I have a raster image that has been reclassified into 15 equally incremented values/levels. This raster represents "sinkhole risk" in a certain county. So level 1 is the lowest risk region and level 15 is the highest risk region.
I also have the shapefile data for the actual sinkholes existing in that county.
My hope is to come up with some method of statistically analyzing the data by answering the following question:
"What percentage of the sinkholes are in the risk regions 1-3?" or
"What percentage of the sinkholes are in the risk regions 4-6?" etc...
Any suggestions on a tool to use or a general approach? I just need some guidance in the general right direction!
I posted a photo below for more clarity! The photo has been simplified into 3 values/levels, but my real map has 15 values.
I am using ArcMap 10.1.
