My first query on here. I'm using QGIS.
I've created a gridded map by counting points in each grid:
This was generated by counting the number of observation points per grid(polygon).
The attribute table in the observation (polygon) layer looks like this:
But I now wish to create a similar gridded map, but instead of just counting the number of points within each grid, I wish to count the contribution of each author_id within each grid and add a column which shows the highest contributor within each grid.
Is this doable?
