NOAA nowCOAST Status Message
9:00 AM EDT Thu May 4, 2017

Effective as of late yesterday, May 3, 2017 NOAA's nowCOAST (
https://nowcoast.noaa.gov) provides 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 is available on nowCOAST'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 has changed from

sat_meteo_imagery_goes_time to sat_meteo_imagery_time. Users of

the existing map service need to update their applications to use

the new URL. The specific changes users need to

make depend on the type of protocol or endpoints used.

Users of REST Map Service Endpoints please use the following:



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 please use the following:



This change will cause disruption of service to any client

applications still connecting to the discontinued WMS endpoint. Users of
WMS endpoints 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





Detailed Information about the new nowCOAST map service can be

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 at


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.
