I did not say you were challenging me. I'm talking about the final product being challenged by MegaMap Inc and osm being able to show where the data came from. osm if necessary could then obtain that data from me, the history of the origin of the data is in the database. >> No, if someone had better than consumer grade equipment >> then that should > > How do I take your word on that if you haven't proven yourself to be > honest in this matter and shown your working out?

I never said that users with better than consumer grade equipment should have an automatic right to this. There would of course have to be some sort of confirmation of capability by osm.

Hdop is not an indication of distance it is an indication of the confidence of the accuracy of the position and it is not readily translated to distance. So if you had an hdop of 8 then I would expect the position to be very inaccurate. -- Cheers Ross _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
