Outline

Exchanging geologic map information geologic map data interoperability via geospatial web services

Developing a standard GML data format IUGS development of XML data format standard (GeoSciML) and testbed

Objectives

Geologic map data schematic interoperability develop a standard GML schema for data transfer in WFS and WMS conduct a multi-country testbed, including schema translators demonstrate the need for transfer standards for data content

Activities: GeoSciML design

1. Kick-off meeting Nov. 2003, Edinburgh, U.K, at BGS 15 countries represented agree to share info. using OGC web services agree to be working group of IUGS-CGI Data Model Collaboration Working Group (DMC WG)

three task groups (TG) created for DMC WG

Data Interchange TG: develop GML schema

Testbed TG: test GML in WMS, WFS

Vocabulary TG: link with thesaurus WG

http://www.cgi-iugs.org/

Activities: GeoSciML design

2. Data Interchange Task Group Dec. 2004, Perth, AU, at CSIRO reviewed existing models

NADM C1, XMML, USGS, BGS, JGS, BRGM, AU,…

geological units, materials, structures, boreholes initiated 7 teams for new GML development results:

showed Testbed 1 at IAMG05 for WFS boreholes

Activities: GeoSciML design

3. Data Interchange Task Group Aug. 2005, Ottawa, ON, at GSC drafted GeoSciML beta specified Tesbed 2, sharing geologic maps results:

completed GeoSciML 1.0 in Jan. 06

initiated Testbed 2 in Fall, 05

Activities: GeoSciML design

4. Data Interchange Task Group April 2006, Orleans, FR, at BRGM drafted GeoSciML 1.1 progress on Tesbed 2 results:

GeoSciML 1.1 to be completed May 06

Testbed 2 to be completed Sept. 06

Activities: Testbed 2

Participants GSC (Canada), USGS-MRP (USA), USGS-NGMDB (USA), BGS (UK),

BRGM (FR), VGS (AU), GA (AU), SGS (SWE)

Use cases Use case 1: display map, query one feature and return attributes in GeoSciML

Use case 2: query several map features and return GeoSciML file for download

Use case 3: reclassify map features based on GeoSciML attributes

Status All: in progress

Canada, US: completed use case 1and 2

Activities: Testbed 2

Significant Outcomes

GeoSciML adopted as national standard Australia (federal and state geological surveys) EU: being submitted to INSPIRE (EU Spatial Data Infrastructure)

Future Activities

GeoSciML Workshop / Session:6. GeoSciML 1.1 and Testbed 2 September 2006, Liege, BE, IAMG06 public forum for GeoSciML 1.1 and Testbed 2 special session at IAMG06

GeoSciML Task Group meeting:

5. Testbed 2 meeting Sept 2006, Brussels, BE make progress on GeoSciML 2.0 review GeoSciML 1.1

GeoSciML from national map database of Canada

GeoSciML international collaboration for standard geologic map data format an application of international geospatial standards (ISO, OGC) derived from NADM, XMML, and others to be released as IUGS-CGI standard in 2006 multi-country testbed is in progress Canada and U.S. contributing to testbed
