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
