1. A Use Case for GEON 1 A user request of the form: “For a given region (i.e. lat/long extent, plus depth), return a 3D structural model with accompanying physical parameters of density, seismic velocities, geochemistry, and geologic ages, using a cell size of 10km”

2. Data Access and Integration 2 D A T A Data Access Services Interactive data Integration and visualization Interactive data Integration and visualization Data transformations, processing EarthScope GEON OpenTopo USGS GIN … OpenEarth Framework Data transformations, processing

3. 3

4. e.g. OEF Viewer Data Discovery Data Discovery: –Federated metadata catalogs –Other sources of structured data

5. e.g. OEF Viewer Data Access Services Data Access Services: –Manage and deliver stored data and metadata –Provide access to data in a variety of formats via various sources. –Hide storage and access details (location, authentication, protocols etc.)

6. e.g. OEF Viewer Data Modeling Services Data Modeling Services: –Provide on-demand and preprocessing operation on requested data. –Operations to subset, extract and derive data for area of interest. –Use recent access patterns to guide preprocessing to prepare data in anticipation of future need.

7. e.g. OEF Viewer Interaction Services Data Integration Services: –Designed to support rapid visualization of integrated datasets –operations to grid data, resample it at multiple resolutions and subdivide data to better support progressive changes to the display as the user pans and zooms

8. e.g. OEF Viewer OEF Architecture Visualization Tools: –Run on the user's computer, dynamically query spatial and temporal data from the OEF services –Use 3D graphics hardware for fast display –Open architecture supports multiple visualization tools authored throughout the community (e.g GEON IDV) –New viz capabilities developed as necessary
