This dataset comprises polygons of census tracts for San Diego County. A census tract is a geographic region defined for the purpose of taking a census. Usually these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. In unincorporated areas, these are often arbitrary, except for coinciding with political lines. Census tracts are subdivided into block groups and census blocks.<\/SPAN><\/P>

The TIGER/Line Files are <\/SPAN>to tl_2020_06_tract.shp was downloaded from https://www.census.gov/cgi-bin/geo/shapefiles/index.php. Features intersecting San Diego County boundary were extracted and projected to NAD 83 State Plane. <\/SPAN><\/P>

The TIGER/Line Shapefiles are extracts of selected geographic and cartographic information from the Census Bureau's Master Address File (MAF)/topologically Integrated Geographic Encoding and Referencing (TIGER) Database (MTDB). <\/SPAN><\/P>

The TIGER/Line Shapefiles contain a standard geographic identifier (GEOID) for each entity that links to the GEOID in the data from censuses and surveys. <\/SPAN><\/P>

All Census Bureau generated shapefiles are in Global Coordinate System North American Datum of 1983 (GCS NAD83). <\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "syncCanReturnChanges": true, "supportsAsyncDelete": true, "supportedSpatialRelationships": [ "esriSpatialRelIntersects", "esriSpatialRelContains", "esriSpatialRelCrosses", "esriSpatialRelEnvelopeIntersects", "esriSpatialRelOverlaps", "esriSpatialRelTouches", "esriSpatialRelWithin" ], "geometryProperties": { "shapeAreaFieldName": "SHAPE__Area", "shapeLengthFieldName": "SHAPE__Length", "units": "esriFeet" }, "supportsRollbackOnFailureParameter": true, "isDataReplicaTracked": false, "standardMaxRecordCountNoGeometry": 16000, "indexes": [ { "name": "r3167_sde_rowid_uk", "isUnique": true, "description": "", "fields": "objectid_1", "isAscending": true }, { "name": "a2992_ix1", "isUnique": true, "description": "", "fields": "shape", "isAscending": true } ], "editFieldsInfo": null, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "minScale": 0, "hasAttachments": false, "advancedQueryCapabilities": { "supportsSqlExpression": true, "supportsQueryWithResultType": true, "supportsQueryWithCacheHint": false, "supportsQueryWithDatumTransformation": true, "supportsQueryAttachmentsWithReturnUrl": true, "supportsQueryDateBins": false, "supportsQueryWithLodSR": true, "supportsPaginationOnAggregatedQueries": true, "supportsPagination": true, "supportsMaxRecordCountFactor": true, "supportsStatistics": true, "supportsOrderBy": true, "supportsQueryWithDistance": true, "supportsLod": true, "supportsCountDistinct": true, "supportsQueryAttachments": true, "supportsReturningQueryExtent": true, "supportsQueryAttachmentsCountOnly": true, "supportsOrderByOnlyOnLayerFields": false, "supportsOutFieldSqlExpression": true, "supportsTopFeaturesQuery": true, "supportsDistinct": true, "supportsReturningGeometryCentroid": true, "supportsQueryAnalytic": true, "supportsPercentileStatistics": true, "supportsHavingClause": true }, "supportsValidateSQL": true, "enableZDefaults": true, "serviceItemId": "e0a2610f95a04f87aee4b921bd420d73", "allowUpdateWithoutMValues": true, "supportsCoordinatesQuantization": true, "types": [], "capabilities": "Query", "maxScale": 0, "supportsAppend": true, "supportsExceedsLimitStatistics": true, "defaultVisibility": true, "advancedQueryAnalyticCapabilities": { "supportsAsync": false, "supportsLinearRegression": true, "supportsPercentileAnalytic": false }, "hasMetadata": true, "supportedAppendFormats": "shapefile,geojson,csv,featureCollection,excel", "tileMaxRecordCount": 2000, "typeIdField": "", "supportsASyncCalculate": true, "supportedQueryFormats": "JSON, geoJSON, PBF", "sqlParserVersion": "PG_10.9.1", "drawingInfo": { "renderer": { "symbol": { "outline": { "color": [ 255, 235, 0, 255 ], "width": 1, "style": "esriSLSSolid", "type": "esriSLS" }, "color": [ 130, 130, 130, 0 ], "style": "esriSFSSolid", "type": "esriSFS" }, "type": "simple" }, "scaleSymbols": true, "transparency": 0, "labelingInfo": [ { "multiPart": "labelLargest", "symbol": { "backgroundColor": null, "kerning": true, "color": [ 0, 0, 0, 255 ], "yoffset": 0, "xoffset": 0, "haloColor": [ 255, 220, 0, 255 ], "type": "esriTS", "borderLineColor": null, "borderLineSize": null, "horizontalAlignment": "left", "haloSize": 1, "angle": 0, "rightToLeft": false, "verticalAlignment": "bottom", "font": { "size": 10, "weight": "bold", "style": "normal", "family": "Arial", "decoration": "none" } }, "stackLabel": true, "stackRowLength": 24, "maxScale": 0, "allowOverrun": true, "labelExpressionInfo": { "expression": "$feature.NAME", "title": "Custom" }, "deconflictionStrategy": "dynamic", "priority": -1, "labelPlacement": "esriServerPolygonPlacementAlwaysHorizontal", "removeDuplicates": "none", "name": "Class 1", "repeatLabel": false, "minScale": 0, "stackAlignment": "dynamic", "useCodedValues": true } ] }, "geometryField": { "modelName": "shape", "nullable": true, "editable": true, "defaultValue": null, "domain": null, "name": "shape", "alias": "Shape", "type": "esriFieldTypeGeometry" }, "copyrightText": "SANGIS using data provided by the United States Census Bureau (TIGER).", "zDefault": 0, "geometryType": "esriGeometryPolygon" } ] }
