AIS are a navigation safety device that transmits and monitors the location and characteristics of many vessels in U.S. and international waters in real-time. The data represent vessel transit counts in 100 meter grid cells. A single transit is counted each time a vessel track passes through, starts, or stops within each grid cell.", "geometryType": "esriGeometryPolygon", "copyrightText": "Automatic Identification Systems, U.S. Coast Guard", "parentLayer": { "id": 42, "name": "Monthly Vessel Transit Counts" }, "subLayers": [], "minScale": 0, "maxScale": 0, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 201, 242, 208, 255 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 110, 110, 110, 255 ], "width": 0.4 } }, "label": "", "description": "" }, "transparency": 0, "labelingInfo": null }, "defaultVisibility": false, "extent": { "xmin": -8794269.7374, "ymin": 3895278.3932000026, "xmax": -7124369.737400001, "ymax": 5676078.393200003, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "timeInfo": { "startTimeField": "Date", "endTimeField": null, "trackIdField": null, "timeExtent": [ 1672531200000, 1701388800000 ], "timeReference": null, "timeInterval": 17, "timeIntervalUnits": "esriTimeUnitsDays", "exportOptions": { "useTime": true, "timeDataCumulative": false, "timeOffset": null, "timeOffsetUnits": null }, "hasLiveData": false }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "Name", "typeIdField": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "Shape", "type": "esriFieldTypeGeometry", "alias": "Shape", "domain": null }, { "name": "Raster", "type": "esriFieldTypeRaster", "alias": "Raster", "domain": null }, { "name": "Name", "type": "esriFieldTypeString", "alias": "Name", "length": 256, "domain": null }, { "name": "Date", "type": "esriFieldTypeString", "alias": "Date", "length": 255, "domain": null }, { "name": "Shape_Length", "type": "esriFieldTypeDouble", "alias": "Shape_Length", "domain": null }, { "name": "Shape_Area", "type": "esriFieldTypeDouble", "alias": "Shape_Area", "domain": null } ], "indexes": [ { "name": "FDO_OBJECTID", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "FDO_Shape", "fields": "Shape", "isAscending": true, "isUnique": false, "description": "" } ], "relationships": [], "canModifyLayer": false, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 1000, "supportsStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, AMF, geoJSON", "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsPagination": true, "supportsTrueCurve": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true } }
