I have this project wherein I should be able to display the route from one child node towards a parent node in QGIS. Attached is a simple photo to demonstrate my question:
The specifications are as follows:
The path from a child to a parent is always unique (for example: route from child 1 to parent node = Line 1B -> Line BA -> Line AP)
The nodes and the lines are separate shapefiles
So here's my question:
a. Can this be done by a query statement without having to rely to a plugin?
b. If this is not possible, what plugin should I use?
