Gauges in normal condition are left off the smallest scale maps, because this is not a map of gauges <i>per se<\/i>.&nbsp; This map is about high water. The subject of the map is current flooding and uses gauges to tell the story.<\/p>\n<p>If you would like a brief guided tour that will get you started<br \/>\nusing this map, Caitlin Scopel of the esri Mapping Center Team prepared<br \/>\nthis <a href=\"http:\/\/video.arcgis.com\/watch\/410\/esris-high-water-web-mapping-application\" title=\"Link to esri High Water Map tutorial video\" target=\"_blank\">five minute introductory video<\/a> which will show you how to get started using the High Water Map and how to get the most out of this resource.<\/p>\n<p>In case you are wondering where the gauge went that you know exists but <b><i>isn&#8217;t<\/i><\/b> on our map, you should know that our viewer is set up at this time to only parse xml feeds from the National Weather Service and NOAA.&nbsp; This is largely because it is the most well-represented gauge network in the United States.&nbsp; It is the one with the best coverage nationwide, but it is by no means the only system of gauges in the United States or the world.&nbsp; In the United States and many countries around the world, there is no single common live gauge reporting system. So to demonstrate the map we chose a reliable, authoritative gauge system which covers most of the major river systems in the United States.<\/p>\n<p>The High Water Map has the potential, however, to be adapted to read gauges from other agencies around the world with a few adaptations.<\/p>\n<p>At this point in time there is promise there will be in the future a common worldwide system of gauge reporting.&nbsp; A standard based upon <a href=\"http:\/\/his.cuahsi.org\/wofws.html\" title=\"WaterML\" target=\"_blank\">WaterML<\/a> holds promise for the creation of a global, live gauge data stream using a common publishing format.&nbsp; Once this standard is agreed upon and implemented, the public stands to greatly benefit.&nbsp; With a common standard and structure, all mapping technologies may combine, read and show live services.&nbsp; A common standard and structure lets every gauge be in every map now, in everything from simple products to sophisticated forecasting and analysis.<\/p>\n<p><i><b>Special thanks to Michael Dangermond for providing this post.<\/b><\/i> Questions for Michael: mdangermond@esri.com<\/p>\n"}],"authors":[{"ID":4911,"user_firstname":"Caitlin","user_lastname":"Scopel","nickname":"Caitlin Scopel","user_nicename":"coscopel","display_name":"Caitlin Scopel","user_email":"CScopel@esri.com","user_url":"","user_registered":"2018-03-02 00:16:31","user_description":"Senior Project Manager for the ArcGIS Living Atlas of the World Environment Team.
