I am in the process of changing an existing website over to Xoops, and was wondering the best way\module to display Members details by region.

The existing sitehttp://www.samb.co.uk/localbaker.htm uses a Map ( which I will use in Xoops) that points to the members in that area. What module can display members details by region (category) – Not all members have website details, so address details and possible company summary would be good – Members DO NOT need to amend their own details, I am happy to do this for them

Any suggestions would be greatly appreciated.

You could try XDirectory? I haven't used it, but it could be what you're looking for.
