[OSM-talk] segments as polylines & errors.

[Hamish]

Hi,

I have just posted the segments -> polyline GRASS vector map and
instructions on how to do statistical analysis and threshold display/
extraction by length, etc., for GRASS GIS 6.1-cvs (grass.ibiblio.org)
at:
  http://hamish.bowman.googlepages.com/gpsdrivefiles

In addition the GRASS "v.clean error=new_map" command can be used to
pull out duplicate lines, broken lines, etc. The v.digit module or QGIS
vector digitizer can be used to quickly highlight and fix problems.

I hope it is of use to you,


Hamish

ps - these errors/modifications along the way,

"ways" -> "routes". "way" is too close to "waypoints"

{classes,highway}:
 k="highway" -> k="class" (didn't check for double use)

oneway: true->yes,  no->""
