The <\/SPAN>terrace <\/SPAN>geomorphic feature layer represents the spatial extent of the <\/SPAN>terraces<\/SPAN> of the worlds oceans based on interpretation of the SRTM30 plus v7 global bathymetry model.

In this study terraces (broad steps) were calculated based on the gradient of the SRTM30_PLUS model. The SRTM30_PLUS model was masked using the slope feature layer (i.e. terraces we only mapped on the continental slope). <\/SPAN><\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "canModifyLayer": false, "supportedSpatialRelationships": [ "esriSpatialRelIntersects", "esriSpatialRelContains", "esriSpatialRelCrosses", "esriSpatialRelEnvelopeIntersects", "esriSpatialRelIndexIntersects", "esriSpatialRelOverlaps", "esriSpatialRelTouches", "esriSpatialRelWithin", "esriSpatialRelRelation" ], "geometryProperties": { "shapeAreaFieldName": "st_area(shape)", "shapeLengthFieldName": "st_length(shape)", "units": "esriMeters", "mapUnits": {"uwkid": 9001} }, "indexes": [ { "name": "r749_sde_rowid_uk", "isUnique": true, "description": "", "fields": "objectid", "isAscending": true }, { "name": "a578_ix1", "isUnique": true, "description": "", "fields": "shape", "isAscending": true } ], "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "supportsDatumTransformation": true, "minScale": 0, "supportsDynamicLegends": true, "hasAttachments": false, "advancedQueryCapabilities": { "supportsStatistics": true, "supportsSqlExpression": true, "supportsTrueCurve": true, "supportsOrderBy": true, "supportsQueryRelatedPagination": true, "supportsSqlFormat": false, "useStandardizedQueries": true, "supportsLod": false, "supportsQueryWithDistance": true, "supportsQueryWithDatumTransformation": true, "supportsCountDistinct": true, "supportsCurrentUserQueries": true, "supportsAdvancedQueryRelated": true, "supportsReturningQueryExtent": true, "supportsQueryWithLodSR": false, "supportsPagination": true, "supportsDistinct": true, "supportsTimeRelation": true, "supportsQueryAnalytic": true, "supportsPercentileStatistics": true, "supportsHavingClause": true }, "subtypeField": null, "serviceItemId": "ab9877e84b514604a5e20874622aa095", "supportsCoordinatesQuantization": true, "capabilities": "Map,Query,Data", "maxScale": 0, "supportsExceedsLimitStatistics": true, "defaultVisibility": true, "advancedQueryAnalyticCapabilities": { "supportsAsync": false, "supportsLinearRegression": true, "supportsPercentileAnalytic": false }, "hasMetadata": true, "typeIdField": null, "defaultSubtypeCode": null, "supportedQueryFormats": "JSON, geoJSON, PBF", "hasLabels": false, "drawingInfo": { "renderer": { "symbol": { "outline": { "color": [ 110, 110, 110, 255 ], "width": 0.69999999999999996, "style": "esriSLSSolid", "type": "esriSLS" }, "color": [ 196, 252, 238, 255 ], "style": "esriSFSSolid", "type": "esriSFS" }, "type": "simple" }, "scaleSymbols": true, "transparency": 0, "labelingInfo": null }, "geometryField": { "name": "shape", "alias": "shape", "type": "esriFieldTypeGeometry" }, "copyrightText": "The global seafloor geomorphic features map has been produced through a collaboration between Geoscience Australia, GRID-Arendal and Conservation International.\nReference: Harris et. al.
