So What is Where 2.0? 15

Where 2.0 Conference • O’reilly Media • Every year / Over 800 participators • Sponsors MSN, AT&T, Outcast, Google, Yahoo, Akamai, sxip, AskJeeves, Fenwick&West, Laszlo, Morfik, SocialText, Newsgator • Main Theme Local Search and Advertising, Mobile, GeoIndex GeoTagged Life and DIY Data Platforms, Crowd Sourced Data and Realtime Data Open Source GeoStack Disaster Relief/Environment/NGOs: Sensorweb and Geotargeting • Technology Geo Support in Web Application Frameworks: Mapping APIs GeoBrowsers Protocols & Formats 17

Where 2.0? USGS, Landsat Base Map Google, Yahoo!, Microsoft ESRI, MapInfo SDK Softwares Web Maps APIs Topography, River, Layers Photo, Video, Tour Spots, Building Blog Outsourced digitizing Participators Web users vendors GML, WFS, WMS Standards GeoRSS, KML Government, local GIS 3rd Party Mashup developers vendors 18

Principals of 2.0 • How the Web Succeed? HTML Not Semantic Web (Machine-based Technology) • How the Geospatial Web? Google Maps Not ArcWeb (Proprietary-software Technology • How to make Geospatial Web to Web? Public Resources Easy Participation 19

Easy Participation of Alpha Users! 20

The Status of Where 2.0 • Data Visualization Google Earth, Yahoo Maps, MSN Virtual Earth, NASA World Wind • Social Data Social Location Mash-up • The Needs for Standards GML, KML, GeoRSS… • Movement of Desktop ESRI, GDAL, GLASS, UDIG • Location Sensing Plaze, Skyhook 21

Change: Conventional GIS Vendors • MapQuest The largest U.S based web map service provider OpenAPI Best service (2006) • ESRI The largest GIS vendors, Start-up to Web GIS. First sponsorship for Where 2.0 2006 • Skyline 3D Modeling Company. Patent issue with Google (Keyhole) • Autodesk Heading to Open Source (MapGuide Server) 22

Map APIs : pros and cons Pros Cons Google Map First Ajax based brilliant looking map Only Javascript libray International base map (Europe, Japan) Detail world-wide aerial photos Largest developer based APIs Lots of hacks and mash-up Yahoo! Map First external geocoding capability U.S. and Canada only Very flexible and open API's Flyouts not quite as spiffy as Google Rate limiting by IP instead of appID GeoRSS support Flash/Flex version available AOL MapQuest Frist routing (driving directions) capability No smooth Ajax client (yet) Geocoding capability Slow functional changes Large users and big market share Weak documentations Microsft Virtual Well documented and sample sites Low Performance Earth Detail Building shape and 3D view 24

Google Map API Code <script type=quot;text/javascriptquot; src=quot;http://www.google.com/jsapi?key=ABCDEFGquot;></script> <script type=quot;text/javascriptquot;> google.load(quot;mapsquot;, quot;2.xquot;); // Call this function when the page has been loaded function initialize() { var map = new google.maps.Map2(document.getElementById(quot;mapquot;)); map.setCenter(new google.maps.LatLng(37.4419, -122.1419), 13); } google.setOnLoadCallback(initialize); </script> 25

Mapping Mash-up? • Mashup Examples Chicagocrime http://www.chicagocrime.org World of Warcraft Map http://mapwow.com Themed Maps http://justin.everett-church.com/ymaps/radarMaps.html Flickr Maps http://www.sodascope.com/FlickrMapsExt MSNBC News Map http://poly9.viavirtualearth.com/Poly9/MSNBC 36

Google Maps + News Articles 37

Google Maps : My Map 38

What’s Open Standards? • Open Standard Data distribution with RESTful applications Ex) Google Maps, Flickr, Del.icio.us, Amazon, Ebay et. al Data exchage with XML specifications Ex) RSS/Atom, Microformat, Attention.xml • Basic of Open Standards Common APIs to geospatial data Easy to treat geospatial data from users to developers Various resources and library 40

What’s Open Source? • Success of Open Source Software Lightweight development framework for every developers Ex) LAMP (Linux+Apache+MySQL+PHP), Ruby on Rails, Python et. al Foundation for User-driven Innovation Ex) Firefox Extensions, RSS Aggregator, JSON et. al Various tools for developer-participation Ex) Wiki, Wordpress, Movable Type et.al • Basic of Open Source Software Voluntary developers participation Code-contribution by community 45

Open Source GIS • OSGeo.org Mapping Software and Map Data • NASA World Wind Open Source based 3D Geo Mapping S/W • Openstreetmap.org GPS based map data aggregation service. 46
