I am producing a state wide natural disaster risk map and would like some advice on how and if it may be possible to use the produced map to redraw administrative boundaries.
The Risk map will be a raster reclassified to values 1-100 representing the risk score calculated from several different layers. What I would then like to do is use this to create a certain number, say 12, administrative areas specifically designed to be made up of areas of similar sizes, with similar (or at least as similar as possible) attributes. Specifically think a bushfire/wildfire risk map being used to create total fire ban zones.
I imagine there is the potential to do this by converting the raster to polygons for each value and aggregating or dissolving with distance and value range inputs, but perhaps someone can point me in the right direction of a more efficient approach.
