Simplification for multiple tracks

[lsf]

I do a lot of network analysis.  Over time, the networks end up having a lot of data points because the network merging algorithm tries to maintain all of the useful information.  I am aware of the track simplification capability, but it only works on a single track.  Many of my networks have more than 20 tracks within the network (some have a lot more).   It is a bit tedious to do this for each track individually.

Could you add the capability to apply the simplification to all active tracks?  This would allow me to simplify the whole network (or multiple networks) at one shot.

There is probably some complexity under this request.  Some tracks are traversed very frequently, so there are lots of points and a big simplification opportunity.  Other tracks may have been traversed only once or twice, so the number of points is sparse by comparison.  I would ideally like to have TopoFusion recognize the situations and apply more simplification where the data reduction is the greatest without introducing significant loss of accuracy.  So if I specify a number of points or a percentage reduction (another request), TopoFusion determines how to best meet this goal.

Yep, there definitely needs to be a multi-track simplify tool of some kind.

One thought would be to be able to set a "points per mile" guideline.  That way longer tracks can use more points than shorter ones.

It should / will be included as a part of the network algorithm in the future.  The current method ends up with too many points as you've indicated.

I think a simplify dialog that works on all tracks within a file would be useful for other stuff, too.

Thanks.

Just to tie them together, that's effectively a seconding of a suggestion here
