Extract distances and surface areas from a spatial objectSource:
This function returns a matrix of distances between locations (in kilometer) along with a vector surface areas of the locations (in square kilometer).
a spatial object that can be handled by the
name or number of the column to use as rownames and colnames for the output distance matrix (optional, NULL by default). A vector with length equal to the number of locations can also be used.
a boolean indicating if a progress bar should be displayed.
A list composed of two elements. The first element is a squared matrix representing the great-circle distance (in kilometer) between locations. The second element is a vector containing the surface area of each location (in square kilometer).
geometry must be projected in a valid coordinate reference
system. It will be reprojected in degrees longitude/latitude to compute the
great-circle distances between centroids' locations with an internal function
and to compute the surface area with the function st_area from
the sf package.
The outputs are based on the locations contained in
sorted in the same order. An optional
id can also be provided to be used as
names for the outputs.
