The Future of Geospatial Web: Web Portals or Mashups ? by Dr. Ming-Hsiang (Ming) Tsou Associate Professor The Department of Geography, San Diego State University, USA 2010 Annual AAG Meeting, Washington, D.C. Session 5520 Geospatial Web and related cartographic research

Future ???

1602 World Map by Matteo Ricci. The First Map in Chinese to Show the “Americas” Visited Library of Congress Washington D.C.

Matteo Ricci 利瑪竇 坤輿萬國全圖 created in America's Birth Certificate by a German cartographer Martin Waldseemüller, the first map to bear the name "America"

Everyone can read the 1507 America's Birth Certificate from their Desktops! (use JPEG 2000 compression) Access from Web viewers Or local viewer – where to find the viewer?

Can we read the “digital map” from this floppy disk today? Mapping Technology will change after … 20 years? 100 years? 500 years?

Present (What can we do today?)

Geospatial Web (the next generation of Internet, and World Wide Web) Enables Knowledge Sharing and Archive Geospatial cyberinfrastructure integrates high- performance computing resources, interoperable Web services, and sharable geographic knowledge to facilitate the advancement of geographic information science (GIScience) research, geospatial technology, and geographic education. (Zhang and Tsou, International Journal of Geographical Information Science, 2009) Grid computing Cloud computing Web portals

The Future of Geospatial Cyberinfrastructure client-sides: Web Portals + Mashups High speed Internet Data Services Collaboration Map Services Analysis Services High performance data centers + Grid visualization, and storage resources Cloud computing + Grid computing Server-sides: Cloud computing + Grid computing

Web Portal Technical Framework

Web Portals Example: SDS

Web Portals: Enable Web Service Chains. (linking data flows and functions) (One at a time)

Mashups (hybrid web services) (Combine all functions / services together at once) - Synergy Map Server -A Map Server-B Data Server-C Map Browsers Mash-up Maps Map Users Can add more contents to Mashup Maps (Volunteer Geographic Information – VGI) Show up all together (hybrid functions)

Mashup Example: MAPS (developed by Jung, Chin-Te)

ArcGIS Server Web Services MAPS Mashup Framework Combine Google Docs / Google Maps / ArcGIS Web Services

Google Docs

Baja-Eco-Info Mapping Tool (developed by Ick Hoi Kim)

Baja-Eco Mashup Framework

Water Quality: Google Map Marker GIS layers: ArcGIS Server Mapping Services

Spatial Query functions in Google Map and change backgrounds

Web Portals vs. Mashup Web portals: PRO: help us accomplish very complicated GIS tasks, spatial analysis, and data search/archiving/sharing. CON: difficult to implement, expensive.Mashups: PRO: help us to combine multiple information / services together, very flexible, and easy to create. CON: lack of cartographic design and major GIS analysis functions.

Future …. Co-Exist… Peace fully… Web Portals for governments, scientific communities.\ (Closer link to Grid computing – High performance) Mashup for small business, public outreach, media, personal use, and funs! (Closer link to Cloud computing – Google Docs, etc.) Or Web Portals + Mashups? = MashPortal (Mash potato?)
