Open Data on the Open Platform
@niyalist
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
Open Data Movement
• Chance to democratize the knowledge of government, large company, specialists to citizen
• Exchange the way of finding knowledge among
TED talk by Tim Berners-Lee in 2010 http://www.ted.com/talks/tim_berners_lee_ the_year_open_data_went_worldwide.html
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
Proprietary Platform
• Software for the one platform does not run on another platform
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
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..
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!
Geo + Web Workshop since 2010
• 1st: June, 2010 • 3 talks + 1 panel discussion (5 panelist) • 40 participants
• 2nd: March 11, 2011 “Mapping technology in the HTML5 Era” • 3 talks + 1 panel discussion (5 panelists) • →Could not hold due to the Great East Japan Earthquake
• 3rd: May, 2012 “Open Data on the Open Platform” • 5 talks • 60 more participants + 40 more online participants
• http://www.niya.net/gis/ • Slide, Video Twitter history is available ! (Japanese)
The 3rd Workshop Program
• MapStreet: Revolution in Tiled Map • @_hfu_
• HTML5 and beyond HTML5 • @wks・Masao Wakasa ( OSGeo Japan, Connecty
Inc.)
• Linked Data and Geospatial Data • @fumi1・Fumihiro Kato (National Institute of
Information)
• OpenStreetMap -provides free geographic data to anyone who wants it- • Taichi Furuhashi, Hal Seki, Tetsu Iida etc
• SVG Map: a Prototype of Web(Map|GIS) • @totipalmate・Satoru Takagi・(KDDI, W3C )
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
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
HTML5 and beyond HTML5
• @wks・Masao Wakasa • OSGeo Japan, Connecty Inc. • html5j.org
• Introduced the technical overview of HTML5 • Semantics • New Features and APIs • Introduced the advanced demonstration of html5
• Discussed the future of html5 web browser • Web Browser will be interface for anything • Car equipments • Home appliance etc…
Linked Data and Geospatial Data
• @fumi1・Fumihiro Kato • National Institute of Information • Researcher of Semantic Web /
Linked Open Data
• Introduced the basic idea and specification of Linked Data • Basic concept • Application • Problem
OpenStreetMap -provides free geographic data to anyone who wants it-
• Leading member of OSMJP • Taichi Furuhashi • Hal Seki • Tetsu Iida …
• Q&A session about OSM • Who start the project ? • Who is operating the server ? • What is the licese of the OSM data. • Who guarantee the accuracy ? • How to edit the map ? • How to download the data ? • What is the difference between shape file ? • Are there any application which highly utilize the OSM ?
SVG Map: a Prototype of Web(Map|GIS)
• @totipalmate Satoru Takagi • KDDI Corporation • W3C • Pioneer of web mapping technology since 90s • Far before Google Maps
• Propose the extension of SVG for presentation of Web map • Tiling, Layering
• We have his presentation today! 16:30〜 in this room. • “New mapping standards for the web”
What’s the Next ?
• Making a community of developers who have interest in this field • In Japan • World wide !
• Start to propose to W3C
• Need to create the new movement Open Data on the Open Platform for the interoperability of our knowledge !
