Display Field: SURVEYDATE

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: <p><b>Overview</b></p><p>This feature service contains polygon features that represent bathymetric survey areas compiled by the U.S. Army Corps of Engineers for 2020. It provides a spatial record of surveyed channel or waterway areas and supports mapping, review, and analysis of bathymetric coverage.</p><p><b>Content</b></p><ul><li><strong>Polygon geometry</strong> representing mapped bathymetry survey extents.</li><li><strong>Survey metadata</strong> such as survey date, survey identifier, and mean depth.</li><li><strong>Area and shape measurements</strong> that help support spatial inspection and reporting.</li><li><strong>Created and edited tracking information</strong> for managing feature updates over time.</li></ul><p><b>Usefulness</b></p><p>The layer is well suited for bathymetric inventory, channel management, survey coverage review, and GIS workflows that document underwater terrain observations and related project records.</p>
