Title: A Web Services Model for Geoscience Information
1A Web Services Model for Geoscience Information
Lee Allison - Arizona Geological Survey
3-D Geologic Mapping for Hydrogeology GSA Short
Course October 27, 2007
2A new paradigm for digital geoscience information
320th century model
- Give us your data
- Individualized data centers
- Convert your formats, system, servers
4Problems with the old model
- Loss of control of your data
- Business model not sustainable
- Stove-piped data sets
5Proprietary Software, Versions
Operating Systems, Servers
Data Structures

6Geoscience 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)
7The network is voluntary, not imposed from above
Interoperability
8Don't panic!
- We wont take your data away it stays with you
- Your participation is voluntary
- Keep your formats, system, servers
9WWW operates on simple protocols
- http hypertext transfer protocol ( ftp, etc)
- html hypertext mark-up language
- url universal resource locator
- browser
10Geoscience 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
11Orbitz is a web service bringing information
seamlessly from dozens of web sites or data bases
12Rainlog.orga web service built on Google Earth
13National Geologic Map Database

20Web services are abundant
21The 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.
22The 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.
23With the Geospatial Instant Messenger, chat,
find, download and retrieve geospatial data and
web services from other Network participants.
24Create, publish and share a geospatial workspace
with other community members.
25Switch worlds and view the geographic and
location-based content in another users work
space within the Network.
26Network 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.
