Thanks for all the comments, I can fully appretiate not altering the global database to achieve workarounds. I am finding it good practice to work on my own OSM files now to test faults with routing in my area, this change was loaded to global but I'll refrain from that in future.

I know one day some clever fella will figure it out or maybe I'll get some time to have a look.

Are you sure you hadn't been drinking Chris ;-)

Thanks for the hints. I've been keeping an eye on the GPS sat fix and it generally has 7 or 8 sats and reports an accuracy of 5m which I'm pretty pleased with. I guess I basically need to collect repetitive data and make sure it fits in with other land marks. It seams to be mainly the smaller residential roads which are out. The main roads are accurate to my track logs so I wonder if the residential roads might have been done from knowing the area rather than GPS surveying.....

You're not alone ;-) I've been really getting interested in the power grid off the south east of England. I live in tunbridge wells and so far found that one source is 132Kv from dungeness nuclear powerstation near lydd. You know I started doing my mapping in Google Maps but it's so slow and now I've found OSM I'm going to update it all in here. I really want to know if TW has a redundant system and infact how the english power companies manage the grid.

I guess this internet's so big that no one has a unique special interest ;-)

Interesting stuff about the cowboys. I've seen similar documentaries and those guys have a cool job!!!
