Tengo dos CSV conjuntos de datos: points CSV
y links CSV
.
He generado fácilmente los nodos en QGIS, pero no sé cómo hacer que las líneas entre los puntos.
Debe haber un tutorial o post anterior - por favor, ayudar, aquí están los detalles:
- punto de datos CSV de ejemplo, los diez primeros puntos

Las líneas necesidad de utilizar los nombres de nodo upstream_mh = manhole_no
y downstream_mh = manhole_no
