How to Cut Lines at Points? Need Tips for Automating with Python

GIS_Rookie

Hi everyone,

I’m working on a project using LiDAR data to scan lines, and I’ve run into a challenge I hope someone here can help with.

Long story short: the line wires were not connected, so I extended the parallel lines by 5m and generated points where the extended lines intersect. However, I’m now stuck trying to figure out how to cut the lines at these intersection points and remove the small, useless segments that were created by the extension.

Here’s an example image of the situation:

 

Does anyone have ideas or tips for automating this process using Python? Any help or pointers would be greatly appreciated! 

P.s. I don’t have the license to use the Split Line At Point tool.

 

Thanks in advance!

Best regards,

What you should be able to do is use the Split Line at Point tool. Select your line layer and the point layer that you created where the lines intersect. This will split the lines at each point. Then, you can just do a select by attribute based on the length column and delete any lines 5m or less (this is assuming that you don't have any legitimate lines that are 5m or less that you need to keep).
