I have points that I have created from vector lines. To be more specific these points are end and start points of vector lines. But what I want to do now is identify which points connect to each other without manually doing this. Is this possible?
How to identify points that fall on the the same line:
- Add a unique ID to the line layer. Use the Field Calculator to add a new numerical field, with the expression
- Do a spatial join between the point layer and the line layer. Now all the points that fall on line share an attribute.
- Use the shared attribute to identify which points are connected by lines. Eg, you could apply a categorized style using this field.
