The service includes two feature layers and two related displacement tables that organize observation points and their time series measurements.</p><b>Feature Layers</b><ul><li><b>KeystoneDamPS</b> — Persistent scatterer points with velocity, coherence, precision, range, azimuth, location, and height-related attributes used to characterize radar-derived stability and motion.</li><li><b>KeystoneDamPS_Sentinel1</b> — A companion persistent scatterer layer built from Sentinel-1 observations with the same core movement and location attributes for analysis of surface deformation in the Keystone Dam area.</li></ul><b>Related Tables</b><ul><li><b>KeystoneDamPS_displacements</b> — Time-stamped displacement measurements linked to persistent scatterer features.</li><li><b>keystoneDamPS_Sentinel1_displacements</b> — Time-stamped displacement measurements linked to the Sentinel-1 persistent scatterer features.</li></ul><b>Geographic Coverage</b><p>The service covers the Keystone Dam area in northeastern Oklahoma and supports localized deformation monitoring for the surrounding infrastructure and terrain.</p><b>Use Cases</b><ul><li>Monitoring long-term surface deformation near dam infrastructure</li><li>Reviewing radar-based point stability and displacement trends</li><li>Supporting geotechnical assessment and infrastructure surveillance</li><li>Visualizing time series movement measurements in GIS applications</li></ul>Persistent scatterer radar analysis for the Keystone Dam area, including point features
