Or just set your own starting point? (some landmark, like a canon http://www.twickenham-museum.org.uk/detail.asp?ContentID=276) It will be good to have the building outlines all very well mapped and relative position to each other but it will not be perfect because: - relative to the rest of OSM will be in metres accuracy because the other items are positioned in metres accuracy. - doesn't everything(trig points, land, space, etc.) move millimetres each year?

What is it derived from? - The Total Station is being borrowed without the condition that any data collected belongs to the owner (e.g. if you were collecting it on time you should be working). - The trig points or based station? These are publicly viewable landmarks and if you weren't allowed to use them they would be locked up or guarded. -- Gregory [email protected] http://www.livingwithdragons.com
