acc_vec2fric: acc_vec2fric

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

Description

This function converts vector data into a raster layer containing travel speeds that can be used to create a friction map.

Usage

  acc_vec2fric(
  my_input,
  my_baselayer,
  my_speed = NULL,
  my_speedfield = NULL,
  my_datatype = "UInt16"
  )

Arguments

my_input	An input layer for the conversion. Should be of type SpatialPolygons(sp)
my_baselayer	A baselayer that defines resolution, extent and projection system of the friction map. Should be of class raster(raster). Most commonly a layer containing land-use values.
my_speed	Travel speed in km/h that applies to all polygons in this layer. If the travelspeed of polygons differs depending on a certain feature (e.g. paved/unpaved roads) use my_speedfield instead
my_speedfield	Column name of the input layer that contains travel speeds for the different polygons in km/h
my_datatype	GeoTiff datatype for temporary storage of data. Defaults to UInt16 storing integer values. For details see GDAL documentation.

Examples

  acc_vec2fric()
