FOLLOWING LOW MINIMUM ARR TO RWY 16R AT SEA; FLT CREW OF B737-300 DISCOVER LOW VISIBILITY HOLDING POINTS ON ARPT SURFACE DO NOT MATCH THOSE ON COMMERCIAL SMGCS LOW VISIBILITY TAXI PAGES.

Narrative

WE PERFORMED AN HGS CAT IIIA APCH TO RWY 16R AT SEA. TWR DIRECTED US TO TURN OFF ON TXWY N; WHICH WE DID. AFTER CLRING RWY 16L; WE TURNED L TO PROCEED TO THE GATE (RVR WAS 700-800 FT) ONTO TXWY B. WELL; THE FIRST PINK SPOT WE CAME TO WAS SPOT 11 WHICH IMMEDIATELY BLEW MY MIND BECAUSE THAT WAS SUPPOSED TO BE ON TXWY B WELL S OF A TERMINAL. THANKFULLY; I COULD BARELY MAKE OUT ANOTHER CARRIER JET AT THE GATE; WHICH I KNEW WAS IN THE X CONCOURSE AND WE SAFELY NAVED OUR WAY TO OUR GATE. THE PROB IS THAT THE SMGCS COMMERCIAL CHART DATED FEB/FRI/04 (ALTHOUGH CURRENT) DOES NOT MATCH THE ACTUAL ARPT MARKINGS. I ASKED THE GND CTLR ON THE TAXI OUT ABOUT THAT AND HE SAID THE MARKINGS ON THE ARPT HAD BEEN CHANGED; BUT THE 10-9A DID NOT CURRENTLY REFLECT IT. MAYBE AN ASAP ALERT; DISPATCH NOTE/REMARK FOR INBOUNDS/OUTBOUNDS TO SEA WOULD BE IN ORDER UNTIL THE CHART MAKERS CATCH UP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RESPONSIBLE AGENCIES ARE NOW AWARE OF THE PROB. TEMPORARY LOW VISIBILITY TAXI PROCS ARE IN EFFECT FOR SEA UNTIL THE MARKINGS AND CHARTS ARE MADE COMPATIBLE.
