{ "currentVersion": 10.81, "serviceDescription": "Gulf of Mexico Depth Contours derived from NOAA's NGDC bathymetric grids and from BOEM's seismic grid compilation. Both NOAA and BOEM contours are shown in meters or feet depending on the user's preference. Contours were created to compare and contrast the older NOAA NGDC grid to the newer BOEM gridded bathymetry described below:\nBOEM's deepwater Gulf of Mexico bathymetry grid. Created by mosaicing over 100 3D seismic surveys. XY grid size is 40ft and depth is in feet. Depth accurate to 0.1% (one-tenth of one-percent) of water depth in most places. Depth accuracy decreases slightly when approaching minimum (-200ft) and maximum (-11,000ft) depth extents due to the nature of the depth transformation method used. BOEM thanks the following companies for allowing BOEM use of their data to create this new map: CGG Services (U.S.) Inc., Houston, TX; Exxon; Geophysical Pursuit; PGS; Seitel; TGS; and WesternGeco", "mapName": "Layers", "description": "", "copyrightText": "BOEM/BSEE", "supportsDynamicLayers": true, "layers": [ { "id": 0, "name": "OCS Drilling Platforms", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 9244648, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPoint" }, { "id": 1, "name": "OCS Oil and Natural Gas Wells", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 9244649, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPoint" }, { "id": 2, "name": "BOEM Limit of OCSLA 8(g) zone", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolyline" }, { "id": 3, "name": "Submerged Lands Act Boundary", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolyline" }, { "id": 4, "name": "BOEM OCS Protraction Diagrams & Leasing Maps", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon" }, { "id": 5, "name": "BOEM OCS Lease Blocks", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 18489297, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon" }, { "id": 6, "name": "BOEM Oil and Gas Leases", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 18489297, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon" }, { "id": 7, "name": "BOEM Oil and Gas Planning Areas", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 0, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPolygon" }, { "id": 8, "name": "BOEM Oil and Gas Lease Points", "parentLayerId": -1, "defaultVisibility": true, "subLayerIds": null, "minScale": 18489297, "maxScale": 0, "type": "Feature Layer", "geometryType": "esriGeometryPoint" } ], "tables": [], "spatialReference": { "wkid": 4269, "latestWkid": 4269 }, "singleFusedMapCache": false, "initialExtent": { "xmin": -455.68470569741163, "ymin": -185.7202371960039, "xmax": 455.68470569741163, "ymax": 573.7542722996823, "spatialReference": { "wkid": 4269, "latestWkid": 4269 } }, "fullExtent": { "xmin": -180, "ymin": 32.434614000037, "xmax": 180, "ymax": 74.99639892578129, "spatialReference": { "wkid": 4269, "latestWkid": 4269 } }, "minScale": 0, "maxScale": 0, "units": "esriDecimalDegrees", "supportedImageFormatTypes": "PNG32,PNG24,PNG,JPG,DIB,TIFF,EMF,PS,PDF,GIF,SVG,SVGZ,BMP", "documentInfo": { "Title": "BOEMRE Layers", "Author": "", "Comments": "", "Subject": "", "Category": "", "AntialiasingMode": "None", "TextAntialiasingMode": "Force", "Keywords": "BOEM" }, "capabilities": "Map,Query,Data", "supportedQueryFormats": "JSON, geoJSON", "exportTilesAllowed": false, "referenceScale": 0, "datumTransformations": [ { "geoTransforms": [ { "wkid": 108001, "latestWkid": 1241, "transformForward": true, "name": "NAD_1927_To_NAD_1983_NADCON" } ] }, { "geoTransforms": [ { "wkid": 108001, "latestWkid": 1241, "transformForward": false, "name": "NAD_1927_To_NAD_1983_NADCON" } ] } ], "supportsDatumTransformation": true, "maxRecordCount": 10000, "maxImageHeight": 2048, "maxImageWidth": 2048, "supportedExtensions": "KmlServer, WMSServer", "resampling": false }
