In this talk, I will introduce the future technical and social impact of open data on the open platform. Nowadays, web technology, whose process of standardization is open and independent of vendors, has evolved into an application platform on various devices such as PC, mobile and embedded devices. Developers of web-standards and web-based application are now trying to integrate a map technology tightly into the web standards for the future mobile web-based applications. As an organizer of a workshop aiming to discuss the future web-based map technology, I will introduce emerging technology and discussion in this area. At the workshop I held in Tokyo, Japan in 2012, many developers and researchers in various communities such as OpenStreetMap, FOSS4G, HTML5, and Linked OpenData gathered and had an enthusiastic discussion. I will summarize the discussion and future perspective at the workshop in my talk in order to discuss future technical and social possibility of OpenStreetMap on web-based open platform.

Open Data on the Open
Platform

2. Open Source Movement since late 90s
• Everyone can read the source code of software
• Everyone can participate to the development
• Open the know-how of enterprise, large-scale
software to engineers in every domain
• Broke the barrier between amateur and enterprise
technology
• Create a chance of technological communication
among engineers in different domains

3. Open Data Movement
• Chance to democratize
the knowledge of
government, large
company, specialists to
citizen
• Exchange the way of
finding knowledge
among

4. Open Platform Movement is Coming!
• Platform: a common mechanism on which an
application runs
• OS，Middleware, Web service, Distribution mechanism of apps
or content…
• Organization who control the platform would have great
benefit
• Microsoft, Google, Apple, Facebook ….
• Web technology (HTML5) is going to be the next
platform
• Vendor independent organization (W3C)
• Open discussion of specification

5. Proprietary Platform
• Software for the one platform does not run on
another platform

6. HTML5 as an Open Application Platform
• Web Browser is becoming to be
an Application Platform
• Create Application with HTML,
CSS and JavaScropt
• API Support for development
• Basement
• File API, Drag and Drop, Offline support
• Graphics and animation
• css3, canvas, SVG, WebGL. etc
• Device, Hardware
• Location, Accelerometer, etc

7. Little Support of Map/Geo-Features in HTML5
• No Standard Map Feature
• No standard API of rendering vector map
• No standard API of drag and drop map
• No standard API of expansion
• Difficult to create interactive mapping apps.
• Little Standard Geo-App Features Support
• Geo Location API
• Basic support to access to the GPS
• No standard API to measure the distance
• No standard API of geocoding / reverse geocoding
• No standard API of geo event
• Enter the area, stay more than 5 min etc..

8. Why Google ?
• Why you use google maps ?
• Because its content is wide coverage, rich info, accurate,
beautiful…
• OSM can be the alternative !
• Why you develop Geo/Map app with google maps
API ?
• Because it provides many useful features
• Simple API to embed a Map
• Measurement of the distance
• Geocoding ….
• There is no alternative !
• Need Open Geo / Mapping Platform!

14. MapStreet: Revolution in Tiled Map
• @_hfu_
• Introduced his vision and
prototype of the future web map
• Map data will be a commodity
• Platform to render and distribute
the tiled map will be a
commodity
• The quality of the presentation
( visualization cartography ) will
be the next competition
• Any map maker including
amature can participate the
competition
• Just like a street musician

15. Demo: tsukubau /MapBox
• Demonstrate his cartographical
idea
• Data:
• Fundamental Geospatial Data
• Geospatial Information Authority of
Japan
• Technology:
• TileMill for map tile generation
• MapBox for hosting in the cloud
