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

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

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

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 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
