Flow direction and Flow accumulation rasters were calculated to delineate flow paths. An accumulation threshold of 60 acres of upslope land was applied to identify a given pixel as a channel head; anything downstream of that channel head is identified as a flow path. The flow paths were then widened based on the total upslope area and the USGS regional curve equation for the Coastal Plain region of MD and VA. Large rivers and other open water features classified as \u201cwater\u201d in the high resolution land cover dataset were added to the widened flow paths dataset. This final integration is the \u201cenhanced flow path dataset.\u201d \nDownloadable from: https://chesapeakeconservancy.org/conservation-innovation-center/high-resolution-data/enhanced-flow-paths/pa-data-downloader/", "geometryType": null, "copyrightText": "Chesapeake Conservancy, Conservation Innovation Center, Chesapeake Bay Program, University of Vermont Spatial Analysis Laboratory", "parentLayer": null, "subLayers": [], "minScale": 0, "maxScale": 0, "defaultVisibility": true, "extent": { "xmin": -8549972.526789961, "ymin": 4820023.318727292, "xmax": -8442068.526789961, "ymax": 4923343.318727292, "spatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -20037700, "falseY": -30241100, "xyUnits": 1.4892314192838538E8, "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": false, "isDataArchived": false, "archivingInfo": { "supportsQueryWithHistoricMoment": false, "startArchivingMoment": -1 }, "supportsCoordinatesQuantization": true, "supportsDynamicLegends": true, "serviceItemId": "3d10df621bcc4b40b0f2c01b65745a68" }, { "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 1, "name": "Concentrated Flow/Accumulation ", "type": "Raster Layer", "description": "An intermediate raster in the enhanced flow path workflow (https://chesapeakeconservancy.org/wp-content/uploads/2018/07/CIC_Enhanced_Flowpath_Methods_20180703.pdf), flow accumulation represents the cumulative sum of all cells flowing into each downslope cell in the output raster.
