I'm aiming to do a similarity analysis between a raster layer and a vector layer.
The raster layer is a 5-class ice map and the vector layer (points) contains ice jam events data. The goal here is to determine if there is a trend/pattern in the surroundings of the ice jam events that can be seen on the ice map.
I've created buffer layers around the ice jam events (50m, 100m, 500m) and I'd like to have statistics on how much of each class of the raster underneath is present within the buffer. Ex: 42% class-1, 22% class-2, 8% class-3 and so on.
I'm hoping to use QGIS/Grass GIS tools to solve this.
I'm fairly new to the software.
