  1. Best Practices: Integration of OpenTopography DEM data with UIUC Viewshed tool SDSC OT team

  2. Outline • OpenTopography • Overview • OT Architecture • Test Example • LiDAR Point Cloud Data Access and Processing • Viewshed Analysis • Integration Process • Security Service • Catalogue Service • Workflow Scenario

  3. OpenTopography Facility • NSF Facility funded via EAR IF and OCI • Increase the amount of science-oriented LiDAR available online • Enhanced web-based processing capabilities, with a focus on computationally intensive tasks (leveraging SDSC resources). • Community support: Software tools, tutorials, short courses, Workshops

  4. OT SOA Architecture OGC Catalogue Interface CSW Server Metadata Management Server

  5. Teton Conservation District, Wyoming Lidar

  6. User Interface to access data

  7. User Interface for the simulation

  8. Visualization for results

  9. Opal toolkit with CyberGIS Security APIs SDSC Invoke the Service with Token Opal Server (Web Service) UIUC CyberGIS Gateway Verify the Token Create the Token Token Based Identity Server UIUC

  10. Metadata Service for OT datasets • CyberGIS gateway enhances the capabilities to store, manage, and use metadata. • Applications use the metadata model and APIs to manage data resources. • OGC Standard Catalogue Service • Metadata model • Metadata schema : ISO 19139 • CSW (Catalogue Service for the Web) service APIs enable users to publish, browse, and search for the specific metadata using CSW protocol. • Support HTTP binding

  11. The Workflow Scenario OT Facility Opal Web Services Data Processing Service Metadata Service Count Service Data Access Service Outputs: points.las points.laz points.tar.gz Outputs: Output.min.grid, asc, geotiff Output.max.grid, asc, geotiff Output.mean.grid, asc, geotiff Output..den.grid, asc, geotiff Output.idw.grid, asc, geotiff dems.tar.gz 150Million ?
