Interoperability Work Group Brodaric, Outline Web mapping approaches Levels of data interoperability Demo
Interoperability Work Group Brodaric, Two Approaches to Web Geology Maps Atlas (Geologic Cartographic System): mosaic of geologic map images GIS (Geologic Information System): collection of geologic map data
Interoperability Work Group Brodaric, Option 1: web ATLAS purpose:communication content:picture, text, URL function:view only standard:data systems
Interoperability Work Group Brodaric, optional Option 2: web GIS purpose: science, policy content: map data function: view, query, symbolize, download standard: data systems, data structure, data content
Interoperability Work Group Brodaric, Levels of Map Data Interoperability systems syntax schematic semantic Map System 1 scientific systems syntax schematic semantic Map System 2 scientific Integrated Map Scientific Interpretation (Geologist) Data Content (Ontology) Data Structure (GeoSciML) Data Language (GML) Data Services (WMS, WFS, WCS) Atlas GIS
Interoperability Work Group Brodaric, from Systems Interoperability aligning data system interfaces (web services) but: heterogeneous structure, content, interpretation STANDARD DATA INTERFACES to different data systems e.g. open geospatial web services (OGC)
Interoperability Work Group Brodaric, GEOLOGIC AGEROCK TYPE but: heterogeneous data content, interpretation from Schematic Interoperability aligning heterogeneous data structures STANDARD SCHEMA for data transfer
Interoperability Work Group Brodaric, GEOLOGIC AGEROCK TYPE Volcanic from Semantic Interoperability aligning heterogeneous definitions for data content Era Eon Period Series STANDARD DEFINITIONS data content: rock types, time scale, … data schema, metadata but: heterogeneous interpretation at map borders
Interoperability Work Group Brodaric, from Scientific Interoperability aligning heterogeneous scientific interpretations but: done by geologists, not computers (… for now?) Differences in: geometry geohistory description classification
Interoperability Work Group Brodaric, Example of Schematic Interoperability GeoSciML Testbed 2 IUGS-CGI Interoperability Work Group (IWG) - Use open standards for system & syntax (WxS,GML) - Develop standard schema for data exchange (GeoSciML) - Demonstrate the need for semantic standards - Three use-cases: view & query, download, symbolize
Interoperability Work Group Brodaric, GML Client USGS schema BRGM schema GSC schema BGS schema SGU schema GA schema GeoSciML Australia Sweden UK France USA Canada WMS WFS WMS WFS WMS WFS WMS WFS WMS WFS WMS WFS Example of Schematic Interoperability GeoSciML Testbed 2 multiple viewers custom tools many databases (ESRI, Oracle,shp, …) local data control standard interface custom translator one output data format
Interoperability Work Group Brodaric, Use-case 1: view map & query one object
Interoperability Work Group Brodaric, Use-case 2: select objects and download
Interoperability Work Group Brodaric, Use-case 3: symbolize by rock type, age
Interoperability Work Group Brodaric, Some questions for 1G: Atlas or GIS or hybrid? Level of interoperability? Leverage GeoSciML Testbed 2? GeoSciML Testbed 2 demonstration on Friday!
