I'm using QGIS 2/12.3
I have a point layer with modelled data on a 1km grid, each point has a value (0-5, modelling temperatures) and lies at the centre point of a 1km grid square.
I also have a polygon layer which is of 1km squares.
I need to assign the points values to the corresponding polygons.
If I use intersect, the output layer is points, not polygons.
(I need to do this so I can intersect the km squares with another layer to find the average value for each polygon).
I realise one way might be to add a new column to the attribute table and paste data across - but I need some guidance.
