I have data from Geonames.org on the location of population centres, provided in the format of
Center Name, Latitude and Longitude.
Only one latitude and longitude point is provided for each population centre.
I would like to create a layer that turns these points into a shapefile of catchment areas around each Population centre, similar to State or Local Government Area set of boundaries.
This could be done e.g. by drawing a boundary between two points at the midpoint between those points.
Is there a way in QGIS to generate these shapefiles automatically?
