2
A new paradigm for digital geoscience information
3
20th century model

• Give us your data
• Individualized data centers
• Convert your formats, system, servers

4
Problems with the old model

• Loss of control of your data
• Business model not sustainable
• Stove-piped data sets

5
Proprietary Software, Versions
Operating Systems, Servers
Data Structures

Geoscience Information Network USGS State
Geologists, February 2007

• Federal and state geological surveys will create
  a national geoscience information system
• Distributed
• Interoperable
• Modular, scalable
• Service Oriented Architecture (SOA)

7
The network is voluntary, not imposed from above
Interoperability
8
Don't panic!

• We wont take your data away it stays with you
• Your participation is voluntary
• Keep your formats, system, servers

9
WWW operates on simple protocols

• http hypertext transfer protocol ( ftp, etc)
• html hypertext mark-up language
• url universal resource locator
• browser

10
Geoscience Information Network protocols

• Open source standards Open Geospatial
  Consortium
• Data interchange tool GeoSciML
• Distributed data catalogues National Geologic
  Map DB National Data Catalogue, etc
• Web services
• 4-D search tools

Orbitz is a web service bringing information
seamlessly from dozens of web sites or data bases

Web services are abundant
21
The Leica TITAN Network is a dynamic online
solution for sharing geospatial content in a
single, secure environment. Empowered by a 3D
virtual globe, the Leica TITAN Network allows
users to discover, visualize, share and retrieve
information.
22
The Leica TITAN client application is a free
web-based application that enables a global
network of users to interactively visualize and
share data for the purpose of contributing to
the creation of an online and information-rich 3D
virtual globe.
23
With the Geospatial Instant Messenger, chat,
find, download and retrieve geospatial data and
web services from other Network participants.
24
Create, publish and share a geospatial workspace
with other community members.
25
Switch worlds and view the geographic and
location-based content in another users work
space within the Network.
26
Network enables discovering, visualizing, sharing
and retrieving geospatial content (images,
terrain, 3D models, and vector data) and
location-based content like photos and live
camera feeds.
