[OSM-talk] Converting Polish/.MP to OSM?

Hi,
I have finally gotten around to uploading some of the Calgary Trails Project data... under the username 'catmp'. I made a slight mod the converter to remove attribution/RoadID on nodes within a way as this was making/will make cleaning up of traces difficult.

I think there is a bug with the POLYGON stuff. Look in the Calgary area (BOW RIVER polygons), they are mostly right but 'jump' to nodes not in the original polygon. So it looks like something is up with the 'previously used' node stuff.

For example (frigged the name to make it findable in output)
---
[POLYGON]
Type=0x48
Label=BLOW RIVER
Data0=(50.93128,-113.99972),(50.93116,-113.99959),(50.93172,-113.99959),(50.93214,-113.99998),(50.93279,-114.00093),(50.93288,-114.00122),(50.93270,-114.00196),(50.93262,-114.00212),(50.93253,-114.00199),(50.93227,-114.00067),(50.93163,-113.99990),(50.93150,-113.99993)

I am not 100% convinced of the tags, apparently the route up Turtle
Mountain is 'bicycle=yes'... this is definately NOT the case!!!! Don't
know whether this is source data problem, or with the parsing of the
garmin attributes.

(these are revertable/removable quite easily as there are isolated on their own)

Way too late to do much more on this tonight (errr.. this morning). Cheers,
Simon.
