1 National Geothermal Data System and Global Geosciences Data Integration Lee Allison, AZGS Stephen Richard, AZGS Arlene Anderson, US DOE David Cuyler, US DOE & Sandia Natl Lab NERC 2008

2 Outline Rational Approach Components and implementation

3 Geothermal community s #1 request: ready access to relevant data

4 how to turn this.

5 .into this NERC 2008

7 Data Integration Framework 1,000 s Distributed of databases 1,000 s of collections Web-based 80,000+ geologic maps Interoperable Open source Geoscience Information Network (GIN)

8 The Goal

9 a decade of advances in cyberinfrastructure and community practice Modular approach build a network by adopting and linking existing capabilities

10 Loose coupling between data provider and consumer KML GeoSciML WaterML

11 Shift the Burden from the User to the Provider Effort to create Web Services Dynamic pages on the fly from database Static HTML pages Effort to maintain Effort to get data More complex data management Peter Fox, RPI, 2010

12 Shift the Burden from the User to the Provider Server-side data integration standard interchange data schema Access to data from within user applications

13 USGIN System overview

14 The components Catalog find information Clients use information Services get information

15 Metadata profile The Catalog ISO 19115/119/139, USGIN profile Basic content requirements low hurdle Co development with Energistics Metadata Search service protocol OpenGeospatial Consortium Catalog Service for the Web (OGC CSW) Metadata repository Various open-source and commercial Using ESRI Geoportal

18 The Clients Software running on user s desktop System is not useful without these USGIN targeting existing clients ArcMap, Excel Goal is to promote client development with rich content offering

19 The Services Protocol Messaging framework and interface WFS, WMS, CSW Interchange format How is content encoded XML, JSON Server implementation GeoServer ESRI ArcGIS server

20 Protocol: WMS Simple, widely used, many clients Access to georeferenced map image Servers MapServer, GeoServer, Deegree, ArcGIS

21 WMS for well headers

22 Protocol - WFS Open Geospatial Consortium Web Feature Service GetCapabilities, GetFeature, DescribeFeature GML encoding of content Each service defines feature content model (xml schema)

23 WFS example

24 Protocol: ArcGIS services If using ArcGIS software clients, service is transparent Other clients are available

25 AASG State Geothermal data at ArcGIS.com

26 Interchange format XML Simple features Content models developed according to available information

27 Content Models

28 Summary Lots of work on discovery ISO metadata Carefully considered profile ESRI geoportal Use services that have out of the box clients and servers Keep content schema simple Use existing information as guide
