These maps of natural capital are derived from predictive modelling. Data from sample locations is extrapolated up to an England level using statistical modelling. With predictive maps of natural capital, it is important to consider the scale at which the information is presented. There are inherent trade-offs when using fine or coarse scale spatial resolutions. The choice of spatial scale in model predictions can influence:
- The accuracy of prediction
- The uncertainty of the prediction
We investigated both of these issues in detail to decide an appropriate spatial scale to use. Based on the results of this investigation, it was decided that, 1km resolution was the most appropriate scale for this project.
