So for example, an annexation document recorded in July 2013 would not be worked by the the Assessor for taxation purposes until 2014.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 2876, "latestWkid": 2876 }, "copyrightText": "Boulder County Assessor's Office GIS Department", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriSFS", "style": "esriSFSSolid", "color": [ 0, 0, 0, 0 ], "outline": { "type": "esriSLS", "style": "esriSLSSolid", "color": [ 0, 0, 0, 255 ], "width": 0.4 } }, "label": "", "description": "" }, "transparency": 0, "labelingInfo": null }, "defaultVisibility": true, "extent": { "xmin": 2966568.8968943357, "ymin": 1211481.6029126346, "xmax": 3124511.2080174237, "ymax": 1339077.1070314646, "spatialReference": { "wkid": 2876, "latestWkid": 2876 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "Authority_Name", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "OBJECTID", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "Authority_ID", "type": "esriFieldTypeInteger", "alias": "Authority_ID", "domain": null }, { "name": "Authority_Name", "type": "esriFieldTypeString", "alias": "Authority_Name", "length": 50, "domain": null }, { "name": "Notes", "type": "esriFieldTypeString", "alias": "Notes", "length": 150, "domain": null }, { "name": "Source", "type": "esriFieldTypeString", "alias": "Source", "length": 50, "domain": null }, { "name": "Source_Date", "type": "esriFieldTypeDate", "alias": "Source_Date", "length": 8, "domain": null }, { "name": "SHAPE", "type": "esriFieldTypeGeometry", "alias": "SHAPE", "domain": null }, { "name": "SHAPE.area", "type": "esriFieldTypeDouble", "alias": "SHAPE.area", "domain": null }, { "name": "SHAPE.len", "type": "esriFieldTypeDouble", "alias": "SHAPE.len", "domain": null } ], "geometryField": { "name": "SHAPE", "type": "esriFieldTypeGeometry", "alias": "SHAPE" }, "indexes": [ { "name": "R1361_SDE_ROWID_UK", "fields": "OBJECTID", "isAscending": true, "isUnique": true, "description": "" }, { "name": "a1146_ix1", "fields": "SHAPE", "isAscending": true, "isUnique": true, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": false, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 1000, "supportsStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, geoJSON", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": true, "supportsHavingClause": true, "supportsCountDistinct": true, "supportsOrderBy": true, "supportsDistinct": true, "supportsPagination": true, "supportsTrueCurve": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": true }, "supportsDatumTransformation": true, "hasGeometryProperties": true, "geometryProperties": { "shapeAreaFieldName": "SHAPE.area", "shapeLengthFieldName": "SHAPE.len", "units": "esriFeet" }, "dateFieldsTimeReference": null, "supportsCoordinatesQuantization": true } ], "tables": [] }
