Example: Create maps and share via link GIS as (social) media
(Sui and Goodchild 2011)
Slide 3
Example: Create maps and share via a range of social media
outlets
Slide 4
Example: Create special interest groups, comment and rate
maps
Slide 5
Example: Add twitter feed to keep map users up to date
PGIST Challenge Monolithic web application Local client-server
architecture Technology specific Monolithic web application Local
client-server architecture Technology specific X Web Services? No,
much of the functionality is in the GUI. Need a Pluggable GUI
Framework that can support cross-domain and cross-platform
communication. Processing and persistence layers are hosted,
similar to SOA. Pluggable functionality Remote client-server
architecture Technology independent Pluggable functionality Remote
client-server architecture Technology independent How can the
CyberGIS Gateway be expanded to support collaborative problem
solving? VS.
