Spatially Explicit Criteria
We are trying to use the HRA model to look at cumulative impact of human activities on flatback turtle nesting grounds. We have a question regarding spatially explicit criteria.
We would like to consider spatial intensity of the stressors. We describe below two different examples:
- Infrastructure (stressor is “Habitat loss”). This is a polygon layer. Can we assign a rating to each infrastructure, i.e. each polygon, based on its area? So for instance a port with an area of 2km2 would have a rating of 3 and a small building of 10m2 would have a rating of 1. We would like then to input this polygon layer into the model. Can we directly copy this layer into the “Input \ Spatially-Explicit-Criteria \ Exposure” folder?
- Artificial lights: this is a raster layer showing the intensity of light in each 400mx400m cell.
(1) Can we directly input this raster layer into the model or does it need to be turned into a shapefile first? i.e. can we directly copy this layer into the “Input \ Spatially-Explicit-Criteria \ Exposure” folder?
(2) If it needs to be turned into a shapefile first, then we understand that the model will convert it back into a raster layer. How do we then make sure that the model retains the resolution, attribution and extent of the original raster layer?
Thank you in advance for your help
