{ "currentVersion": 10.81, "id": 1, "name": "St_Croix_2015.sid", "type": "Raster Layer", "description": "Ayres Associates provided St. Croix County, Wisconsin, with digital color orthoimagery services in 2015 as part of WROC. The aerial imagery was collected on April 14, 2015, using a Microsoft Vexcel UltraCam Eagle sensor mounted in a fixed-wing aircraft. Aerial imagery was collected to support 1.0 foot ground sample distance (GSD) orthoimagery to meet ASPRS Class II horizontal accuracy specifications at 1\u201d = 200' map scale. The horizontal accuracy meets or exceeds 4.0 feet RMSE using the National Standard for Spatial Data Accuracy (NSSDA) standards. Resultant orthoimagery was rectified to the new DEM from an existing LiDAR surface that was created as part of the CDBG funded WROC program. Orthoimagery was delivered in PLSS section GeoTiff and MrSID tiles and a project wide MrSID mosaic. The orthoimagery was delivered according to a four section tile schematic. The total project area is 736 square miles, plus a 500-ft buffer around the county boundary. Geographic Description: St. Croix County is located in western Wisconsin, at the edge of the Western Uplands region. The county has very few areas of urbanization and is characterized by steep sided valleys. The St. Croix Lake creates a natural border between Wisconsin and Minnesota, while the St. Croix and Namakogen Rivers miles of scenic exploration opportunites throughout the county. Supplemental Information: The Wisconsin Regional Orthophotography Consortium (WROC) is a multi-entity group led by regional planning commissions (RPCs) and WROC representatives from Ayres Associates. The goal of the consortium is to build and sustain a multi-participant program to acquire digital orthoimagery and elevation data throughout Wisconsin. Orthoimagery was collected for Crawford County in 2015 to provide consistent deliverable products and accuracy standards for each of the participating entities.", "geometryType": null, "copyrightText": "", "parentLayer": null, "subLayers": [], "minScale": 250000, "maxScale": 0, "defaultVisibility": true, "extent": { "xmin": -1.0331472375300812E7, "ymin": 5598495.986875489, "xmax": -1.0255579819152078E7, "ymax": 5655331.937193468, "spatialReference": { "wkid": 102100, "latestWkid": 3857 } }, "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, "supportsAdvancedQueries": false, "supportedQueryFormats": "JSON, geoJSON", "isDataVersioned": false, "ownershipBasedAccessControlForFeatures": {"allowOthersToQuery": true}, "useStandardizedQueries": true, "advancedQueryCapabilities": { "useStandardizedQueries": true, "supportsStatistics": false, "supportsHavingClause": false, "supportsCountDistinct": false, "supportsOrderBy": false, "supportsDistinct": false, "supportsPagination": false, "supportsTrueCurve": false, "supportsReturningQueryExtent": true, "supportsQueryWithDistance": true, "supportsSqlExpression": false }, "supportsCoordinatesQuantization": true }
