acc_ras2fric: acc_ras2fric

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

Description

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

Usage

  acc_ras2fric(
  my_input,
  my_baselayer,
  resampling_method="max",
  my_reclass_inputvalues = NULL,
  my_reclass_outputvalues = NULL,
  my_datatype = "UInt16"
  )

Arguments

my_input	An input layer for the conversion. Should be of type raster(raster)
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. Can be the same layer as the input layer
resampling_method	Defines the method used to resample the raster values into lower resolutions. Defaults to maximum. Other options contain ("near"|"bilinear"|"cubic"|"cubicspline"|"lanczos"|"average"|"mode"|"max"|"min"|"med"|"q1"|"q3", see GDAL documentation for more information.
my_reclass_inputvalues	A vector with all unique values from the input raster that should be reclassified into travel speeds
my_reclass_outputvalues	A vector with all travelspeeds for reclassification. Should be of the same length and in the corresponding order to reclassify values in my_reclass_inputvalues
my_datatype	GeoTiff datatype for temporary storage of data. Defaults to UInt16 storing integer values. For details see GDAL documentation.
