox.com and google maps.
- QGIS – desktop, open source tool.
- Open Layers
- ArcMap – Esri – is the company, trial versions, student versions. Industrial strength tool
- MapInfo – Windows based programs.
Platforms for viewing the map in a mobile sense.
- Mobile is a challenge for spatial information.
- Cartodb you can zoom in and out.
Other Specialized Functions
- World maps, voting maps, d3 has a nice API for doing this.
- AR capabilities?
- Mapbox ID - Open Street Map type platform in java
- Art Project
- Alternative Walking Tours
- History from Below
- City of DC has great publically accessible GIS data; borders of city of limits, stops.
- John used OSM data to make his map.
- Some datasets are not for commercial use, most data requires a credit.
- http://www.naturalearthdata.com has border data, disputed border data.
- maplibrary.org If you are working on Africa, shape files on countries
- Finding the data is often a big part of the challenge – or making the data yourself.
- Insight into clustering? - loads of ZIP codes in Houston may appear as a larger cluster in the map...
- Depends on the story you are telling...
- Location markers can show size, quantity; how to define location markers.
- Leaflet has a plug-in, Leaflet cluster – will replace marker with circle – has a number in it repping number of markers
- Oakland Crimespotting - http://oakland.crimespotting.org/map/ – Stamen Design – big bubbles, categorizing crime.
- Stop and Frisk maps in NYC - http://project.wnyc.org/stop-frisk-guns/ - also, what neighborhoods they were targeting.
- Drops in crime from data visualization?
- Policing smarter?
- Deploying resources in a more specific way?
- Evictionmapping.org project producing evictions in SF happening – using cardodb and leaflet – also animates over time.
- Stamen Design – overlaying crime with trees? Rise of prostitution based upon Uber, private car service network.
- Tree census data – try to determine what factors kill trees along curbs in New York.
- Looking at traffic data, pet ownership, different factors.
- Once trees pass a certain age they are more likely to survive.
- Internal planning maps used by foundations...etc.
- Basket of programs...what countries have been focused upon?
- Map gives such information trend information, awareness of larger geographic area.
- Example: storytelling about divergent kids in relation to cops; schools and stop and frisk info overlaid and evidence of increased numbers of incidents is readily apparent.
- Most organizations have limited resources.
- Mapping urban poverty
- Million Dollar Blocks project came from Spatial Information Design Lab at Columbia Architecture and Urban Planning.
- Rather than mapping location of maps, mapped residents of those arrested for felonies, instead.
- Cost $30,000 to keep someone in prison for a year. Million Dollar Blocks are blocks where at least 33 people lived when they were arrested, convicted and sent to prison.
- Whatever your theory of crime, more resources can be deployed in some areas than in others.
- Focusing on parole offices...how can the parole experience be redesigned to reduce recidivism and make it more humane.
Data Maps From New York, Chicago, and Beyond
- Poverty maps, crime maps
- Geolocated, mapped to intersections
- Used in own advocacy.
- Parents, citizens, can use this
- Journalists as research tool
- City council members can press dept of transportation about intersections
- Very easy to scroll around and see
- Center for Urban Pedagogy
- Pairing artists with projects
- Where does our food come from?
- Through making this process they discovered why it is important to eat locally
- Asset Mapping: People's Atlas of Chicago – people took notes of their place
- Discovering spatial justice issues in process of mapmaking
Other Examples from Around the World
- Geopolitics of health in Lebanon
- Bar charts are ethnic groups
- Circles are public and private hospitals
- Decided not to publish for fear of backlash
- Architecture 2030, floodplain data, city, coastal cities; where sea level rose, what land form would look like.
- Hack to do this on Google Map – Sink My City
- Plotting prisons in Tunisia with videostories of loved ones.
- (Done before The Arab Spring)
- Tunisian Prison Map, created by NGO
- Satellite affected areas over Africa.
- All of Africa covered by satellite access.
- Government policy and state owned telecoms that are keeping people unconnected.
- Cartograms, image is based on the population or the quantity of data...making small and large areas distort the map.
- Project that Amnesty International did: counting houses demolished in Zimbabwe at time of election, for those supporting the opposition.
- Map from Beirut
- Surveillance infrastructure
- Physical security infrastructure
- Militarization of the streets
- When creating a map: lat/long is generated for each point of data or gps data
- Service of converting to lat/long, change logs are available
- Good data is available
- If a more rural or less dense – you can get data from:
- Cloudmade has an API
- Open Street Map data, nicely sliced, too.
- Municipal Extract, subsets of Open Street Map data: http://metro.teczno.com
- Geocoding. Looking at particular state
- Census has zip code shape files available to download.
- Favorite places to get data?
- NYC – DoIT has more and more free data and open data.
- Crowd mapping
- Heat mapping
