Ecosys_risk.tiff gives wrong impression when habitat polygons border / HRA model
When I was looking at the output maps from my HRA model I noticed that cells that include the border between two habitats show a higher risk than they should when looking at the Ecosys_risk.tiff. I assume this happens because the cumulative risk is calculated for each cell per habitat and the ecosys_risk map is created by summing these rasters across habitats. In cells that have more than one habitat ideally you would want a weighted average according to the % cover of habitat in that cell or in a simplified version just cumulative risk divided by number of habitats. But since it sums these values I think this output gives the wrong impression when you have small habitats with lots of borders.
Since there are the maps of cumulative risk per habitat this problem is not that important for me but I am wondering if this also affects the html 'ecosystem-risk-plot'? In that case I might be better off by running the HRA model with a very small cell size to calculate this plot.
Hope you are able to help or confirm,
