acc_euclid: acc_euclid

In mapme-initiative/mapme.accessibility: Creation of Accessibility Maps in R

Description

This is a wrapper function to use rgrass7 to calculate an euclidean distance map with the r.grow.distance function.

Usage

  acc_euclid(
  my_sources_raster,
  grassbin,
  my_metric = "euclidean"
  )

Arguments

my_sources_raster	This should be a layer containing the sources. Should be of type raster(raster). Can be created using the acc_vec2fric function on a vector layer
my_metric	Distance metric to be used. Defaults to "euclidean". Can be also squared|maximum|manhattan|geodesic. For details see https://grass.osgeo.org/grass72/manuals/r.grow.distance.html
grassbin	Define here the path to the grass binaries. An easy way to find the binaries is to use the "findGRASS" function from the the package "link2GI". Consider installing it if you do not know the GRASS location and are unable to find it manually.
