Hi,
I have been looking at the OS openmap local vector dataset. I noticed that the coordinates in there are centimetre level accuracy. I am speculating how the OS made this dataset a "nominal viewing scale" of 1:10000. Scales are somewhat irrelevant to vector data. Have they degraded the geometry points by thinning or averaging, or is the data still at survey level accuracy? I have some old (paid for) OS master map data. It would be interesting to compare the polygons in there with the the openmap local ones. But before I search my loft for the disc, has anyone already done this?
Roger
