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 !
