The storm surge model used 1m of SLR and calculated the bottom friction resistance (Manning's n) and wind roughness (Z0) parameters from a predicted 2050 SLAMM landcover map, which showed how marshes are predicted to migrate inland in the study area due by 2050 based on the 1m of sea level rise by 2100 scenario. The image was created from the original storm surge model point file by isolating all points that had positive elevation (land areas) and values other than -99999 (no data) for storm surge height. Once the points for storm surge height for land areas were selected, the difference between the maximum storm surge height from the NAVD88 mean sea level (0ft) was subtracted from each point’s elevation value to calculate the height of the storm surge above the ground surface. The resulting values for overland storm surge height for were then averaged together using a spatial join to a vector polygon grid with a resolution of 300m, which was based on the maximum spacing between points in the original file for the study area. The vector grid was then converted to a raster image with the same resolution, which represented the maximum predicted storm surge height over land areas for the study area.\nMetadata<\/b><\/br>", "geometryType": null, "copyrightText": "The Nature Conservancy", "parentLayer": { "id": 139, "name": "Predicted Storm Surge from a Hurricane Ike like event with 1m SLR by 2100 " }, "subLayers": [], "minScale": 0, "maxScale": 0, "defaultVisibility": false, "extent": { "xmin": -1.0648619222033234E7, "ymin": 3345314.378357151, "xmax": -1.0464719222033234E7, "ymax": 3507014.378357151, "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 }
