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 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
