Closed Loop Roads - Removing Duplicate Points Causes Errors

[AssetChris]

Hi,

I use LRS frequently and it does a better job than many proprietary asset management software packages.

At City of Mandurah we have four roads that are closed loops, i.e. the start and end are exactly the same point locations. This causes one of the points to be removed, which then generates the 'Not enough points' error. Could you consider making LRS keep duplicate points? I can send examples in Shapefile if required.

Thanks,

You are building LRS from loop line + 2 milestone points which have exactly the same coordinates?

It seems difficult. It is already complicated enough to guess direction from milestones which may have wrong values and order.

Say that we allow to have multiple milestones with different measures (km/miles) at the same offset along the line (which could be useful also for discontinuous measures after road straightening). Then it would be necessary to test all combinations switching the order of measures on duplicate milestones, to find the best order.

The line would have to be really closed loop and direction guess treated in a special way not just switching the duplicate milestones measures but also trying to shift start/end in milestones circle, because we had no line ends. Plus some additional work to rebuild the polyline to respect measure start/end.

Well, probably feasible but recently I have absolutely no time nor eagerness to do that as a voluntary work. If you are interested in a long term and you can sponsor the work, send me an email.
