I've designed a google doc spreadsheet that allows players to quickly and easily compile an easy-to-read reference map. These maps do not hold any information that isn't already available to anyone who scrolls the map themselves. But, when coordinating with other players, can save hours of time.
With spider's go ahead, anyone willing to start plotting their map, get in touch with me. I'll host the spreadsheet, and implement conditions that will auto color code your map, based on the player you list in a hex.
