Hi,

I was wondering if it is possible to spatially sort (or even group) line data based on direction of flow?

I work for a waste water company and we are required to send out extracts of our GIS data (as a spreadsheet) to our contractors so they can clean the sewers.Currently the data is not sorted in any logical order,ideally it would be in an order they could actually follow when in the field and do continuous runs of cleaning when possible.The screenshot below is an example,with some suggested ordering for each section (though there would be multiple acceptable orders):

I don't know if it would be beneficial to group the data prior to trying to sort it?The order of the groups wouldn't matter too much,its just more to ensure the data always starts upstream in that group.

Any suggestions welcome.

Hello 亚搏国际在线官网community,
I have a dense hydrographic network on which I am performing topolical corrections.
What I wanna do is :
1.Extract start and end node of each line (Done using coordinate extractor + vertex creator)
2.Draw a circular buffer on each extracted node (Done using the bufferrer)
3.Keep only buffers which intersect with other lines (not done yet)
Is it possible to get some help doing this task ?
Thank you ver much.

Hi There,

I've got a question that seems to appear a fair bit within the forum but I have so far been unable to find a methodology that works for my case.

I'm attempting to identify water mains within a water distribution network that have accidentally been duplicated,incorrectly split and not removed,or more generally are errors that went unnoticed.What I think it boils down to is isolating where lines overlap exactly (Scenario B of attach image),where mains have been split and a segment wasn't retired/removed when (Scenario A),or where a segment was completely replaced the old segment wasn't removed or retired (Scenario C).*Orange segments below are the erroroneous segments I'm attempting to isolate.

From the forum posts I've read here there's a lot of talk of using the LineOnLineOverlayer which I have tried using.However,I'm don't want to report on valid intersects where mains are connected to each other.I've have some difficulty trying to weed these false positives out of my results.

I'm looking for some suggestions as to how I might be able to achieve this QA task.

Thanks,

Warren

I would like to write features into the versioned feature class which is participating in the geometric network.Unfortunately,if I good understand

https://knowledge.亚搏在线safe.com/articles/34856/working-with-esri-geometric-networks.html

this is not possible unless I drop geometric network and recreate it on the end of the process(of course this requires de-versioning of feature classes).

In my current project,de-versioning of feature classes and dropping of geometric network is not an option.This will require daily posting of all versions which is impossible in the current process 亚搏在线workflow.

Does somebody have an idea how I could implement solution in FME which would give me possibility to write records into a versioned FCL which belongs to geometrc network?At the moment I am thinking on implementing python caller which will perform this task...

Thanks in advance,

Dušan
