Statewide coverage included photos taken in 1993 (Bristol, Barnstable, Nantucket and Dukes Counties), 1999 (Plymouth, northern and southern Worcester, and eastern Franklin, Hampshire and Hampden Counties), and 2000 (Essex, Middlesex, Suffolk, Norfolk, central Worcester, western Franklin, Hampshire and Hampden, and Berkshire Counties). Using stereo pairs under a mirror stereoscope, the approximate centers of pools were located. These points were digitized in a heads-up manner onto the MassGIS black and white digital orthophotosat a scale of approximately 1:12,000.", "geometryType": "esriGeometryPoint", "sourceSpatialReference": { "wkid": 26986, "latestWkid": 26986 }, "copyrightText": "MassGIS", "parentLayer": { "id": 41, "name": "NRC" }, "subLayers": [], "minScale": 0, "maxScale": 0, "drawingInfo": { "renderer": { "type": "simple", "symbol": { "type": "esriSMS", "style": "esriSMSCircle", "color": [ 255, 0, 197, 255 ], "size": 4, "angle": 0, "xoffset": 0, "yoffset": 0, "outline": { "color": [ 0, 0, 0, 255 ], "width": 1 } }, "label": "", "description": "" }, "transparency": 0, "labelingInfo": null }, "defaultVisibility": true, "extent": { "xmin": 675850.3848450909, "ymin": 2978780.7464948217, "xmax": 709182.2158190903, "ymax": 3008355.20375, "spatialReference": { "wkid": 102686, "latestWkid": 2249, "vcsWkid": 5703, "latestVcsWkid": 5703 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeAsHTMLText", "displayField": "town", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [ { "name": "objectid", "type": "esriFieldTypeOID", "alias": "OBJECTID", "domain": null }, { "name": "pvp_id", "type": "esriFieldTypeDouble", "alias": "PVP_ID", "domain": null }, { "name": "town_id", "type": "esriFieldTypeSmallInteger", "alias": "TOWN_ID", "domain": null }, { "name": "town", "type": "esriFieldTypeString", "alias": "TOWN", "length": 21, "domain": null }, { "name": "globalid", "type": "esriFieldTypeGlobalID", "alias": "GlobalID", "length": 38, "domain": null }, { "name": "shape", "type": "esriFieldTypeGeometry", "alias": "Shape", "domain": null } ], "geometryField": { "name": "shape", "type": "esriFieldTypeGeometry", "alias": "Shape" }, "indexes": [ { "name": "r569_sde_rowid_uk", "fields": "objectid", "isAscending": true, "isUnique": true, "description": "" }, { "name": "uuid_569", "fields": "globalid", "isAscending": true, "isUnique": false, "description": "" }, { "name": "uuid_oid_569", "fields": "globalid,objectid", "isAscending": true, "isUnique": true, "description": "" }, { "name": "a524_ix1", "fields": "shape", "isAscending": true, "isUnique": true, "description": "" } ], "subtypes": [], "relationships": [], "canModifyLayer": true, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query,Data", "maxRecordCount": 1000, "supportsStatistics": true, "supportsAdvancedQueries": true, "supportedQueryFormats": "JSON, geoJSON", "isDataVersioned": true, "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, "dateFieldsTimeReference": null, "supportsCoordinatesQuantization": true }
