Measures the distance of each cell to the nearest MPA edge and to all MPA cells
Source:R/get_mpa_distances.R
get_distance_to_mpas.RdMeasures the distance of each cell to the nearest MPA edge and to all MPA cells
Arguments
- mpa_locations
a dataframe with at least column coordinate columns x,y,and mpa (TRUE or FALSE)
- resolution
the resolution of the simulation system. Can supply a vector
c(x,y)to denote an X by Y system, or one number to denote an X by X system- patch_area
the area of each patch
Value
a dataframe with two columns added.
distance_to_mpa_edge measures the distance from each patch to the nearest MPA edge in units of sqrt(patch_area), with negative values indicating areas inside an MPA
total_mpa_distance measure to total distance to all MPA cells from each patch, in units of sqrt(patch_area)
