| Dec 18, 2015 at 15:37 | comment | added | traggatmot | Hmm, when I do this using the Zonal Statistics tool, it creates a new raster, and doesn't append the maximum (or average, but I'm looking for a maximum values) to the vector layer layer's attribute table. I have had to use the Zonal Statistics as Table tool and then perform a spatial join between the resulting table and the original vector layer. | |

The raster covers every single zone feature and I also selected ignore null values while running the tool. | |

The principle involved is that when you're analyzing raster data, using raster procedures (which of course requires raster software like SA) tends to be far more efficient (in its use of your time, the computer's time, and the computer's RAM) than converting rasters to vector format and using vector procedures. | |
