I have a polygon shapefile of many lakes, I also have a point shapefile of locations on those lakes where fish were caught.
The point shapefile contains the attributes: Fisherman_iD, Fish_Caught, Lat, Long.
The polygon shapefile contains the attributes Lake_name, Points_per_polygon(PNTCNT)
Each point obviously has differing entries under the fish_caught field.
What I want to get is the average fish caught per lake (polygon).
So I need to have a total number of fish caught, per individual polygon, and then I can divide that by the PNTCNT file I create using the Points in a Polygon tool.
Ideas? I am relatively new to QGIS.
