{ "currentVersion": 10.81, "cimVersion": "2.6.0", "id": 11, "name": "Nodes", "type": "Feature Layer", "description": "Location and attributes of points used to define the topology of the hydrologic network.\n\nThe S_Nodes layer is used for hydrologic analyses where nodes were defined as part of the analysis. The contributing drainage area and the discharges for all frequencies required for the flood risk project (e.g. the 10-percent, 2-percent, 1-percent, and 0.2-percent-annual-chance floods) represent the discharges based on the cumulative upstream drainage area. The points or nodes usually lie on the profile baseline, which reside in S_Profil_Basln, or the hydro reach line which resides in S_Hydro_Reach. Nodes can represent sub basin outlets, junctions, reservoirs, structures, or diversions. Note that nodes are required at all flow change locations. This information is used in the following tables in the FIS report: Summary of Discharges, Summary of Summary of Non-Coastal Stillwater Elevations, and Flood Hazard and Non-Encroachment Data for Selected Streams. For hydraulic models that use nodes, such as SWMM or ICPR, the nodes can be used to represent structures or hydraulic elements. In these cases, the nodes and the profile baseline layer are used to represent the hydraulic connectivity of the network. Nodes can also represent more detailed inventory, such as manholes or curb inlets.", "geometryType": "esriGeometryPoint", "sourceSpatialReference": { "wkid": 4269, "latestWkid": 4269, "xyTolerance": 8.98315284119521E-9, "zTolerance": 2.0E-5, "mTolerance": 2, "falseX": -400, "falseY": -400, "xyUnits": 7.6354937453853E8, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "", "parentLayer": null, "subLayers": [], "minScale": 36111.909643, "maxScale": 0, "referenceScale": 0.0, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriPMS", "url": "eac869c7cc4bee400adc3ca86404bc40", "imageData": "iVBORw0KGgoAAAANSUhEUgAAAAwAAAAMCAYAAABWdVznAAAACXBIWXMAAA7EAAAOxAGVKw4bAAABIElEQVQokZWRMUvDcBDF3wt/a0NTNQriLm4OgoujguJaEJwKihRxqIP6CaQ4OBVcBOvipJ1EhE6Cg4OVLupXyOLQJYqa2pDnoC1Go+APDo7jfnDcM/gnJmkoaQiAA8AjGf0qSBqTdPAaPU0bpGCYepC0QfLkhyBpuBl6N3uPBfe2dQHDHszZKyOFbPlYUi/Jo5gQRdF22V9y798uAQBttVB72YdjDSLvlMqSqiSDruBHzZnO8leugiryTskFMAGg3hWMZdoEIejbV1Kdth07KYOB86l0bvw6OI0Js/YyAHgA7mKCZVk7xf7KomO5o/XgDGlmMG+vIpfZDEkWSIYxgeSzpMlitrK73ne4gI8cGiS3SDYScyDpA1j7rEQSk/6Ld3meYOjHVSPxAAAAAElFTkSuQmCC", "contentType": "image/png", "width": 9, "height": 9, "angle": 0, "xoffset": 0, "yoffset": 0 } }, "scaleSymbols": true, "transparency": 0, "labelingInfo": null }, "defaultVisibility": false, "extent": { "xmin": -159.6655269033425, "ymin": 21.904090397161383, "xmax": -66.98810786443903, "ymax": 64.84163586737333, "spatialReference": { "wkid": 4269, "latestWkid": 4269, "xyTolerance": 8.983152841195213E-9, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -400, "falseY": -400, "xyUnits": 9.999999999999999E8, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "DFIRM_ID", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "DFIRM_ID", "type": "esriFieldTypeString", "alias": "DFIRM_ID", "length": 6, "domain": null }, { "name": "VERSION_ID", "type": "esriFieldTypeString", "alias": "VERSION_ID", "length": 11, "domain": null }, { "name": "NODE_ID", "type": "esriFieldTypeString", "alias": "NODE_ID", "length": 32, "domain": null }, { "name": "NODE_TYP", "type": "esriFieldTypeString", "alias": "NODE_TYP", "length": 16, "domain": null }, { "name": "WTR_NM", "type": "esriFieldTypeString", "alias": "WTR_NM", "length": 100, "domain": null }, { "name": "NODE_DESC", "type": "esriFieldTypeString", "alias": "NODE_DESC", "length": 100, "domain": null }, { "name": "MODEL_ID", "type": "esriFieldTypeString", "alias": "MODEL_ID", "length": 107, "domain": null }, { "name": "SOURCE_CIT", "type": "esriFieldTypeString", "alias": "SOURCE_CIT", "length": 21, "domain": null }, { "name": "GFID", "type": "esriFieldTypeString", "alias": "GFID", "length": 36, "domain": null }, { "name": "SHAPE", "type": "esriFieldTypeGeometry", "alias": "SHAPE", "domain": null }, { "name": "GlobalID", "type": "esriFieldTypeGlobalID", "alias": "GlobalID", "length": 38, "domain": null } ], "geometryField": { "name": "SHAPE", "type": "esriFieldTypeGeometry", "alias": "SHAPE" }, "indexes": [ { "name": "R111_pk", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "UUID_111", "fields": "GlobalID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "DFIRM_ID_OBJECTID", "fields": "DFIRM_ID,OBJECTID", "isAscending": true, "isUnique": false, "description": "" }, { "name": "S60_idx", "fields": "SHAPE", "isAscending": true, "isUnique": true, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": true, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 2000, "supportsStatistics": true, "supportsExceedsLimitStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, geoJSON, PBF", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsPercentileStatistics": true, "supportsHavingClause": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsCountDistinct": true, "supportsPagination": true, "supportsTrueCurve": true, "supportsQueryWithDatumTransformation": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": true }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "hasMetadata": true, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": true }
