The service supports site-scale monitoring of surface movement and deformation trends. <b>Overview</b> <p>This feature service provides InSAR-derived point observations and displacement records for the Keystone Dam area in Oklahoma. It supports analysis of surface movement and related deformation patterns using remotely sensed measurements.</p> <b>Feature Layers and Tables</b> <ul> <li><b>Keystone_Dam_InSAR_Points</b> — A point layer representing InSAR measurement locations associated with the Keystone Dam area. The layer includes spatial position, coherence and velocity-related attributes, and precision indicators that support interpretation of point stability and movement quality.</li> <li><b>KeystoneDamPS_displacements</b> — A table of displacement observations with date and displacement values tied to an identifier, supporting time-based review of movement trends.</li> </ul> <b>Geographic Coverage</b> <p>The data covers the Keystone Dam area in Oklahoma and is centered on a localized study region suitable for site-scale monitoring and assessment.</p> <b>Use Cases</b> <ul> <li>Monitoring ground or structure movement near Keystone Dam</li> <li>Reviewing InSAR point measurements and displacement trends over time</li> <li>Supporting deformation analysis, stability assessments, and engineering studies</li> <li>Integrating with GIS workflows for terrain and infrastructure change detection</li> </ul> -96.27311026513944 -96.22394389489287 36.16070874419126
