humanfootprint_indicator {mapme.biodiversity} | R Documentation |
Calculate human footprint statistics
Description
Human footprint data measures the pressure imposed on the natural environment by different dimensions of human actions. The theoretical maximum value, representing the highest level of human pressure, is 50. This routine allows to extract zonal statistics of the human footprint data.
Usage
calc_humanfootprint(engine = "extract", stats = "mean")
Arguments
engine |
The preferred processing functions from either one of "zonal", "extract" or "exactextract" as character. |
stats |
Function to be applied to compute statistics for polygons either one or multiple inputs as character. Supported statistics are: "mean", "median", "sd", "min", "max", "sum" "var". |

Value
A function that returns an indicator tibble the humanfootprint
as variable and the associated value (unitless) per year.
