THE DISCONTINUATION IS ONLY FOR THE LEGACY REDBOOK GRAPHIC
FORMAT. PRODUCTS WILL REMAIN AVAILABLE IN THE FOLLOWING FORMATS:
(1) STATIC GRAPHICS INTERCHANGE FORMAT (GIF) IMAGES
(2) SHAPEFILE FORMAT
(3) KML FORMAT
(4) GRIDDED FORMAT [(I.E. NATIONAL DIGITAL FORECAST DATABASE
(NDFD)]
REMOVING THE LEGACY REDBOOK GRAPHICS SUPPORTS NWS'S NEED TO MAKE
FORECAST PRODUCTION AND DISSEMINATION MORE EFFICIENT. NCEP HAS
RECEIVED FEEDBACK AT CONFERENCES AND THROUGH OTHER STAKEHOLDER
INTERACTIONS INDICATING THAT THE LEGACY REDBOOK GRAPHIC FORMAT
FOR THESE PRODUCTS IS RARELY USED. THE MAJORITY OF USERS PREFER
OTHER AVAILABLE FORMATS, SUCH AS THE STATIC GRAPHICS INTERCHANGE
FORMAT (GIF) IMAGES AND GIS SHAPEFILE FORMAT, AND ARE ACCESSIBLE
VIA THE WEB.
EXAMPLES AND ACCESS TO THESE PROPOSED REMAINING FORMATS ARE
AVAILABLE AT:
