Software Upgrade and Modifications Made to Map Viewer and Map Services
 

On Tuesday, June 5th, 2012, the servers hosting nowCOAST were replaced and its map server software was upgraded from ArcIMS 9.2 to ArcIMS 10.0.

Due to differences between versions 9.2 and 10.0 of ArcIMS, users of nowCOAST's Web Map Services (WMS) are no longer able to request maps using the "EPSG:900913" projection identifier. All users currently requesting images with this identifier are advised to modify their clients as soon as possible to instead use one of the replacement identifiers supported by ESRI, such as "EPSG:3857" or "EPSG:102113". These identifiers represent the same web mercator projection as the one being replaced, so there should be no further changes required.

Additionally, output from the the NOS Experimental Gulf of Mexico Model (NGOM) was removed from both the nowCOAST map viewer and its 'guidance' Web Map Service (WMS). The NGOM system was decommissioned on April 13, 2012, and thus is no longer producing forecast guidance. Please be aware that any requests made to nowCOAST's 'guidance' WMS for any NGOM layers will now produce an error message.

For more information, please contact the nowCOAST team at: nowcoast.team@noaa.gov

Upcoming Maintenance
 

On Tuesday, June 5th, 2012, nowCOAST will be unavailable for approximately two hours, from 10:00am - 12:00pm, due to scheduled system maintenance. During the maintenance window, the servers hosting nowCOAST will be replaced and its map server software will be upgraded from ArcIMS 9.2 to ArcIMS 10.0.

Due to differences between versions 9.2 and 10.0 of ArcIMS, users of nowCOAST's Web Map Services (WMS) will no longer be able to request maps using the "EPSG:900913" projection identifier. All users currently requesting images with this identifier are advised to modify their clients as soon as possible to instead use one of the replacement identifiers supported by ESRI, such as "EPSG:102113" or "EPSG:3857". These identifiers represent the same web mercator projection as the one being replaced, so there should be no further changes required.

Additionally, during the maintenance, output from the the NOS Experimental Gulf of Mexico Model (NGOM) will be removed from both the nowCOAST map viewer and its 'guidance' Web Map Service (WMS). The NGOM system was decommissioned on April 13, 2012, and thus is no longer producing forecast guidance. Please be aware that any requests made to nowCOAST's 'guidance' WMS for any NGOM layers will no longer work after Tuesday, June 5th, 2012.

Problems with "Surface Water Currents" layers:
 
  Since October 26, 2011, there have been intermittent outages in the display of U.S. Navy Coastal Ocean Model (NCOM) forecast guidance layers on nowCOAST (normally avialable by selecting "Surface Water Currents" -> "Ocean Basins" in nowCOAST's map layer list). The outages have been caused by problems in the transmission of model output from the Navy to NWS/NCEP. Until the problem is fixed by the data providers, the intermittent outages will continue. Please contact nowcoast.team@noaa.gov with any questions or concerns.

nowCOAST Version 4.9 Released
 
Changes in nowCOAST Version 4.9:
 
  1) "Model Nowcast/Forecast Guidance: Surface Water Currents - w/Speed, w/Sea Surface Temp, w/Water Levels" map layers updated
     -> The new version of nowCOAST includes the latest nowcasts and forecast guidance from NOS operational oceanographic forecast modeling systems for the five Great Lakes, New York Harbor, St. John's River (FL), and Chesapeake, Delaware, Tampa and Galveston Bays. In addition, nowcasts and forecast guidance from the experimental NOS Gulf of Mexico Model (NGOM), as well as the Navy's Coastal Ocean Model (NCOM) are displayed. The surface water currents are displayed using flow visualization software developed by the Data Visualization Research Laboratory at the NOAA-UNH Joint Hydrographic Center/Center for Coastal and Ocean Mapping. The flow visualization technique overlays streaklets, which vary in size and direction with the velocity of the water currents, on top of color-coded backgrounds representing the magnitude of flow speed, sea surface temperature, or water level. For the water level graphics, a hillshade technique is also applied to the background color to emphasize the topography of the water surface.

     The forecast guidance from NOS estuarine and great lakes forecast systems are displayed at 6 hour intervals out to 24, 36 or 48 hours, depending on the forecast system, and is updated on nowCOAST four times per day after the completion of each update cycle which runs at 0, 6, 12, and 18 UTC. The updated guidance is available on nowCOAST by approximately 3 hours after each cycle's initialization time.

     Forecast guidance from the experimental NOS Gulf of Mexico Model (NGOM) is displayed at 12 hour intervals out to 72 hours, and is updated on nowCOAST twice per day after the completion of the 0 and 12 UTC forecast cycles.

     Forecast guidance from the Navy's Coastal Ocean Model (NCOM) is displayed at 12 hour intervals out to 48 hours, and is updated on nowCOAST once per day by approximately 18:30 UTC (2:30pm EDT). Occasionally, there are problems with the delivery of model output from the Navy to the National Weather Service, in which case NCOM graphics will not be displayed on nowCOAST until the following day.
 
  2) "Geo-Referenced Links: Surface Forecasts - Coastal and Offshore" map layer updated
     -> Updated coastal and offshore marine zone boundaries to the match latest revisions from NWS.

nowCOAST Version 4.8 Released
 
Changes in nowCOAST Version 4.8:
 
   1) "Forecasts - Gridded: Nat'l Digital Forecast Database - Surface Wind Gust" map layers added
     -> The new version of NOAA/NOS' nowCOAST provides on-map display of the latest Surface Wind Gust forecasts from the NWS National Digital Forecast Database (NDFD) valid at 6-hour intervals out to two days for CONUS, Hawaii, Alaska, and Puerto Rico. The surface wind gust forecast is the 3-second wind expected to occur within a 2-minute interval at a height of 10m (~30ft) above ground level, valid at the top of the specified hour. The NDFD surface weather forecasts have a horizontal resolution of 5km (3 miles) and are updated four times per day on nowCOAST: at 0000, 0600, 1200, and 1800 UTC. The Surface Wind Gust forecasts can be found on the nowCOAST map viewer under "Forecasts - Gridded (5km Resolution) - Nat'l Digital Forecast Database". The forecasts are also available via nowCOAST's 'forecasts' Web Map Service (WMS) and ArcIMS Image Service.
 
   2) NOAA/NOS Marine Transport Caution Area map layer added
     -> The new version also displays the latest Marine Transport Caution Area from the National Ocean Service's Office of Coast Survey. This layer depicts an area in the Gulf of Mexico inside which oil may be present and where the USCG highly encourages mariners to avoid. The Caution Area is updated three times per week on Monday, Wednesday and Friday based on the latest surface oil spill trajectory forecast from NOS' Office of Response and Restoration.

nowCOAST Version 4.7 Released
 
Changes in nowCOAST Version 4.7:
 
   1) Nowcast from Experimental NOS Gulf of Mexico Model (NGOM) Added
     -> The new version of nowCOAST provides on-map display of the latest nowcasts of surface water currents along with water level and surface water temperatures for the Gulf of Mexico from NOAA/National Ocean Service's experimental Gulf of Mexico Ocean Model (NGOM). NGOM is a limited-area, numerical oceanographic circulation forecast modeling system operated by NOS' Coast Survey Development Laboratory in Silver Spring, MD. Nowcasts from the experimental NGOM are valid at approximately 0000 (7PM CDT) and 1200 UTC (7AM CDT) and are available on nowCOAST by approximately 3:20 AM CDT and 7:00 PM CDT, respectively. The nowcasts can be found on the nowCOAST map viewer under 'Analyses/Nowcasts'. The nowcasts are also available via nowCOAST's guidance Web Map Service (WMS) and ArcIMS Image Service. The nowcasts are depicted using custom flow visualization software developed by the Data Visualization Research Lab at the University of New Hampshire's Center for Coastal and Ocean Mapping.

    Additional information about NGOM can be found by clicking on the corresponding "Gulf of Mexico (NGOM)" entry in the nowCOAST Table of Contents.

    Information on how to access the experimental NGOM nowcasts via nowCOAST's "guidance" Web Map Service can be found at:
http://nowcoast.noaa.gov/help/mapservices.shtml?name=mapservices#guidance
 
   2) "Geo-Referenced Links: Surface Forecasts - Coastal and Offshore" map layer updated
     -> Layer was updated to reflect changes to Coastal Marine Zone boundaries for the marine zones in the National Weather Service's New Orleans/Baton Roughe WFO (LIX) County Warning Area.
 




June 10, 2010
  1) "Geo-Referenced Links: Surface Forecasts - Terminal Aerodrome Weather (TAF)" map layer
     -> Updated geo-referenced hyperlinks to Terminal Aerodrome weather forecasts to include new TAF sites across the country including two new forecast locations established in the Gulf of Mexico region by NOAA's National Weather Service (NWS) to support the Deepwater Horizon oil spill response. The two sites are Stennis International Airport (KHSA) in Bay St. Louis, Mississippi, and Houma-Terrebonne Airport (KHUM) in Houma, Louisiana. The TAFs are needed for flight safety for the aviation assets being used in support of the oil spill recovery, restoration, and reclamation efforts.
 
  2) "Map Background: Coastal Watch/Warning Breakpoints" map layer
     -> NOAA/NWS' tropical cyclone breakpoints were udpated to include new coastal locations. A tropical cyclone breakpoint is defined as an agreed upon coastal location that can be chosen as one of two specific end points or designated places between which a tropical storm/hurricane watch/warning is in effect. The NWS designates the breakpoint locations along the U.S. East, Gulf, and California coasts, Puerto Rico, and Hawaii.
 
  3) New LayerInfo Web Service
     -> A LayerInfo web service was implemented to provide users access to additional useful layer (metadata-like) information not available through the use of nowCOAST map services, including legends, valid timestamps, icons, and layer descriptions. The web service was needed to address limitations of the GIS web mapping software used by nowCOAST, which makes it difficult and in some cases impossible to obtain additional information about each layer. You can learn more about the nowCOAST LayerInfo web service at:
http://nowcoast.noaa.gov/help/layerinfo.shtml?name=layerinfo
 




May 13, 2010
  1) "Geo-Referenced Links: Observations - In-Situ Stations - Meteorological & Oceanographic" map layers
     -> Added 15 new geo-referenced hyperlinks to AWOS meteorological/oceanographic observing stations and 3 new links to weather stations located on BP Oil Platforms in the Gulf of Mexico. Addition of these new stations was expedited to support the response to the Deepwater Horizon oil spill event.
 




April 19, 2010
  1) "Geo-Referenced Links: Surface Forecasts - Surface Weather" map layer
     -> Updated geo-referenced hyperlinks to Surface Weather Point Forecasts from the National Weather Service. This layer plots Weather Forecast Office (WFO) areas of responsibility for U.S. Territories, and allows users to obtain surface weather forecasts for any point on the map. The change was required due to scheduled modifications to WFO boundaries.
 
  2) "Geo-Referenced Links: Forecast Model Guidance - River" map layer
     -> Updated geo-referenced hyperlinks to Advanced Hydrologic Prediction System (AHPS) web pages operated by the National Weather Service due to a scheduled change in their web address.
 




April 15, 2010
  1) "Geo-Referenced Links: Observations - Remote Sensors - Wind Profilers" map layer
     -> Updated geo-referenced hyperlinks to Wind Profiler observation plots operated by the NOAA Profiler Network (NPN) and MADIS Cooperative Agency Profilers (CAP). Added links to several new wind profiler locations in U.S. and Japan and removed several non-working stations.
 
  2) "Geo-Referenced Links: Forecast Model Guidance - Oceanographic" map layer
     -> Updated geo-referenced hyperlinks to Extra Tropical Storm Surge (ETSS) web pages operated by the National Weather Service's Meteorological Development Laboratory (MDL) due to changes in the URL structure.
 




March 31, 2010

Enabled Web Map Service (WMS) access to nowCOAST map layers
     On March 31st, NOAA/National Ocean Service enabled OpenGIS Web Map Service (WMS) access to the map layers of NOAA's nowCOAST (http://nowcoast.noaa.gov), a GIS-based web mapping portal to surface observations and NOAA forecast products for U.S. coastal areas. A WMS is a standards-based web interface for requesting geo-registered map images for use by desktop, web, and handheld device clients (e.g. iPod). The nowCOAST WMS is part of a continuing effort to support NOAA's IT goals to "create composite geospatial data products that span NOAA Line and Program office missions" and "remove the physical barriers to geospatial data access with NOAA". WMS is a recommended web service of NOAA's Integrated Ocean Observing System (IOOS) Data Integration Framework.

     nowCOAST map layers are separated into six different Web Map Services, grouped by product or layer type. The six services are observations (obs), analyses, guidance, weather advisories, watches, warnings (wwa), forecasts, and geo-referenced hyperlinks (geolinks). The "obs" service contains near real-time observation layers (e.g. weather radar mosaic; GOES satellite cloud imagery; surface weather/ocean observations); the "analyses" service contains gridded weather and oceanographic analysis layers (e.g. global SST analysis; surface wind analyses); the "guidance" service provides nowcasts from oceanographic forecast modeling systems for estuaries and Great Lakes and coastal ocean operated by NOAA and U.S. Navy; the "wwa" service contains watches, warnings and advisory layers (e.g. tropical cyclone track & cone of uncertainty, short-duration storm-based warnings); The "forecasts" service includes gridded surface weather and marine forecast layers (e.g. National Digital Forecast Database's surface wind and significant wave forecasts); and the "geolinks" service contains nowCOAST's geo-referenced hyperlinks to web pages posting near-real-time observations and forecast product

These six services can be found at: http://nowcoast.noaa.gov/wms/com.esri.wms.Esrimap/name_of_service - where 'name_of_service' is one of the following: obs, analyses, guidance, wwa, forecasts or geolinks. For example, the WMS located at http://nowcoast.noaa.gov/wms/com.esri.wms.Esrimap/guidance contains forecast guidance from NOS and Navy oceanographic forecast modeling systems.

Detailed information on each service and how to utilize WMS effectively can be found at: http://nowcoast.noaa.gov/help/mapservices.shtml

To complement the WMS release, A LayerInfo web service was implemented to provide users access to additional useful layer (metadata-like) information not available through the use of nowCOAST map services, including legends, valid timestamps, icons, and layer descriptions. The web service was needed to address limitations of the GIS web mapping software used by nowCOAST, which makes it difficult and in some cases impossible to obtain additional information about each layer. You can learn more about the nowCOAST LayerInfo web service at:
http://nowcoast.noaa.gov/help/layerinfo.shtml?name=layerinfo

nowCOAST integrates near-real-time surface observational, satellite imagery, forecast, and warning products from NOS, NWS, NESDIS, and OAR and provides access to the information via its web-based map viewer and mapping services. nowCOAST was developed and is operated by NOS' Coast Survey Development Laboratory.
 




March 9, 2010
  1) "Geo-Referenced Links: Observations In-Situ Stations - Air Quality" map layer
     -> Updated geo-referenced hyperlinks to Air Quality observation web pages operated by U.S. EPA's AirNOW. Added over 50 additional hyperlinks to U.S. Cities displaying air quality observations, bringing the total number to over 315 cities.
 
  2) "Geo-Referenced Links: Surface Forecasts - Air Quality" map layer
     -> Updated geo-referenced hyperlinks to Air Quality forecast web pages operated by U.S. EPA's AirNOW. Added over 115 additional hyperlinks to U.S. Cities displaying air quality forecasts.
 
  3) "Geo-Referenced Links: Surface Forecasts - Terminal Aerodrome Forecast (TAF)" map layer
     -> Updated geo-referenced hyperlinks to Terminal Aerodrome Forecast web pages operated by NWS/AWC Aviation Digital Data Service.
     -> Added several new forecast sites around the globe, bringing the total number of hyperlinks to TAF locations on nowCOAST to over 1500.


The nowCOAST web-mapping portal, a product of NOAA's Coast Survey Development Lab, is monitored for reliability during normal business hours, Monday through Friday
