I have 32k of <br>polygons representing every lot in the city of Montreal in 1903. I also <br>have the 1901 census returns coded by household (95k of them) to those <br>lots. Is there a simple way to have Qgis place points within each lot <br>polygon for the corresponding households?<br>Thanks in advance.<br>Robert<br><br>-- <br>Robert C.H.
