Product: This orthoimagery data set includes 0.25 foot digital orthoimages in 8-bit 4-band (RGB-IR) GeoTIFF tiles and 8-bit 4-band (RGB-IR) MrSID mosaics (20:1 compression ratio). Geographic Extent: 3 counties in Massachusetts, covering approximately 13 total square miles. Dataset Description: The Cambridge, MA Orthoimagery project called for the planning, acquisition, processing, and derivative products of imagery data to be collected at a ground sample distance (GSD) of 0.25 foot. Project specifications are based on the American Society of Photogrammetry and Remote Sensing (ASPRS) standards. The data were developed based on a horizontal projection/datum of NAD 1983 2011 StatePlane Massachusetts Mnld FIPS 2001 FtUS, Foot US. Imagery data were delivered as 0.25 foot 8-bit 4-band (RGB-IR) GeoTIFF tiles and 8-bit 4-band (RGB-IR) MrSID mosaics (20:1 compression ratio). Tiled deliverables contained 53 individual 2640 ft x 2640 ft tiles. Ground Conditions: Imagery was collected in spring 2021, while no snow was on the ground and rivers were at or below normal levels.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "geometryType": null, "copyrightText": "NV5 Geospatial, powered by Quantum Spatial", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "defaultVisibility": true, "extent": { "xmin": 747000.049027401, "ymin": 2951879.9730515755, "xmax": 776040.049027401, "ymax": 2972999.9730515755, "spatialReference": { "wkid": 102686, "latestWkid": 2249, "xyTolerance": 0.003280833333333333, "zTolerance": 2.0E-4, "mTolerance": 2.0E-4, "falseX": -119851500, "falseY": -94498200, "xyUnits": 3048.0060960121928, "falseZ": -100000, "zUnits": 10000, "falseM": -100000, "mUnits": 10000 } }, "hasAttachments": false, "htmlPopupType": "esriServerHTMLPopupTypeNone", "displayField": "", "typeIdField": null, "subtypeFieldName": null, "subtypeField": null, "defaultSubtypeCode": null, "fields": [], "geometryField": {}, "indexes": null, "subtypes": [], "relationships": [], "canModifyLayer": false, "canScaleSymbols": false, "hasLabels": false, "capabilities": "Map,Query", "supportsStatistics": false, "supportsExceedsLimitStatistics": false, "supportsAdvancedQueries": false, "supportedQueryFormats": "JSON, geoJSON, PBF", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": false, "supportsPercentileStatistics": false, "supportsHavingClause": false, "supportsOrderBy": false, "supportsDistinct": false, "supportsCountDistinct": false, "supportsPagination": false, "supportsLod": false, "supportsQueryWithLodSR": false, "supportsTrueCurve": true, "supportsQueryWithDatumTransformation": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": false, "supportsTimeRelation": true, "supportsSqlFormat": false, "supportsQueryAnalytic": false }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "preferredTimeReference": null, "datesInUnknownTimezone": false, "hasMetadata": true, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": true } ], "tables": [] }
