The Jeppesen 10-9E Low Visibility taxi chart flow pattern does not concur with BWI Ground Control taxi charts. We contacted Ground Control before push and asked if we could expect Runway 10 instead of Runway 15R due to the flow pattern shown on 10-9E SMGCS Low Visibility chart. Taxiing to Runway 15R was against the directional flow pattern shown on Taxiway F. We explained our concern to the Ground Controller. This was not an option because their charts did not show Runway 10 for departure during low visibility operation from our position at the new Midfield Cargo Complex. Our charts show taxi available to Runway 10. We discussed this to our Dispatcher; Duty pilot and Ops. We requested a 'follow me' service provided by the airport to guide us safely though the low visibility to Runway 15R. [I suggest] a revision to BWI Ground control SMGCS (Surface Movement Guidance and Control System) Low Visibility taxi charts for departures to Runway 10 from Midfield Cargo Complex as shown on Jeppesen Low Visibility SMGCS chart 10-9E; [and also] change taxi flow direction for operation from Midfield Cargo to Runway 15R.
During pre-departure briefing; we noticed that SMGCS (Surface Movement Guidance and Control System) Low Visibility taxi chart for Runway 10 and Runway 15R; from our current position; we could only use Runway 10 for departure. I contacted BWI Ground to request Runway 10 for departure. BWI Ground responded that due to low visibility procedures in effect; Runway 10 was in use for arrivals and Runway 15R for departure and our taxi route would be [Taxiways] G; F; P to Runway 15R. I explained to him that according to the SMGCS chart we would be taxiing against flow on Taxiway F and we could taxi to Runway 10. Ground responded that he did not have charts for a low visibility taxi to Runway 10. We contacted Dispatch; Duty Pilot and Ops. We requested a 'follow me' to guide us to Runway 15R on the expected route and departed.[I recommend] BWI Ground update their SMGCS charts and establish a low visibility taxi route to go from Midfield Cargo to Runway 15R.
