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 1602
1507 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 highperformance 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
Endorsement by the Father of the
World Wide Web, Tim Berners-Lee

The Future of Geospatial Cyberinfrastructure
Server-sides: Cloud computing + Grid computing
High performance data centers + Grid
visualization, and storage resources
Map Services
Data Services
Analysis Services
High speed Internet
client-sides:
Web Portals + Mashups
Collaboration
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 Browsers
Map Server-B
Mash-up Maps
Data Server-C
Show up all together
(hybrid functions)
Map Users
Can add more contents to
Mashup Maps
(Volunteer Geographic
Information – VGI)
Mashup Example: MAPS
http://geoinfo.sdsu.edu/maps/
(developed by Jung, Chin-Te)
MAPS Mashup Framework
Combine Google Docs / Google Maps /
ArcGIS Web Services
ArcGIS Server Web Services
Google Docs
Baja-Eco-Info Mapping Tool
HTTP://geoinfo.sdsu.edu/baja
(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?)
