Unexpected results #16

Open anna-lojacomo opened 2 years ago

anna-lojacomo commented 2 years ago

Hi, this function is exactly what I am looking for, but for some reason it is giving me strange results.

I would expect KP values to increase away from the start point of my line: first_point Instead these are the KP: KP ...and these DOL values: DOL they don't seem related to line distance, or at least I can't see how.

I tried dissolving the line, changing from British National Grid projection to UTM, using points snapped to the line, looking at the interactive and point options, but all of them give the same results.

Any ideas?

Hi, I solved the problem finally by converting from a MultiLineString to a LineString!

Hi Anna,

Thanks for reporting this, I'm going to reopen the issue as a reminder - for the next version it will check if it's a multiLineString and warn the user.

Sounds good, merry christmas :)

Hello, I've tested several MultiLineStrings and a MultiLineStringZ and got correct results. If you have the files still on hand after 3 months, you are welcome to send them to me so I could check this.

Hi,

I've attached the dataset I had used. I checked again and I seem to still get strange results with it, not too sure how to explain it.

Let me know if there is any other information from me that would help you!

Cheers, Anna

It seems that the files haven't come through. Could you upload them when answering in Github, perhaps? Thanks!
