NOAA/NOS nowCOAST Status Message

8:00 AM EDT Friday March 17, 2017

Subject: Updated: Modification of NOAA's nowCOAST map

services to provide maps of NOAA/NESDIS Global Mosaic

of Geostationary Satellite Imagery and mosaic of

shortwave infrared imagery from NOAA GOES EAST and

          WEST effective April 4, 2017

Updated to change effective date to on or about April 4, 2017, and

removeMeteosat-7 from list of weather satellites whose imagery is

used in the generation of GMGSI

Users of the existing map service should update their

applications to use the new URL after the new service becomes

available. The specific changes users need to make depend on the

type of protocol or endpoints used.

Effective Tuesday, April 4, 2017, NOAA's nowCOAST (trademarked)

(https://nowcoast.noaa.gov <https://nowcoast.noaa.gov/>) will provide 
users with access to

NOAA/NESDIS's Global Mosaic of Geostationary Satellite Imagery

(GMGSI) and GOES shortwave infrared imagery via nowCOAST's time-

enabled web mapping services. The new imagery will be available

onnowCOAST's map services via two protocols: GeoServices

Representational State Transfer (REST) map services and Open

Geospatial Consortium (OGC) compliant Web Map Services (WMS).

To properly reflect the addition of GMGSI to nowCOAST, the name

of the nowCOAST map service will change from

sat_meteo_imagery_goes_time to sat_meteo_imagery_time. Users of

the existing map service should update their applications to use

the new URL after April 4. The specific changes users need to

make depend on the type of protocol or endpoints used.

Users of REST Map Service Endpoints:

The existing REST Map Service endpoint at the following URL:

https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/sat_meteo_imagery_goes_time/MapServer

After April 4, 2017, the link will be replaced with:

https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/sat_meteo_imagery_time/MapServer

An HTTP redirect will be implemented to reduce the immediate

impact of the changes to certain users of REST map service

endpoints; however, the change is expected to break client

applications that do not support HTTP redirect usage. All users

are encouraged to switch to the new map service endpoint as soon

as possible following implementation. Users will be able to

continue using their existing layer identifiers to access the

GOES visible, water vapor, and longwave infrared imagery, but

will need to make further modifications to their applications if

they wish to display the new GOES shortwave infrared or GMGSI

imagery layers.

Users of WMS Endpoints:

The existing WMS endpoint at the following URL:

https://nowcoast.noaa.gov/arcgis/services/nowcoast/sat_meteo_imagery_goes_time/MapServer/WMSServer

will be replaced, after April 4, with:

https://nowcoast.noaa.gov/arcgis/services/nowcoast/sat_meteo_imagery_time/MapServer/WMSServer

This change will cause disruption of service to any client

applications still connecting to the discontinued WMS endpoint

after implementation. Users of WMS endpoints will need to update

their applications according to the updated capabilities

Extensible Markup Language (XML) file obtained via a

GetCapabilities request to continue displaying GOES imagery or

to add the new imagery if desired.

Additional information for users of WMS and REST map service

endpoint will be found at

https://nowcoast.noaa.gov/help/#!section=wms-layer-ids 
<https://nowcoast.noaa.gov/help/#%21section=wms-layer-ids>

and

https://nowcoast.noaa.gov/help/#!section=rest-layers-ids 
<https://nowcoast.noaa.gov/help/#%21section=rest-layers-ids>

respectively.

The above nowCOAST URLs will not contain information about the

new imagery until the new version is implemented.

Detailed Information about the new nowCOAST map service will befound at

https://nowcoast.noaa.gov/arcgis/rest/services/nowcoast/sat_meteo_imagery_time/MapServer

This URL will not be accessible until the new version isimplemented.

The GMGSI includes visible, shortwave infrared, and longwave

infrared imagery. The addition of the GMGSI will provide, for

the first time on nowCOAST, weather satellite coverage for U.S.

territories west of Hawaii. In addition, a mosaic of shortwave

infrared imagery from GOES WEST and EAST will also now be

available.  The shortwave infrared imagery provides additional

cloud information as well as fog detection at night.  The GMGSI

has a spatial resolution of 8 km and is composed of imagery from

U.S. GOES, Meteosat-10, and Himawari-8 weather

satellites.   GMGSI will be updated approximately every 3 hours

in the nowCOAST map service and the mosaic of GOES West and East

shortwave infrared imagery will be updated every 30 minutes to

ensure the latest imagery are available to users as soon as it

becomes available from NESDIS.  Additional information about the

NESDIS GMGSI can be found athttp://www.ospo.noaa.gov/Products/imagery/

nowCOAST provides coastal intelligence on present and future

environmental conditions for coastal and maritime users by

integrating data and information from across NOAA and other

federal and state agencies. nowCOAST was developed by

NOAA/National Ocean Service’s Coast Survey Development

Laboratory, and is hosted on NOAA’s Integrated Dissemination

Program (IDP) infrastructure where it is monitored 24 x 7 by

NWS/NCEP Central Operations.
