Web Portals vs. MashupWeb Portals vs. MashupWeb portals: Web portals: • PRO: help us accomplish very complicated GIS
tasks, spatial analysis, and data search/archiving/sharing.
• CON: difficult to implement, expensive.
Mashups: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.

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.)

Web Portals + Mashups? = MashPortal (Mash potato?)
