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

8. User Interface for the simulation

9. Visualization for results

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

11. 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
