Narrative:
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.
