I use QGIS 2.18.16.
I import 1.000.000 data points, from a text document, as a CSV layer. Then I add a raster of 5 by 5m over those points.
Project, layer and raster are put in the same CRS (Belgian Lambert 72) After that I count points in polygon.
This works fine.
How do I count point in polygon for up to 5 million data points or more? When I import more then 1 million I can't count points in polygon no more.
