9. Politics of Maps
● What information was recorded on a map?
● Who made/drew the map?
● Whom was the map made for?
● Maps produced by the rich, the powerful, and to
demonstrate certain views from certain dominant
cultures (e.g., religions, empires)
● In the Taiwanese context, as a colony of various
different powers (e.g., Spain, Holland, China, Japan,
perhaps also the US), the maps were made by these
empires. Majority of current maps are made from the
Chinese perspective.

17. Cartography 2.0
● Open Source technologies + free / open access
mapping data and geographical information
● User-generated and user-participatory
● Freedom to distribute, copy, modify, read, and re-
distribute the mapping data and technologies
● Customisable and extensible
● Ideally, everyone can make maps for their own
needs! ( 地圖學生活化 , 科技公民參與 , 常民 / 在地知
識成為地圖學的一部分 )

18. OpenStreetMap Community History
● 2004 July, founded by Steve Coast
● 2006 April, a foundation was established to encourage the
growth, development and distribution of free geospatial data and
provide geospatial data for anybody to use and share.
● 2006 December, Yahoo confirmed that OpenStreetMap could use
its aerial photography as a backdrop for map production.
● 2007 July, the 1st The State of the Map conference was held
● Number of users to date 341630

19. Highlights from 2010
● Haiti and “Crisis mapping” ( 災後重建地圖學 )
● Disability – mapping for the blind
● Cycling Maps (Open Cycle Map, Cambridge) –
perspective different from drivers' ones (or walkers'
maps, mountaineers' maps) ( 汽機車駕駛人的主流
價值 , 有車階級 )
● Overlaying data onto maps (e.g., tree data, open
public information, poll results, crime data)
● Diversity ( 多元價值與多元文化的呈現 )
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
21. Crisis Mapping
● Ushahidi.com is a free and
open-source platform. Its initial
creation in Kenya was to
collect reports of violence in
late 2007 and early 2008 in
the wake of contested
elections in Kenya.
● The platform allows people to
easily submit reports via the
web, email and SMS. It then
plots the reports on a map.

23. OSM for the Blind
● http://wiki.openstreetmap.org/wiki/OSM_for_the_bli
● http://www.blind.accessiblemaps.org/
Software and maps for the blind is
usually expensive and also outdated.
The blind community can help
themselves update the maps.

24. Open Data & Maps
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
25. Technical implications
● Open source – both the map and software are never finished
products; they are perpetual beta (always under testing and
improvement)
● Fix the problems as you spot them.
● User friendly tools such as Potlatch, the web-based map
rendering interface is important for less tech-savvy people
● Transparency
● User-led innovation
● Democratic design, public engagement and participation
● Customisation
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
26. Cultural Implications
● POI (Points of interests)
● You can define what is important (to be
included in the maps) and how to name a place
(the name tells a lot! e.g., 自由廣場 or 中正紀
念堂 ) → Your voice counts.
● Is Taiwan part of China?
● Encouraging local cultures and creativity
● Visualise and/or organise your own content on
a map using free / open content
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
27. Economic Implications
● Cheaper/Gratis maps
● Maps are free to be used → no need of
acquiring permission
● Lots of different business models built on OSM:
e.g., Bing, AOL, Ito, CloudMade
● New business models built on open content,
open data and open source technologies

28. Locative Media
● http://www.maxamundo.com/cms/index.php
● Geo-referenced information, geo retailing,
location-based
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
29. Educational Implications
● 鄉土教學 (Knowing your neighbourhood, Community engagement)
● e.g., map the school, map the students' homes, map local monuments
and POIs (e.g., public telephone boxes)
● Start early to learn how to produce a map from scratch (if you start late,
everything is mapped)
● Relevant to the students → Can do at home after training & Self
motivating
● Good preparation prior to class important – so many details need
attention (e.g., health & safety regarding field trips 戶外教學 , school
computers need updating, installing Firefox, GPS did not work,
performance problems with the OSM site, Login Process to Mapzen )
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
30. Educational Implications
● 鼓勵孩子探索人與環境的關係
● Preserving local cultures (documenting local names,
indigenous names)
● Collaboration (peer production 同儕創作 ), not just
competition
● Acknowledgement, no plagiarism (unlike 山寨文化 )
● No pirate software – use free software
● Technologies are not black boxes; they can be opened up
and reconfigured.

31. Social Implications
● Building communities (a global OSM and many local
communities)
● Establishing identities (OSMers and local
communities)
● Mapping parties (how to best organise mapping
parties)
● Social gatherings
● Mutual learning and knowledge exchange (glo-cal)
● Memory sharing (memory of a place, of a story)

33. Conclusion
● It's your Map. Get involved!

34. Point/Place of Interests (POI)
● POIs are places where you'd like to visit. Along with other information (e.g.,
description, address), each POI has a named set of coordinates which refer to a
specific point on the earth – made up of an intersection between a latitude
number and longitude number.
● Why are POIs important?
● POIs help you to record, present and locate information on a map
● POIs represent your interests, your preferences, your memories, your identities
● Why creating your own POIs?
● POIs information missing, incorrect or out-of-date
● Most POI data generic
● To ensure accuracy and adequate representation of the locations of stuffs (things,
monuments, attractions, restaurants, services...)
● How to record POIs?
● Standards and agreements on terms → Compatibility
● Privacy issue - where you've been, what you've created, what you're interested...
Mapping Party, Kaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org
35. What POIs can you create?
● Favourite places – Share your favourite spots (restaurants, parks, pubs,
shopping, cafe, tourists attractions,…almost anything!)
● Bank/Cash machines – Ever have trouble finding a bank/cash machine
that is from your bank?
● Post Offices
● Gas/Petrol Stations – Have a credit card with one of the gas stations
you use? On the road, you often have no idea where your preferred gas
station chain is located.
● Car Park – with opening times and fares (if street parking, rules)
● Wedding – Getting married? Create a POI Group with the church,
reception hall, hotel for guests, park photo location, tuxedo rental place,
spa, hairstylist, and the store you registered at. Make it available for all
your guests so no one is late!
● Traffic and Construction – When driving, get a heads up on locations of
speed and red lightKaohsiung, Taiwan, 2 January 2011 | Yuwei Lin | http://www.ylin.org avoid
Mapping Party,
cameras. Find out construction zones and
36. What can you use POIs for?
If you are a business owner -
● Sales & merchandising targets – provide specific easy-to-download
sales locations for your reps to visit and comment on
● Availability – set targets for your reps to expand product availability
● Tourism – promote tourist locations and expand the health of your
partners and economy
● Real Estate – help your clients locate properties with ease
● Business Visitors – set out a trade or facilities visit to key company
or competitive locations
● Geo-retailing (Anonymous Direct Marketing (ADM))
For everyday use
● Going on vacation? Browse through POIs for some great ideas!
● Events – Look up the locations of the places where events are held.

用來紀錄實察點和實察路線的經緯度坐標 , 方便之後匯入
OpenStreetMap 中展示。
● GPS-enabled devices e.g., GARMIN, TOMTOM,
PIONEER AVIC, MIO, NAVMAN, MAGELLAN, Google
Earth, GPS Exchange, LG Electronics, Blaupunkt, More
under development
● Digital camera ( 數位相機 ) - 用來紀錄各實察點的地理景
觀。
