In 2017, partnership with City of Kirkland, Mercer Island contracted with GeoTerra, Inc. to acquire a contigous block of leaf-off flight. On March 19th, clear skies accompanied with a reasonable window of high sun angle allowed for GeoTerra\u2019s first flight opportunity. Photography was acquired between 11:22am and 2:39pm (PDT) when sun angles were above 35 degrees from horizon. 3-band digital photos were acquired on March 19th using the Vexcel UltraCamFlacon Prime. Each digital image was processed from native format into final 8-bit, 3-band TIF files for use in aerial triangulation and ortho-image processing. A radiometric adjustment was applied on each image using UltraMap to remove the effects of sun spots, and a Project-Based .Color Balance for the blocks of imagery to produce a seamless color across the project areas. <\/SPAN><\/P><\/DIV><\/DIV>", "geometryType": null, "copyrightText": "GeoTerra, Inc. \nCity of Kirkland\nCity of Mercer Island", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "defaultVisibility": true, "extent": { "xmin": 1287000, "ymin": 192000, "xmax": 1305000, "ymax": 222000, "spatialReference": { "wkt2": "PROJCRS[\"NAD_1983_HARN_StatePlane_Washington_North_FIPS_4601_Feet\",BASEGEOGCRS[\"GCS_NAD83_WASHINGTON_OREGON_HPGN\",DATUM[\"D_North_American_1983_HARN\",ELLIPSOID[\"GRS_1980\",6378137.0,298.257222101,LENGTHUNIT[\"Meter\",1.0]]],PRIMEM[\"Greenwich\",0.0,ANGLEUNIT[\"Degree\",0.0174532925199433]],CS[ellipsoidal,2],ANGLEUNIT[\"Degree\",0.0174532925199433]],CONVERSION[\"Lambert_Conformal_Conic\",METHOD[\"Lambert_Conformal_Conic\"],PARAMETER[\"false_easting\",1640416.666666667,LENGTHUNIT[\"Foot_US\",0.3048006096012192]],PARAMETER[\"false_northing\",0.0,LENGTHUNIT[\"Foot_US\",0.3048006096012192]],PARAMETER[\"central_meridian\",-120.8333333333333,ANGLEUNIT[\"Degree\",0.0174532925199433]],PARAMETER[\"standard_parallel_1\",47.5,ANGLEUNIT[\"Degree\",0.0174532925199433]],PARAMETER[\"standard_parallel_2\",48.73333333333333,ANGLEUNIT[\"Degree\",0.0174532925199433]],PARAMETER[\"latitude_of_origin\",47.0,ANGLEUNIT[\"Degree\",0.0174532925199433]]],CS[Cartesian,2],AXIS[\"Easting (X)\",east,ORDER[1]],AXIS[\"Northing (Y)\",north,ORDER[2]],LENGTHUNIT[\"Foot_US\",0.3048006096012192]]", "wkt": "PROJCS[\"NAD_1983_HARN_StatePlane_Washington_North_FIPS_4601_Feet\",GEOGCS[\"GCS_NAD83_WASHINGTON_OREGON_HPGN\",DATUM[\"D_North_American_1983_HARN\",SPHEROID[\"GRS_1980\",6378137.0,298.257222101]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Lambert_Conformal_Conic\"],PARAMETER[\"false_easting\",1640416.666666667],PARAMETER[\"false_northing\",0.0],PARAMETER[\"central_meridian\",-120.8333333333333],PARAMETER[\"standard_parallel_1\",47.5],PARAMETER[\"standard_parallel_2\",48.73333333333333],PARAMETER[\"latitude_of_origin\",47.0],UNIT[\"Foot_US\",0.3048006096012192]]", "xyTolerance": 0.003280833333333333, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -117104300, "falseY": -99539600, "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": null, "geometryField": {}, "indexes": [], "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, "supportsAdvancedQueryRelated": true, "supportsQueryRelatedPagination": true, "supportsPagination": false, "supportsLod": false, "supportsQueryWithLodSR": false, "supportsTrueCurve": true, "supportsQueryWithDatumTransformation": true, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": false, "supportsTimeRelation": true, "supportsSqlFormat": false, "supportsQueryAnalytic": false, "supportsCurrentUserQueries": true }, "supportsDatumTransformation": true, "dateFieldsTimeReference": null, "preferredTimeReference": null, "datesInUnknownTimezone": false, "hasMetadata": true, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": true, "serviceItemId": "9632a5bba0464863ae6720c2df5a8390" } ], "tables": [] }
