A Web Services Model for Geoscience Information Lee Allison - Arizona Geological Survey 3-D Geologic Mapping for Hydrogeology – GSA Short Course – October 27, 2007

A new paradigm for digital geoscience information

20 th century model Give us your data Individualized data centers Convert your formats, system, servers

Problems with the old model Loss of control of your data “Business model” not sustainable Stove-piped data sets

Data Structures Proprietary Software, Versions Operating Systems, Servers Users With thanks to Lesley Wyborn, GA

Federal and state geological surveys will create a national geoscience information system Distributed Distributed Interoperable Interoperable Modular, scalable Modular, scalable Service Oriented Architecture (SOA) Service Oriented Architecture (SOA) Geoscience Information Network USGS – State Geologists, February 2007

Interoperability The network is voluntary, not imposed from above

We won’t take your data away – it stays with you We won’t take your data away – it stays with you Your participation is voluntary Your participation is voluntary Keep your formats, system, servers Keep your formats, system, servers

Web services are abundant

“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.”

“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.”

With the Geospatial Instant Messenger, chat, find, download and retrieve geospatial data and web services from other Network participants.

Create, publish and share a geospatial workspace with other community members.

Switch worlds and view the geographic and location-based content in another user’s work space within the Network.

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.
