This dataset provides eight feature classes. The base feature class is called BlockGroups_bg and isn't generalized. The weighted centroids feature class is called BlockGroups_bg_cent. The centroids are weighted by the U.S. Block Centroids population distribution. Use the weighted centroids in report aggregation and spatial overlay operations. The BlockGroups_bg and BlockGroups_bg_cent feature classes contain all the attributes. There are six generalized boundaries feature classes and called: BlockGroups_bg_gen2, BlockGroups_bg_gen3, BlockGroups_bg_gen4, BlockGroups_bg_gen5, BlockGroups_bg_gen6 and BlockGroups_bg_gen7. These generalized features classes are provided to be used in mapping applications where very detailed feature classes can slow down performance.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "units": "esriMeters", "maxViewsCount": 20, "syncEnabled": false, "tables": [], "hasVersionedData": false, "supportedAppendSourceFilterFormats": "featureService", "hasViews": false, "layerOverridesEnabled": true, "supportsRelationshipsResource": true, "layers": [ { "name": "Daytime_Pop_Density", "id": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon" } ], "GUIDFormat": "O", "spatialReference": { "latestWkid": 3857, "wkid": 102100 }, "fullExtent": { "ymin": 2817033.756000001, "xmin": -9755471.9984, "ymax": 3632874.8572999984, "xmax": -8909001.3619, "spatialReference": { "latestWkid": 3857, "wkid": 102100 } }, "enableZDefaults": true, "allowUpdateWithoutMValues": true, "isLocationTrackingService": false, "supportedExportFormats": "sqlite,filegdb,shapefile,csv,geojson", "capabilities": "Query", "supportsAppend": true, "supportsDisconnectedEditing": false, "supportsSyncModelNone": true, "supportedAppendFormats": "shapefile,featureCollection,featureService", "supportsReturnDeleteResults": true, "currentVersion": 11.3, "advancedEditingCapabilities": { "supportsAsyncApplyEdits": true, "supportsApplyEditsbyUploadID": true, "supportsReturnEditResults": true, "supportedApplyEditsUploadIDFormats": "JSON" }, "supportedQueryFormats": "JSON", "initialExtent": { "ymin": 3195960.794606148, "xmin": -9225057.566155568, "ymax": 3279410.8856967925, "xmax": -9100637.40621825, "spatialReference": { "latestWkid": 3857, "wkid": 102100 } }, "serviceDescription": "", "editorTrackingInfo": { "allowOthersToUpdate": true, "enableEditorTracking": false, "allowOthersToDelete": false, "allowOthersToQuery": true, "enableOwnershipAccessControl": false }, "hasSyncEnabledViews": false, "copyrightText": "Esri; U.S. Census Bureau", "zDefault": 0, "supportsLayerOverrides": true, "serviceItemId": "a87146616d054990ae4177d4d9e5d023" }
