R Documentation

Make a buffer width scenario.

Description

This function assists with preparing heat source land cover data input to evaluate different buffer width scenarios.

Usage

lcdata_buffer(
  node_id = NA_real_,
  stream_id = NA_character_,
  aspect,
  skygap,
  vegwd_L,
  vegwd_R,
  lccode_L,
  lccode_R,
  lccode_noveg,
  lccode_stream,
  trans_dir = c(45, 90, 135, 180, 225, 270, 315, 360),
  transsample_count,
  transsample_distance
)

Arguments

`node_id`	Unique heat source node ID. Optional. Default is NA.
`stream_id`	Unique stream identifier. Optional. Default is NA.
`aspect`	The stream aspect in degrees. Can be a vector.
`skygap`	The distance (meters) between the left and right bank vegetation buffers where there is open sky. This distance is about the same as the active channel width. Can take a vector of values as input.
`vegwd_L`	The width of the vegetation buffer on the left bank (meters) looking downstream. Can take a vector of values as input.
`vegwd_R`	The width of the vegetation buffer on the right bank (meters) looking downstream. Can take a vector of values as input.
`lccode_L`	The numeric land cover code to use for samples that fall inside the vegetated buffer on the left bank. Do not use zero.
`lccode_R`	The numeric land cover code to use for samples that fall inside the vegetated buffer on the right bank. Do not use zero.
`lccode_noveg`	The numeric land cover code to use for samples that fall outside the vegetated buffer. Do not use zero.
`lccode_stream`	The numeric land cover code to use for samples that fall on the stream. Do not use zero.
`trans_dir`	A vector of integer values corresponding to the specific azimuth directions of the sample transects. Default is Heat Source 9 directions = c(45, 90, 135, 180, 225, 270, 315, 360)
`transsample_count`	Number of samples per transect. The number does not include the sample at the stream node.
`transsample_distance`	The distance between transect samples (meters).

Details

The arguments aspect, skygap, vegwd_L, and vegwd_R can take a vector of multiple values. When this is the case all combinations of the supplied vectors are used to map the land cover codes. The returned data frame will have a row for each unique combination.
